Shopping for window blinds can seem like a guessing game. How do you know which sizes you need and what do you do if you can’t find the right size? Knowing the standard blind sizes can help you make the right choice for your home.

There are forty-eight different standard sizes of blinds based on length, width, and depth. Read on to learn more about these standard sizes and what to do if they won’t fit your windows.


Window blind length refers to the height of your window from top to bottom. Having the right blind length can help you avoid either having a gap at the bottom of your window or a pile of slats laying on the sill. Some blinds allow you to remove excess slats, so if you have to choose between too long or too short, you’ll want to err on the side of too long.

There are four basic blind lengths: 36 inches, 48 inches, 60 inches, and 72 inches. 36- and 48-inch blinds will most commonly fit in partial wall windows. 60- and 72-inch blinds will be more common in full-length windows or sliding glass doors.


Your window blind width refers to the measurement of your window from side to side. If your blinds are slightly too wide, you may be able to cut them down to size, but you should never get blinds that are too narrow. If you live in an old home with non-standard windows, this may be the best option for you to get blinds that fit.

There are also four standard blind widths: 24 inches, 36 inches, 48 inches, and 60 inches. You’re likely to see 24- and 36-inch widths paired with the smaller heights or with accent windows. The 48- and 60-inch blinds will show up more often in short, wide windows or in full-wall windows.


Your window blinds also have a third measurement: the depth. This refers to how tall each individual slat is when the windows are closed. Blinds that are too deep can bump into the window or extend too far past the window frame and cause problems.

Most blinds are either half an inch, an inch, or two inches deep. When selecting a blind depth, remember that the larger the slats, the heavier the blinds. If you’re getting wider slats, you may need to use a lighter-weight material to offset the additional weight.
