We’ve written in the past about how there’s really no such thing as a “standard” window size. But there are common window sizes and knowing what they are can help you estimate your needs and budget when either replacing existing windows or building a new home.
Common Window Sizes
Most single and double-hung windows in homes range in width from 24 to 30 inches and in height from 48 to 56 inches. Most building codes have minimum window requirements for habitable rooms:
- 20-inch width
- 24-inch height
- 44-inch maximum from bottom of window opening to floor
Other codes you may be required to meet include safety glass installation for sliding doors, sidelights, windows near doors, and glass that’s less than a minimum distance from the floor.
So, what is a “common” size window? It depends on:
- The window’s rough opening. This is the measurement from the inside of one side of the frame to the inside of the other side. If you want to calculate this measurement yourself, measure the top, middle, and bottom of the window horizontally and then do it again vertically.
- The half inch rule. Once you calculate the rough opening, take a half-inch off each measurement to allow for installation of flashing.
- Double-hung window sizes. One of the most common widow types, these windows come in 24, 28, 32, and 40-inch sizes. Heights include 36, 44, 52, 54, 62, and 72 inches. Don’t forget to take a half-inch off of each measurement.
- Sliding windows. Horizontal options include 36, 48, 60, 72, and 84 inches and vertical possibilities are 24, 36, 48, and 60 inches.
For calculation and budgets purposes, keep in mind that window measurements are first given in width then height. And even though window sizes differ, the measuring technique is the same for all of them.
