It’s designed for a 36″ radius half-moon window and can be cut to fit 6–24″ radii in some configurations. Choose this if you want a more insulated feel and plan to customize the radius for tight arches. Limitation: edge light leakage may occur if installed on non-half-round windows.

It’s trimmed-friendly and includes how-to-fit accessories to prevent tilting. This size is suited for smaller windows or secondary rooms. Caution: smaller radii may offer less privacy for highly reflective, bright environments.
Buying Guide
What size radius do you need? Measure the arc radius of your window. Half-round arches often require a 6″ to 36″ radius shade, and some products offer trim options to match non-standard radii. Consider the level of blackout you want: full blackout for bedrooms or media rooms, light filtering for living spaces and kitchens.
Material and durability
Look for non-woven fabric with a laminated aluminum foil for privacy and heat control. Cellular (honeycomb) shades add insulation, which can improve winter warmth and summer cooling. Durability matters for high-traffic rooms or rental spaces where maintenance is a priority.
Installation and compatibility
No-drill or tool-free options are ideal for rentals or quick swaps. Double-sided tape and brackets help secure the shade with minimal installation time. If trimming is needed, ensure you have accurate measurements and a steady hand to avoid miscuts that affect fit and light leakage.
Privacy, light control, and aesthetics
For bedrooms or private spaces, prioritize blackout and privacy features. For living areas, consider light-filtering options to reduce glare while preserving outdoor views. Colors and finishes should complement your décor; white shades blend easily with most interiors.
Maintenance and care
Choose shades that are easy to wipe clean and maintain. Avoid fabrics that attract heavy dust or are difficult to trim. Proper care extends the life of the shade and maintains a neat appearance over time.
