Inside mount
Sits inside the window frame for a clean, built-in look. Your frame needs enough depth.

Before you measure
Use a metal tape measure
Cloth and plastic tapes stretch, so the numbers can be off.
Measure to the nearest 1/8"
Write down the exact number. If you have to round, round down.
Check the window depth
Inside mounts need a minimum depth for the brackets. Each guide lists it.
Don’t make deductions
Give us the actual size of the opening. We adjust the shade so it fits and moves freely.
