Buying Guide
What size and radius should I measure?
Measure the arch radius and the window width. Most arched shades here fit radii from 6 to 36 inches. Check whether the product supports trimming to fit irregular shapes, and confirm the maximum width or height before ordering.
What installation method best suits my needs?
Consider cordless and no-drill options if you rent or want a clean look. Look for double-sided tape or fixed brackets for stability. Tool-free installation is ideal for quick setup and removal.
Blackout vs. light filtering
Choose blackout for complete darkness and enhanced privacy. Light-filtering options work well for rooms where you want some daylight while maintaining a soft, diffused glow.
Durability and maintenance
Non-woven fabrics with aluminum backing offer durable blackout performance. Verify whether the shade is easy to clean and resistant to sagging over time, especially in larger arches.
Color and aesthetics
Two-sided or two-color designs can impact the room’s look. White or neutral backsides may be preferable if you value consistency from inside and outside views.
