How to Measure Blinds for a Perfect Fit
Whether replacing old window treatments or needing the perfect blinds for a new home, accurate measurements are essential. There’s no standard or universal size for windows, so when you visit a window treatment showroom, a team member will ask what size you’re looking for. Knowing what to tell them can help both parties.

Our skilled Window Decor of Fairfax team compiled this guide to help you learn how to get a rough estimate of your window size.
Why Measuring Your Windows Matters
Measuring your windows efficiently when investing in new coverings, like blinds, ensures a snug fit. Accurate measurements also help you enjoy the various benefits of having window blinds, including fantastic light and privacy control.
If you don’t measure your windows, when installed, they may not cover the window adequately, allowing light to seep in when you don’t want it and frustrating you.
How to Measure for Blinds
If you’re curious about how to measure for blinds, here are a few steps for inside and outside mounting options:
Measuring Windows for Mounting Blinds Inside
Use the following three steps to measure your windows if you’re mounting your blinds inside the frame:
- Use a tape measure to take measurements in three places: across the top, middle, and bottom.
- Measure the window’s height on the left, right, and middle. Note the longest measurement of the three.
- Measure the window’s depth.
Measuring Windows for Mounting Blinds Outside
Here are a couple of steps for measuring windows where you’re mounting your blinds outside the frame:
- Measure the window's width and height.
- Add a few extra inches to your findings above to enhance light and privacy control.
