Ordered Width = Window Casing Width - 3/8 inches
- A clean, built-in look, 2 1/2 inches minimum depth requirement.
- Deduct 3/8 inches from your window casing width to ensure the shades fit inside the frame.
- Note there will be a slight gap (approx. 1/4 inches on each side) to allow for smooth operation.
Ordered Width = Window Casing Width + 2~4 inches
- No minimum depth requirement.
- We recommend adding additional width 2-4 inches to prevent light gaps on the sides of your window.
- We recommend installing the shades 4-6 inches above the frame, allowing window exposure when shades are up.
