How to Measure
Your Windows
Getting the right measurement is the most important step. Follow our guide and your custom shades will fit perfectly — guaranteed.
Step 1: Choose Your Mount Type
Step 2: Measure for Inside Mount
1
Measure Width
- Measure the inside width of the window opening in 3 places: top, middle, and bottom.
- Use the SMALLEST measurement for your order.
- We'll deduct 3/8" automatically for a perfect fit.
Always measure in inches to the nearest 1/8".
2
Measure Height
- Measure from the top of the window opening straight down to the sill.
- Measure in 3 places: left, center, and right.
- Use the LONGEST measurement for your order.
For valances, add 2–3" to your height measurement.
3
Check Depth
- Measure the depth of the window frame (how deep the recess is).
- Most standard shades require at least 2" of depth.
- Motorized shades require 3" minimum depth.
Not enough depth? Use outside mount instead.

Common Mistakes to Avoid
Don't round to the nearest inch
Always measure to the nearest 1/8". A 1/4" difference can mean your shade won't fit.
Measure multiple times
Windows aren't always perfectly square. Measure in 3 places and use the smallest width / largest height.
Account for obstructions
Check for window cranks, handles, or locks that the shade might hit when lowered.
Check the deduction
For inside mounts, we automatically deduct 3/8" from your width for proper fit. Don't deduct it yourself.
