When you’ve decided it’s time to replace your windows, one of the first big considerations you have to make for the new windows is size. This involves measuring the window in a few important areas so you can accurately communicate with your contractor and any other professionals assisting you. Here’s some basic information on why measuring accurately is important, plus how to measure three vital areas.

Why is it Important?

Getting measurements right down to the inch is important for a few reasons. For one, this is a precise industry – even a fraction of an inch difference in the size of your window space can turn a perfect window option into one that simply can’t be used. If you’ve already been through the process of purchasing your products and it turns out the measurements were wrong, even by a little, you could be on the hook for buying new windows all over again.

Not only does this waste money, it wastes time. Effective communication with your contractor and other pros is vital for any home remodeling project, allowing them to set the proper timelines and schedule out their labor appropriately.   If you have any doubts about your measurements, our professionals can come and take care of all of that for you so you don’t have to stress over getting everything just right.

Sizing Height

Within each of our measuring areas here, it’s important to remember the number three. Everything with window measurement is done in threes, from the areas measured to the number of times you measure each area.

The first area to be measured is the height of the window, which involves measuring from the bottom ledge (the sill) to the lining around the window frame (the head jamb). Again, we start in threes here: First measure the furthest left side, then the center, and finally the furthest right side. Once you have all three numbers collected, take the smallest one and label it as a rough opening height.

Sizing Length

To ascertain the length of the window, the goal is to find the widest point of the frame possible. Take one measurement from the bottom, one in the center (at the meeting of the sashes) and one at the top, opening the window for accuracy if needed. Like with height, you’re keeping only the smallest of the three numbers you collect, labeling this rough opening width.

Sizing Depth

Don’t forget about depth, another vital factor in window size. Simply take a tape measure and run it from the outer edge of the frame to the innermost part of the window. Again, look for three different locations to do this in – exactly where is your choice. And again, take the smallest measurement of the three as your final number.
