Measuring windows is anything but a straightforward process. Even the smallest mismeasurement can lead to significant problems and wasted money.
This article will give you a guide on how to measure a window for replacement. So, check through it to make sure you have everything you need, then follow the instructions to get the right sizes for your future installation. By the end, you should also know who to call to take those measurements and put perfect windows in place.
Tools Needed for Window Measurement
While a tape measure might be an obvious tool, it is the best option for getting exact measurements without using electronic devices. Note that you should record such distances in millimeters for precision. Inches or even centimeters may not be accurate enough and can cause gaps to appear around the window.
Make sure you also have a notepad and pencil or pen to write down the sizes you measure, as well as a level to ensure you measure a flat and even plane. If you can source one, get a straight edge, or if not, a ruler should suffice. This will help you check how straight the windows are.
Depending on the specific location, you may need a ladder or step stool. Avoid climbing on the building itself, and make sure to always follow safety guidelines when using such a ladder.
How to Measure a Window for Replacement
You need to make sure that the width and height measurements are consistent. If there is a variance in any of these, even after double-checking, use the smallest distance. You can secure and fill in any extra space later, ensuring the frame does not let in drafts.
How to Accurately Measure Window Width
Start at either top corner of the window and measure to the other top corner. Then, do the same at the bottom of the window, followed by a third measurement of the middle of the two. Determine the middle point of the window using a tape measure, then mark it with a pencil for reference moving forward.
Perform the check again to ensure the accuracy of your measurements. Do not move on until you are confident of each. You can then compare all three distances to check for consistency.
If you find any variance, you can perform the check a final time to be sure. As mentioned above, though, use the smallest measurement.
How to Accurately Measure Window Height
When you want to measure window length, also known as height, perform the same steps as with its width. Only this time, instead of tracking the top, middle, and bottom, aim for the left, right, and center.
Why Measure From Different Points?
Over time, the size and shape of a building can start to shift. This may be due to its settling, changes in temperature and humidity, or several other reasons. Measuring from different locations can give you the smallest size you will need to match. This ensures that your window will fit properly in the space provided.
In some cases, you may find an extreme shifting of size from one area to another. This can even put pressure on the window and increase its likelihood of shattering from smaller impacts. Adjusting the window before fitting the pane or even opting for custom windows can reduce these risks.
Modifying Window Measurements for Hardware Mounting
If you plan to install items like window screens or storm windows, adjust your notes to fit. This will not always be the case, though, so check with a professional if you are unsure if your hardware will impact the sizes you write down.
Measure the exact size of the hardware you wish to install, as well as the amount it will shift the window by. If the window needs to fit within it, then adjust your noted distances by this amount. Keep hold of the original notes, though, in case you find other solutions later.
Correct Window Measurement Notation
When writing down window sizes, always write it down as width first, then height. Or, if you want to be even more thorough, separate them in your writing, such as:
Width: X mm
Height: X mm
…where “X” is the measurement.
Also, make sure to specify the unit you used. Note that measuring in inches and sixteenth will offer very different results from using millimeters. Do not switch between units, either, to avoid confusion and costly mistakes.
How to Check If the Window Is Level
Make sure to use a level tool to check if the sides are even, as well as a straight edge to find curves or other inconsistencies. Mark any areas you find on the window and also on any measurement recordings you can make. You or a hired professional can use these to ensure you get the best fit later.
Measuring Non-Rectangular Windows
The approach you take to ensure non-rectangular windows fit will need to differ depending on the specific space. You should note, though, that some of these may demand custom windows, as will many other uniquely shaped window spaces.
To check for the best fit, make sure to always measure the extremes in distance. For example, with arches, note down the width of their lowest point and how high they rise. With circular windows, measure their widest and narrowest diameters for accuracy.
Many such windows will demand professional advice, so it may be best to have an experienced installer on hand to perform this role for you.
Benefits of Calling in the Professionals
