How to Measure Windows in 3 Easy Steps

Measure Your Window’s Width

Measure the horizontal distance from the inside of one side jamb (the side of the frame) to the other. If you have a wooden frame that you believe may be warped, repeat this measurement three times: once at the top, once in the middle, and once at the bottom. Record the shortest measurement of the three.

Measure Your Window’s Height

Measure your window from the top of the frame to the window sill. As with the width, if you have a warped wooden frame, do this three times: once on the left side of the window, once in the middle, and once on the right side. Record the smallest measurement. Remember to always list the width of your dimensions before the height.

Calculate Your Window’s United Inches

Converting to united inches makes it easier to get estimates. United inches, different from square inches, are used in the window industry to ensure window frames are correctly priced. Calculating them is easy. Simply add together your window’s width and height. For example, a width of 30” and a height of 50” would be 80 united inches.
