Frequently Asked Questions

What is the difference between inside and outside mount?

An inside-mount blind fits within the window frame, so it is ordered slightly smaller than the exact opening for clearance. An outside-mount blind is attached to the wall or trim around the window, so it is ordered larger than the opening to overlap and block light gaps.
