How to Measure for Replacement Windows

One of the most important elements of any window replacement project is taking accurate measurements. Everyone has heard this adage: “Measure twice, cut once.” And the same applies to windows. You’ll want to ensure that you’re properly measuring your window openings before your replacement windows are ordered and fabrication begins.

Nothing is worse than receiving your new replacement windows only to find out that they don’t fit the way you want them to. Not only is this a costly mistake, but it’s one that will set your project back substantially, as you essentially must start over from step one. In this guide, we’ll review the important step of measuring for replacement windows so you can start your project off on the right note.

How to Measure a Window Opening

Measuring a window opening requires looking at three different dimensions: height, width, and depth. For each of these dimensions, you’ll want to take three different measurements. To measure the height, you’ll want to measure from the top of the window opening to the bottom at the left edge, center, and right edge. You may notice that these numbers vary a little bit as no window opening or home will be perfectly squared off. The number to make note of is the smallest of these numbers.

Then, you’ll want to repeat this process to measure the width. You’ll measure the window opening across the top edge, middle, and bottom edge of the house window, again taking the smallest number as your measurement. For the depth, you’ll just want to ensure that you have at least 3 inches of depth in your window opening for your new windows.

Measuring Every Single Window Opening

If you’re replacing multiple windows at your home, you’ll need to measure each window individually. Over the years, a house will settle, which can alter the measurements of your windows from room to room by a quarter of an inch or more.

Why does this matter? A window that’s too large for the opening won’t be able to be installed properly, especially if the structure of your home is concrete block or brick. Similarly, a window that’s too small can cause problems. While you may be able to fit it in the window opening, the wider gaps between the window and the opening will need to be filled in, which may reduce your ability to secure the window to your home or may reduce the performance capabilities of the window.

Once you have the heights and widths measured for each of the house windows you’re planning to replace, you’ll should submit these measurements to the window manufacturer. Window manufacturers will use these numbers and adjust them as necessary to provide you with the perfect-sized windows for your home.
