Measure Width and Length Correctly

Shades can be inside or outside mounted. Considering the window frame depth is the first step.

Inside Mount Stack Height
  • A clean, built-in look, 2 1/2 inches minimum depth requirement;
  • 3/8 inch headrail deduction taken at your actual measuring to ensure the side does not touch the edges tightly;
  • Note there will be slight gaps on the sides due to fabric deductions.
Outside Mount Stack Height
  • No minimum depth requirement.
  • We recommend ordering additional width 4-6 inches to prevent light gaps on the sides of your window.
Cordless System
  • Easy Operation: Smooth, intuitive control, just push or pull to adjust.
  • Durability: High-quality build, tested for 30,000 lifts. No lag, no wear, just steady performance.
Stack Height

The stack height will vary slightly based on the size of the Roman blinds as well as the fold type. The stack height will vary from 9 inches to 14 inches, with taller shades having a larger stack height.
