• How do you measure a window for replacement

    Having decided to replace the old windows with plastic, you need to calculate the estimate. The price of the new window depends on many factors: fittings, profile thickness, and some chambers, but one of the primary price formers will be the size. In addition, you will need to measure the parameters of the opening on your own without the manufacturer’s help. As a rule, the panel construction windows are not remarkably different, but in brick buildings, the difference may be a few centimeters. So how to measure a window without resorting to the help of specialists?

    What you need to know about window openings

    As mentioned above, window openings do not have the exact standard dimensions. For example, panel houses have approximately identical dimensions because they are made in the same shape, and the difference is insignificant. However, in a brick house, especially an older construction, the difference is substantial and can be from a few to tens of millimeters.

    The second nuance is that during the shrinkage of the house, the window openings can distort and have differences in some respects.

    In private homes, the dimensions do not have a single standard; the more important is the material of the walls and shrinkage, with subsequent deformation of the window openings. In such cases, you must make measurements for a plastic window and reconcile everything repeatedly.

    There is also a concept of a window with and without a quarter in window terminology. This part of the window opening is called a ledge in the wall from the outside (street) side, designed to fix the window from the living room. A quarter can be as large as 30 millimeters. In private construction, such an element is ignored, but it is present in the construction of apartment buildings built before the middle of the last century. So, how do you measure windows for replacement with plastic?

    How to measure a window with a quarter

    Suppose the window opening has a ledge in the quarter. In that case, the window system installation will be carried out from inside the room, so it is necessary to measure the opening with specifics. In the presence of such a ledge, measure the window width by the outer (street) slope, adding 40-60 mm to the figure. After that, it is worth measuring the inside width. The future window should not exceed the dimensions of the internal index.

    The window height is the figure from the bottom slope, minus 10-20 millimeters on the gap, up to the top adding at the same time 30 mm to fix the window in a quarter.

    Ideally, the following parameters should be observed when installing window systems in an opening with a quarter:

    1. Install under the bottom of the frame drainage gap from the edge of the quarter is a maximum of 20 millimeters.
    2. The frame goes behind the side ledges for 20-30 mm.
    3. Behind the top shelf, the window comes in 20 mm.
    4. The entire window system does not touch the walls of the opening, with a mounting gap.

    When these parameters are met, the plastic window should fit securely in the opening and be locked.

    How to measure a window without a quarter

    Independently measuring the window without a quarter in the opening is quite simple. First, the width of the future frame should match the space, minus tolerance for the installation gap. Next, the window’s height is calculated from the bottom slope to the top, removing the hole for mounting and allowing window sill installation.

    To calculate the sill parameters do the following calculations:

    1. Width – the wall thickness on the inside plus the sill overhang.
    2. Length – tolerance of 80 mm on both sides is added to the width of the opening.

    When replacing the exterior sills and window sills inside, it is worth bearing in mind that the thickness of the new window system is less than that of the old wooden windows.

    Correctly measuring the window is quite a sensitive procedure and is worth checking. After all, if the manufactured system will be a little less, you can still fix it, but if the parameters are significant, such a window will not fit in the opening. Therefore, the best way to measure the window to install the plastic window is to call an experienced estimator from the manufacturer, the price of the issue is not so high, and a professional will do their job quickly and efficiently.

    Proper measurement of the plastic windows plays an essential role in construction operations.

    PVC windows have replaced the old wooden frames almost everywhere. The cost of metal-plastic construction is justified by its manufacturability and performance characteristics, and for the installation, they often ask for an inflated price. The main thing in this case – is the correct measurement; the rest of the work can be done without special skills and knowledge.

    Measuring window openings

    With “quarters”

    Openings with “quarters” are distinguished by the presence of protrusions inward from the outside. Their size is 50 mm in panel houses and 65 mm in brick ones. These elements do not allow the window to fall out into the street and close the gaps from the ingress of moisture and wind.

    Measurement should start from the outside. Open the sashes and use construction tape to measure the distance between the edges of the quarters. It is advisable to take three measurements:

    • In the middle of the opening,
    • from below,
    • from above.

    From the values obtained, choose the smallest and add 20 – 30 mm to it (30 – 50 for a brick house).

    Measuring the window opening for PVC windows with “quarters.”

    The entire width of the space will be larger, but that is the effect we were seeking. We must leave a gap under the technological joint, which will be filled with polyurethane foam in the installation process. So, we found out how to correctly measure the window’s width.

    For height, you must know the distance from the edge of the upper quarter to the bottom of the window opening. The technological joint will be about 1.5 – 2.5 cm so that the window will be raised on this value, and the “quarter” will perform its function.

    But if you wish to install a window sill and a sill, you will need a particular stand profile, and in this case, you will have to reduce the window’s height by 30-50 mm.

    How to measure? In the diagram on the right, the value D reduced by the height of the support profile (30-50 mm) will give us the window size.

    Window opening without “quarters.”

    Windows without “quarters” are even easier to measure. It would help if you chose such sizes that there must be 1.5-3 cm assembly gaps on all perimeter sides.

    If you intend to install a window sill and the sill, you need to reduce the width to 30 – 50 mm, depending on the model and company manufacturer.

    We were opening for a window without sills and trim.

    Keep in mind that measurements should be taken between the walls. If they are covered with plaster, soffits, and other finishing materials, they should be removed or find a way to measure the thickness of the finish.

    In simple terms, regardless of the design of the window openings, you should pick up such metal-plastic windows, which will have a gap between their ends and the walls of 1.5 – 3 mm. This distance will be needed to fill the installation foam after preliminary fixation with anchor plates.

    Here you can see how to measure the insulating glass unit, considering the foam’s gaps.

    Before you measure the plastic windows yourself, you should think: if you doubt your abilities, it may be better to entrust this procedure to professionals.

    1. First, they are guaranteed to do everything right.
    2. Secondly, in case of failure, the company that did the installation will be responsible.

    Changing windows for plastic – how to make a correct measurement of the opening

    You need to calculate the estimate after deciding to replace the old windows with plastic ones. The price of the new window depends on many factors: the fittings, the thickness of the profile, and the number of chambers, but one of the leading price formers will be the size. In addition, you will need to measure the parameters of the opening on your own without the manufacturer’s help. As a rule, the panel construction windows are not remarkably different, but in brick buildings, the difference may be a few centimeters. So how to measure a window without resorting to the help of specialists?

    What you need to know about window openings

    As mentioned above, window openings do not have the exact standard dimensions. For example, panel houses have approximately the precise measurements because they are made in a uniform shape, and the difference is insignificant. However, in a brick house, especially older constructions, the difference is significant and can be from a few to tens of millimeters.

    The second nuance is that during the shrinkage of the house, the window openings may warp and have differences in some respects.

    In private homes, the dimensions do not have a single standard; the more important is the material of the walls and shrinkage, with subsequent deformation of the window openings. In such cases, you must make measurements for a plastic window and reconcile everything repeatedly.

    There is also a concept of a window with and without a quarter in window terminology. This part of the window opening is called a ledge in the wall from the outside (street) side, designed to fix the window from the living room. A quarter can be as large as 30 millimeters. In private construction, such an element is ignored, but it is present in the construction of apartment buildings built before the middle of the last century. So, how do you measure windows for replacement with plastic?

    How to measure a window with a quarter

    If the window opening has a ledge in the quarter, then the window system installation will be carried out from inside the room, so it is necessary to measure the door with the specifics. In the presence of such a ledge, measure the window width by the outer (street) slope, adding 40-60 mm to the figure. After that, it is worth measuring the inside width. The future window should not exceed the dimensions of the internal index.

    The window height is the figure from the bottom slope, minus 10-20 millimeters on the gap, up to the top adding at the same time 30 mm to fix the window in a quarter.

    Ideally, the following parameters should be observed when installing window systems in an opening with a quarter:

    1. Install under the bottom of the frame drainage gap from the edge of the quarter is a maximum of 20 millimeters.
    2. The frame goes behind the side ledges for 20-30 mm.
    3. Behind the top shelf, the window comes in 20 mm.
    4. The entire window system does not touch the walls of the opening, with a mounting gap.

    How to measure a window for replacement

    Before taking the size of the window, it is necessary to know the peculiarities of its opening and configuration. It is recommended to approach the measurements carefully since in panel houses, the dimensions of window structures are about the same, and brick buildings – may differ by a few centimeters. We suggest you use this instruction if you want to install metal-plastic windows yourself. You also need to know how to measure a PVC window to determine approximately how much the windows will cost.

    Rules for measuring windows

    You should measure your home window from the street to the living room. Both measurements are required to determine the depth of the window opening. But, first, it is necessary to know that the window should be no smaller than its outer part. And how much more extensive? This is what we should calculate.

    Remember that the opening can be skewed, especially in panel houses, so you need to increase the size of the structure by the size of the skew. After you determine the window’s dimensions, you should compare them to the internal measurements of the opening. This will allow you to find mechanical errors in your calculations earlier and then estimate what plaster should apply to the interior soffits.

    Before you measure the size of the window, take care to have the following tools at hand and prepare: a device for measuring, pliers, a chisel in blunted form (15-20 mm), a building level, a hammer of small size, a pencil, a ruler, a rubber band, a paper to record the result. It is convenient to measure with a tape measure or a telescopic ruler. The accuracy of measurement should be 10 millimeters.

    Measurement of windows in a dwelling house with a quarter

    Window openings in houses with a quarter should go outside the top and side soffits by 20-30 millimeters. If you decide to get serious about measuring your window, you should keep this in mind. The window width should be calculated on the outside soffits, and it is to her added 40-60 millimeters for a window on both sides in a quarter or slightly less if the wall is crooked.

    After measuring the width between the exterior soffits, the result should be checked that it was not more than the distance between the points where the inner soffits adjoin the frame. The width of the window frame must not be greater than the width of the frame on the inside.

    If the window width is more significant during the inspection, you should contact a professional measurer. The window’s height is the distance from the base of the opening to the top slope minus 10-20 millimeters, which falls on the gap for the assembly foam, and 20-30 millimeters, which is needed for entry into the upper quarter of the design.

    If you are planning to use a false profile when installing the windows, which is a must when equipping the sill and the sill, then you should reduce the window’s height by another 30 millimeters (the size of the false profile). So now you know how to correctly measure a plastic window in a building with a quarter!

    To verify your work, check the following dimensions: The height of the window frame without the undercut profile must not exceed the distance from the window sill to the upper window sill from the inside. Likewise, the size of the window with a sill profile must not exceed the length between the lower edge of the sill and the upper internal soffit.

    Measuring a window opening in a residential home without a quarter

    Take the height and width of the window before measuring the plastic window. When calculating the width, measure at the top and bottom of the space, and take the smallest value in subsequent calculations. The width of the opening should be subtracted by 20-40 millimeters (gaps for foam on both sides); we will consider the width of the plastic window.

    The height is measured from the right and left side openings. From the more petite figure, subtract 20-40 millimeters (gaps for the foam) and 30 millimeters (height standoff profile). This will be the height of the window.

    Measuring the window width

    To get the window size, you will need to add 3 to 5 cm to the outside lining width (a little less if you have a curved wall). To measure the window accurately, you need to know a few details:

    • the window should be the same or slightly wider at the point where the frame touches the linings;
    • the design should be smaller than the inside opening of the window.

    To avoid making mistakes when measuring windows in non-standard openings, it is necessary to contact a specialist. A professional window measurer can locate the cause of the discrepancy on the spot.

    Measuring the window height

    When measuring the window height, it is recommended to subtract 2 centimeters from the distance from the base of the window opening to the upper exterior soffit. This is the required distance at the top of the door for the installation foam.

    The scheme of measuring the window height is simple enough and understandable to every builder. To design went into the upper quarter, add 1.5-2.5 centimeters to this size. When installing a sill window, use a standing profile, and from the resulting size, subtract 3 centimeters.

    Tips for window design

    The actual window design is determined by the color and configuration of the existing window. The products should, if possible, be the same on the facade of the building. When designing the design, you need to consider some practical recommendations and technological constraints:

    The sash dimensions specified in the window system catalog should not be larger than the maximum:

    • due to the limited possibilities of the perimeter hardware, the width of the tilt-and-turn sash must not be less than 400 millimeters;
    • the diameter of the end of the semi-circular arch must reach 520 millimeters;
    • Dimensions of openings may differ due to the floor arrangement and other factors, so the measurement is made during the construction and reconstruction of the building, and all dimensions are consistent with the project.

    Thus, you have learned how to correctly measure windows in residential buildings with a quarter and without a quarter. There is a methodology for making calculations on the height and the width. Prepare all the necessary tools for the work in advance so you do not interrupt the process! This way, you can determine the cost of future metal and plastic construction.

    How to measure a window opening for plastic windows

    Given the popularity of plastic window constructions nowadays, the question often arises: how to measure them correctly? It would seem that there is nothing more accessible, but the rules of their measurement are not so simple. Observing these requirements allows the owner of the house or office to save money and time. Furthermore, there is an opportunity to immediately install those windows that fit perfectly to the size of the window openings.

    Measuring window openings: general rules of work with their own hands

    It is no secret that all construction and repair work is subject to general mathematical rules. This statement fully applies to such an essential matter as measuring window openings for plastic windows. Existing measurement rules allow you to quickly and easily install exactly those plastic windows that are ideal for a particular room. So, what are they:

    • The prospective estimator should have an analytical mind, good spatial thinking, and personal experience in installing windows;
    • Measurements should be made both inside and outside. The inside of a plastic window is always more extensive than the outside;
    • Before you begin to measure, it is necessary to finish all preparatory work (laying bricks, removing old plaster, etc.);
    • In many houses (especially panel houses), there is a skew of the window opening. To avoid the appearance of gaps, it is necessary to keep the minimum standards of the plastic window leaf: the size of the inside of the window is 30-40 mm wider and 15-20 mm higher than the outside;
    • Before you begin installing the window, compare its size with the calculations made at the initial stage. There may be a mechanical error that will nullify all the work done in the previous steps.

    These rules are mandatory for any craftsman to measure and install windows and insulate glass in apartments, offices, and private homes.

    How to measure a window “with a quarter”

    Marking of measurement parameters

    Window opening “with a quarter” is challenging to call symmetrical. If you use the structural features of the building, in which there is a presence of “1/4”, misalignment is not only possible but also mandatory. So what is a 1/4 window opening? So: a “with 1/4” window opening is an opening in which you can observe a protrusion along the outer window perimeter of the leaf by 1/4 part of the length of the brick from the overall level of the window opening. Specialists consider the calculations of the window opening for a plastic window “with 1/4” the most time-consuming and require special attention. Such measurements are defined by their own rules, the observance of which is obligatory for any master.

    How to measure frames for plastic windows

    • the structure is behind the side quarter of not less than 20-40 mm;
    • Behind the structure windows’ upper wall are at a distance that should not be less than 15-20 mm.

    Width

    This data is easy enough to calculate: the width of the existing window aperture between its jambs on the outside + 40-60 mm to complete the frame’s necessary winding beyond the window’s boundaries. The amount received must not exceed the width of the opening, which has a plastic window on its inside linings.

    The use of a base profile

    Using a base profile to mount a plastic window will make the task easier.

    Suppose you will use a modern base profile to install plastic windows. In that case, you must be sure to observe the following requirements: window height = distance from the base of the opening for a plastic window to its upper slope – 10-20 mm (the lower gap, which is needed for successful installation) – 30 mm (required to install the base profile) + 20 mm (the distance at which the frame must go behind the upper quarter).

    How to measure “without a quarter” openings

    Measurement of windows “without 1/4” is also subject to its rules.

    Auxiliary values

    The width of the window sill depends directly on the width of the window opening. An essential condition is the window sill should never completely overlap the radiators used to heat the room. The sill length depends on the width of the street side of the opening, to which you must add 60-80 mm. The width of the sill is the distance from the edge of the sill to the window frame. It is possible when the sill protrudes about 30-50 mm from the outer edge of the house wall. Window sill length is the total length of window aperture + 100-110 mm on each side.

    Width

    It is necessary to take the width of the window opening and subtract from it 20-40 mm (the distance needed to create a mounting gap). If the wall has a high curvature, the installer must take an indent of 40 mm.

    Height

    The height of the window frame is one of the essential values without which it is impossible to measure. To determine the height of the plastic window frame, it is worth doing the following: from the height of the window opening, subtract the size of the support profile – usually 30 mm – and subtract the size of the upper installation clearance (15-20 mm). This difference will be the required height of the plastic window frame.

    How to measure a window yourself

    Do you know what a quarter is? What is a reverse? Or a straight opening? If you have no idea what it is, don’t even try to measure it yourself. With the apparent similarity of urban development, measuring windows can be radically different in two seemingly identical houses. Therefore, there can not be explicit instruction.

    Meter, as a rule, is a former installer who knows this or that type of building, but even experienced professionals with 5-7 years of experience make mistakes. And even they are sometimes forced to measure the slopes or remove a part of them. And the tool he has is not only a tape measure but also a hammer and chisel, and sometimes a crowbar. So, first of all, determine the type of your opening.

    1. This is a unique structure of a concrete or brick wall. In this case, the size of the window on the street side is less than the size of the opening from the room, by 5-25 cm. Approximately 80% of the development of the city of Moscow has this size. Most of the traditional panel houses have a quarter, and in brick houses, it is almost always present.

    Reverse quarter. Happens rarely, mainly in the end parts of buildings. In this case, the outside size is larger than the inside. So here, to measure the structure should be especially careful.

    Straight opening – the size of the window from the outside is the same as from the inside. Mostly, this is a private development.

    Combinations

    You know, openings with a quarter on the sides, but not at the top and bottom. And then there’s the reverse situation, upstairs and downstairs there is, but left and right there isn’t. The top may be plain, the bottom the opposite, and vice versa. All of these indicators form many combinations.

    If you think an apartment has a one-quarter window, then the others are the same, you are deeply mistaken, and they can be different. And then there is a specific type of house, where they were inserted in the production of a concrete slab, and the slope was poured with a concrete-based mixture there as well. So it appears to be a square opening when you look at it visually.

    But when you dismantle it, those slopes collapse, and the opening gets bigger. And there are not a few houses like this. Based on years of experience, it’s a real art to identify and account for all of this. For example, in wooden structures, everything is usually boarded up so that you can’t see anything. A true professional will remove anything that obstructs inspection.

    Therefore:

    Before you measure, heed the advice: without an extreme need, do not order plastic structures measured by you personally. There is a high probability that the facilities will be smaller than required, and then there will not be enough light in your room. And even worse, if it is larger, you will have to remodel the window or enlarge the opening, which is very problematic.

    If you want to know the approximate size, just measure the length and width of your window with a tape measure from the room side. To calculate over the phone is enough; the error will be no more than a thousand rubles and can even be in your favor.

    If you need to measure yourself.

    Therefore, we will tell you how to measure windows with quarter and straight walls. We will leave the reverse and other cases to the experts.

    I measured with a quarter.

    The size from the street side is smaller than the size of the room. To measure the window width, measure the outside distance from one side jamb to the other, holding the end of the tape as close to the frame as possible. Add 3 to 6 centimeters to this dimension. For example, if the width is 140 cm, the measurement should be 146 cm.

    To protect yourself from mistakes as much as possible, measure the width from the side of the room. It should be at least 5 cm more than the window, less than 151 cm. If the distance is less, for example, 148 cm, reduce it to 143 cm. This is 100% for panel houses; the quarter can be plastered in brick houses. The plasterer will be removed, so do not add less than 6 cm in brick.

    If the inner distance turns out to be much larger than the product, for example, 160 cm or even more, do not be tempted to make the structures larger. Although, in this case, the plastic frame will be entirely behind the quarter, and there will be only glass on the street, this threatens freezing due to incorrect measurement.

    To measure the height, also take the length of the outer opening, from the sill to the upper exterior slope; usually, this is the height of the product. To her, nothing is added, as under the window is a set profile, a height of 3 cm, to which the window sill is attached. That is, if the size – is 150 cm, the product will be 150 cm plus the support profile, in total – 153 cm. Also, check yourself by measuring the height of the room. It should not be less than 5 cm or more than 150cm, which is not less than 155 cm.

    Measuring a straight opening

    Flat straight walls are often found in private wooden and brick houses. Therefore, measuring the width and subtracting 4-6 cm is necessary. For example, if the width is 150 cm, the construction is 144-145 cm.

    Size in height – minus 8-10 cm; that is, if the value of 150 cm, the window’s height is 142 cm. Then, another 3 cm stand profile is a total value – of 145 cm.

    If you measure in an old house, clean the surfaces, and remove the trim, you should see a natural look without details. If the building is wooden, it’s not so bad; when you install it, you can expand it, for example, with an ax (and it happens).

    And one more thing – if possible, call a measurer, or remove the old product before measuring, do not risk expensive products, plastic construction – not a cheap pleasure.

    How to measure a window

    Everyone facing the installation of plastic windows for the first time asks, “where should I start? For the first installation of windows was successful and you will get a good result, you need to read the materials on our website, which contain all the necessary information on installing plastic windows.

    The first and most important job is entrusted to the fitter. Quite often, the customer is completely unaware of the walls of his house and what is inside them. In this regard, simply calling with a description of your window to order the necessary window will not be enough.

    To inform the customer about the parameters of the window opening, of course, can, but to establish the full extent of the upcoming work can only a professional with a decent experience in this area of service. A good specialist must have analytical skills, be knowledgeable about future window construction, and have personal experience installing windows.

    Basic rules of measurement

    Measurements for the future plastic window should be carried out from inside the opening (indoors) and outside (outdoors). The parameters of these measurements are vital to determine how deep the quarter has an existing window opening. After all, many factors affect the final size of the window.

    One factor to consider when measuring may be a skew in the existing opening; if present, the window size should be increased by the amount of the skew. To avoid gaps between the window and the edge of the space, the size of the PVC window must be 3-4 cm and 1.5-2 cm higher than the outside width and height, respectively.

    This can be achieved by increasing the window structure’s overall size or enlarging the window. In the second case, you will use additional profiles snapped on the box. After determining the parameters of the future window, they must be compared with the reference (internal) parameters of the window opening.

    In making such a comparison, any errors that may have been made in previous calculations may be detected, an assessment made of how thick a layer of plaster will be applied to the internal soffits to compare the window edges, and whether the soffits will need to be torn down when installing the window construction. The amount of such extra work should be kept to a minimum.

    Performing the measurement requires:

    1. Proper measurement of the parameters of the opening.
    2. Accurate calculation of the dimensions of structures (overall and internal) will be made.
    3. We are considering the dimensions of the window sill, mosquito nets, and sills.
    4. Coordination with the customer of the following:
    5. what kind of window coverings there will be;
    6. choice of style and configuration of the window;
    7. color solution for seals, sash, and hardware;
    8. choosing the type of insulating glass unit;
    9. to determine the number, type, color, and design of roller shutters and mosquito nets;
    10. I am choosing the material, color, and dimensions for the sills, window sill, and window blind.
    11. The unification of the overall dimensions of future constructions.
    12. Diligent sheet design containing data about the measurement and recommendations for the installation process.

    How to measure a window yourself

    The most convenient for measuring the opening is a tape measure equipped with a digital display or telescopic ruler, and you can also use a standard tape measure for 5 meters with 18 mm tape. The opening may or may not have quarters (a ¼ brick protrusion on the outside of the wall to the inside of the space). Spaces with quarters most often you can meet in city houses, openings without quarters – in suburban cottages.

    The opening height is measured twice on the left and right sides, while the width is calculated once at the bottom. If in doubt about the location of the elements of the opening contour relative to the horizontal and vertical, it is necessary to use a level to determine the deviation and correct all calculations.

    The size of the structure in the opening without quarters will be 2-4 centimeters more minor than the corresponding dimensions of the door. In addition, the vertical size must be reduced by the thickness of the window sill, which will be installed under the window frame in the future.

    Calculation of the parameters of the opening with quarters and the parameters of the future window construction is a more complicated process, especially when measuring the beginning of old windows and doors.

    First, it is necessary to determine the thickness and height of the window sills and take measurements of the height and width between the outer quarters and the inner soffits at the wall near the window. The future window’s width should, on average, exceed the width between the extreme quarters by 6 centimeters (3-9 cm).

    If there is a difference between the sizes of more than 6 cm, it is advisable to apply wooden (rough) or PVC extensions. As for the height of the future window, it should be 3-6 centimeters more than the distance between the outer quarters vertically. The frame overlap into the bottom quarter shall not exceed 2 cm.

    In the upper quarter, the frame can go as far as the size of the mosquito net allows. If there is no vertical quarter or upper quarter, the penetration into the vertical quarter will be 1.5 + 4.5 centimeters, and into the lower quarter 2 centimeters. 1 + 2 centimeters from the wall is left for the insulation.

    If you want to measure a window with a balcony door, you must measure the parameters of the door and window and the overall parameters of the door with the window. For example, to calculate the door’s width, consider the door’s bottom. The bottom end of the door frame and the stone base must have a 1.5 +2 cm gap between them for insulation.

    The height of the arched type structures is measured every 10-15 centimeters across the width of one half.

    If in doubt about the method of closing the window structure (for example, in the case of a tight fit of the upper rung to the reinforced concrete waler), you can use a hammer and blunt chisel to remove the casing and beat off a small piece of material from the wall. So you can avoid errors in the size of the future window.

    All these measurements are not difficult to perform as a professional, so we recommend you call for FREE measuring and order installation of plastic window designs on our site.

    Tips regarding window design

    Sash sizes must comply with the standards specified in the catalog of window systems and not exceed the maximum possible. The tilt-and-turn sash should be no less than 40 cm in width. The glass size accessible for washing from one side should not be more than 0.55 m, and the size of glass accessible from both sides is not more than 1.00 m. Semi-circular PVC-arch can be at least 52 cm in width (bending diameter).

    During the design of partitions for offices and glazing of the loggia, should not forget that the movement of structural elements through any doors in the apartment should pass without problems.

    When measuring during the construction or reconstruction of a structure, the weight and dimensions must be coordinated with the project. Windows for a new house or cottage should be selected, considering the style in which the building is built.

    How to measure a window correctly.

    To measure the window correctly, it is necessary to consider that the size depends on the window’s features. For example, panel houses have standard doors, but in brick houses, openings may differ by a few centimeters or even be non-standard (arbitrary). Therefore, in the case of houses made of brick, measuring the windows should be especially careful.

    Measure the window yourself, without resorting to the services of a measuring man from the firm to install windows. Knowing the size of the wooden window will be easier to calculate the approximate cost of the finished product. Of course, it is easier to take window measures if the house is newly built and the window apertures are empty, but with the old windows, it will be a little more complicated but also doable.

    Remove the size of the windows in a wooden house (new)

    In a wooden place, there are no quarters (ledges on three sides of the opening, to which the window). So you can choose where to install a wooden window on the wall. Most often, it is installed flush with the exterior wall. Since this option will be easier to do exterior decoration windows, i.e., do not need the outer lining – you can do only the casing.

    Let’s proceed directly to taking the measurements. To begin with, we measure the window opening along its width. To do this, measure the door from the top and bottom. If the dimensions are not identical, we will take the smaller one and subtract 50 mm from it (the installation joint under the foam is 25 mm on each side). The width of the window is known, then measure the height. Again, take the same size, take the more minor and subtract from it 50 mm.

    Here there is one nuance – the presence and thickness of window sills. Standard milling made under the window sill in the bottom bar is 30 mm. It is normal if the window sill is the same thickness or slightly less. If the window sill turns out to be thicker, the difference between the thickness of the sill board and the milling should be subtracted from the window’s height.

    If a wooden house has a rugged frame, the opening for the window is measured inside the frame. Then, the width of the outer casing is determined by considering the roughcast box. The standard size of the box is – 5 cm.

    To calculate the width of the architrave added to the wall and the box at 2 cm (on both sides, we get 4 cm), we shall add 5 cm (chest) plus 25 mm (joint under the foam). We obtain the result – the trim width must be 11.5 cm.

    How to measure a window in a panel house (residential)

    The panel house has old windows, which complicates the measuring a little. Dismantling the old windows is impossible because it can take months to make new wooden ones. Panel houses have window openings with a quarter – a ledge on three sides (two on the sides and one on top).

    We need to determine the width of the window opening from the outside (from one quarter to the other). To do this, measure the distance between the quarters through the open window (be very careful!). Then we measure the opening inside the room, from one slope to the other.

    From the inner opening, we subtract the outer; as a result, we get the depth of the quarters. Let’s take, for example, the width of the outside of 1380 mm, and the inside of 1500 mm. The resulting difference of 120 mm divide by two, and we get a result of 60 mm – the width of the quarter. So now you can measure the width of the window.

    Adding to the outside dimension on each side of 30 mm – 1380 + 30 + 30 = 1440 mm, this is the width of the window. The window’s height is measured this way: the lower part should be at the level of the outer sill, and in the upper quarter is added 30 mm. For example, the height from the top quarter to the sill is 1400 mm, then adding 30 mm to the window’s height is 1430 mm. As a result, the window size to order is 1440 x 1430 mm.

    How to remove the size of the window in a brick house

    In brick houses, or as they are called “Stalinist,” the quarters can be quite deep – up to 10 cm. Modern windows cannot be driven into quarters more than 3 cm; otherwise, the window frame will be hidden, and the exterior walls will come right up against the glass. The thickness of the window frame and sashes (in the closed position) is 110 mm.

    Now you can measure the window, but remember that there can be many nuances in this case as each window is individual. So it is better to contact a company to install the windows; only then can you be sure everything is done correctly.

    How to measure the opening for a plastic window with his hands

    Measuring a plastic window directly depends on the size of the door you will make in your home. If the size of your entry is non-standard, and you are worried that you will not be able to insert the window into it properly, do not despair. Nowadays, plastic windows are made to any individual size and shape.

    But if you already have windows from another material that you want to replace with plastic, measuring the opening with your own hands, then this article is for you. First, we will tell you how to make the correct measurement of gaps for plastic windows in doors that have a “quarter” (a quarter is a ledge on the outer sides of the window in half a brick, to which the window frame is attached), in width:

    Since the window itself goes over the quarter by 1.5-2.5 cm from the side, you need to add 3-5 cm to the inside size of the window – this will be the correct size of the window you will buy.

    Explaining the above: the actual size of the window will be slightly wider than the one you measure inside (touching the inner side linings). This is because the window’s width will be less than the width of the opening with a window sill.

    Now measure the window height:

    • If measured from the outside, 2 cm is subtracted from the height between the outer upper slope and the base of the opening for the installation foam.
    • Then add 1.5-2.5 cm to this size so the window can enter the upper quarter.
    • If you have a window with a sill and a sill, then subtract 3 cm from the resulting size because we need to know precisely the size of the window.

    If you use a base profile, the height and width of the window will be less by 3-8 cm, which will go to the installation foam. However, sometimes it happens that the quarter is more than 5 cm. In this case, an additional profile is used to not leave much room for the installation foam.

    If your opening does not have a quarter, then the correct measurement of the plastic window will be as follows:

    1. Subtract 3-8 cm from the width of the opening.
    2. Subtract 5-6 cm from the height of the opening, 3 cm of which will go to the base profile and the rest of the mounting foam.

    Measuring the window opening in sections

    In conclusion, we draw your attention to the fact that the walls often have curvatures that must be considered. On this basis, the windows should be measured on minor sides (the expansion of the wall can always be covered with foam). If you are not planning to install plastic windows yourself, we recommend inviting a specialist to measure the windows accurately.

    Window Measurement

    To measure the opening for the installation of the window should be treated very responsibly. After all, a wrong measurement can lead to the fact that it will have to do additional costly work or remake the plastic window. Therefore, most companies producing windows do not recommend size alone.

    They are not responsible for the correspondence of the size of the manufactured window to the window opening if the measurement is made by the customer and not a specialist from the company.

    But sometimes, it is necessary to measure the window opening by yourself. In this case, it is essential to follow the guide to measure the windows exactly correctly.

    There are two types of window openings:

    • with a quarter
    • no quarter.

    A quarter is a ledge on the sides and top of the window opening that prevents the window from falling out and protects against the penetration of precipitation and wind inside the room. The width of a quarter in a panel house is 50 mm; in a brick house – 65 mm, or ¼ of a brick.

    Measuring a plastic window

    Measuring a window takes place in 4 steps:

    1. calculating the size of the window opening
    2. sill measurement
    3. window sill measurement

    Measurement of the window opening begins with the street side, then moves to the inside. To do this, open the window and measure the width of the space between the quarters at the top and bottom. These data may be different. To the smallest of the obtained results, add 3-5 cm if the house is paneled and 4-6 cm for a building made of brick. This value will be the width of the window.

    To this value must be added 2-3 cm to overlap the quarter and subtract 2 cm for the thickness of the mounting foam. Finally, you will use a trim profile if the window has a sill and a sill. In this case, the value of the height of the window is reduced by another 3 cm. If the measurement is done correctly, the size will be almost equal to the distance from the end of the upper quarter to the upper edge of the sill.

    If the window opening is not quartered, subtract 3-8 cm for the installation clearance when calculating the window width. The height is calculated by subtracting 5-6 cm from the opening size, of which 3 cm is for the support profile.

    The length and width of the drip molding are calculated as follows: 5 cm is added to the distance between the left and right quarters. This is the length of the drip molding. To calculate its width, add 2 cm to the distance from the end of the quarters to the window.

    The window sill is measured from the room side. It should be taken into account that the new plastic window is only 5-6 cm thick, while the previous windows are more expansive. Therefore, to calculate the sill width, subtract 5-6 cm from the distance from the old window’s outer sash to the sill’s edge.

    The sill length is the distance from the edge to the edge of the window opening. The width and height of the sill are measured along the inside of the window opening. All values must be written down in millimeters.

    If you are building a wooden log house, do not forget to consider that the log house will “sit” for at least two years. If the windows will be installed as soon as the log house is assembled, when calculating the height of the window from the size of the opening, subtract 10-15% for shrinkage and another 5-6 cm for installation. The width of the window is measured as described above.

    If you do not consider the settlement of the log house, the lowered upper rings of the log house may break the window. Therefore, experts recommend installing windows in the log house only after shrinkage. The method of installing windows in the log house is different from the usual since there should not be a rigid fixing to the logs to avoid breaking the window or “hanging” the upper wings.

    Used casing, which is attached to the bar and inserted into the vertical groove cut into the ends of the logs of the window opening. In this case, the wreaths can move down on the bar without breaking the window and not hanging.

    If possible, it is worth entrusting the measurement of windows to an employee who will produce and install windows. In this case, you can be sure of the correctness of the size. In addition, the company will be responsible for the manufacturing and installation of windows. If the measurement is made independently, then you will be accountable.

    How to measure the opening for a plastic window?

    Measure the window opening for a plastic window is an obligatory and essential activity because the accuracy of these measurements determines the window’s correct installation and successful operation. Moreover, you should understand that even in the typical apartment building is necessary to measure the opening for a plastic window because they may be different, and there may be openings of irregular shape or with an uneven thickness of the walls.

    It would help if you entrusted the measurement of the window opening to a specialist who will competently make the measurement, taking into consideration all the peculiarities and imperfections of your window opening and allowing avoiding troubles with the plastic window in the future.

    Consequences of incorrect measurement

    It is imperative that the measurement of the window opening was performed with accuracy to the millimeter. If the measure was wrong and the window is smaller than the required size, the gap will have to be sealed with foam or build up the window jambs. This process will require additional materials and time.

    After some time (perhaps a few years or months), such a window begins to warp, and cracks and gaps appear. Moreover, the window starts to let in cold air and freeze in the wintertime. With high humidity, you can not avoid constant condensation on the window and mold formation. Also, the window loses its aesthetic appearance.

    Before starting the work, those who still dared to measure the window opening must determine precisely what materials will be used for the interior and exterior decoration of the walls and the window soffits. But, first, consider the general rules for measuring window openings of all types.

    When measuring the window opening, it is essential to understand that the window frame must not rest against the doorway. The gap between the frame and the space is called a mounting gap and is designed to allow for natural structure expansion. According to the standards, such a gap should be from 2 to 5 cm. Therefore, measuring the window opening inside and outside the room is essential.

    To determine the window’s width, you must measure the window opening at the top edge, bottom, and middle, and then select the smallest value.

    To determine the height, measure the opening in three places (right, middle, left) and from the smallest value, calculate the window size. Now consider in more detail, depending on the type of window opening.

    Measuring the window opening without a “quarter.”

    To determine the width of the frame of the future window, from the width of the window opening (the smallest value of the three measured), subtract the size of the necessary installation clearance of 20-40 mm, depending on the curvature of the wall. For example, if you see that the vertical parts of the opening have a significant drop, it is better to take 40 mm.

    The height of the window frame is defined as the difference between the height of the window opening (the smaller of the three vertical measurements) and the size of the installation clearance in the upper part (15-20 mm), and the size of the support profile (30 mm).

    It is also necessary to calculate the size of the window sill and sill. If you have an old window sill, simply measure it with a tape measure. If the window sill is not installed, you need to add 50-100 mm to the width of the window opening to determine the length. The sill width depends on the depth of the window opening.

    Measuring the window aperture with a “quarter.”

    Window openings with a quarter, i.e., a projection on the outer perimeter of the window by a quarter of brick, are more challenging to measure. Quarters in most cases are not symmetrical; there may be misalignments. When measuring a window with a quarter, it is essential to know a few basic rules:

    The window frame should go behind the side quarter on 20-40 mm and for the upper wall – 15-20 mm. This is because the base profile must be 10-20 mm higher than the bottom wall, and it is necessary to attach the sill correctly. The width of the window frame is defined as the width of the window opening between the outside lining and 40-60 mm for the frame factory for the quarters.

    It must be ensured that the width received does not exceed the width of the opening on the inner soffits and does not exceed the distance between the points of adjacency of the inner soffits and the frame.

    Suppose a support profile is to be used to install the window. In that case, the height of the window is determined as follows: the value from the base of the opening to the total rebate minus 10-20 mm (for installation clearance from below), minus 30 mm for the support profile, and 20 mm for the approach of the frame beyond the upper quarter.

    The window’s height must not exceed the value from the bottom of the sill to the top of the inner sill. The window sill and sill dimensions are determined similarly to those for window openings without quarters.
