Arch Small Window Shade Curtains Half Circle Moon Pleated Blinds (Jlong, Black, 24×12)

Best for compact arches and quick redecorating: This half-circle pleated fabric blind installs without tools using a simple peel-and-stick method. It fits most windows, including arched or square shapes, and provides dustproof, durable material that filters light while maintaining privacy. Suitable for bedrooms or entryways where a fast, non-permanent solution is desired. Caution: Stick-on methods may not hold as securely on glossy or very dusty frames.
Arch Window Shade Curtains Half Circle Moon Pleated Blinds (Jlong, White, 36×18)

Best for medium to larger arched windows: The white version offers similar easy installation and privacy features with a larger footprint. Made from non-woven fabric, it provides light filtration and UV protection to reduce glare and furniture fading. Ideal for living rooms or kitchens where a semi-private vibe is preferred without a blackout effect. Limitation: Slightly larger size may require trimming for non-standard arches.
Arch Window Shade Radius 18 Inch, Half Circle (Maritown)

Best for precise 18″ arches with strong adhesion: This shade uses a double-sided adhesive to secure the arc to the window, reducing tilt risk. Made from thickened non-woven fabric that filters 40–60% of light while keeping heat out and preserving privacy. Choose this if you have a defined 18″ radius arch and want a tool-free installation that stays put. Limitation: Adhesive wear over time or on textured frames may reduce grip.
Arch Window Shade Radius 18″ Half Circle (Maritown)

Best for easy, cut-to-fit installation: Similar to the previous Maritown option, this shade provides a 18″ arch with strong adhesive. Its non-woven fabric filters light and shields privacy. Choose this if you want flexibility to trim without losing the arch shape. Caution: Ensure precise measurement to avoid over-cutting before installation.
Chicplaid 4 Pcs Arch Window Shade Radius 18 Inch

Best for multi-window setups or bulk value: This pack includes four half-moon shades designed for arch windows. Each shade uses thickened non-woven fabric that filters 40–60% of light and provides privacy while helping control heat. Good for homes with several arched or front-door windows. Limitation: The bulk pack is best when all windows share the same radius and size; mismatched arches may require trimming.
Buying Guide: How To Choose The Right Arch Window Shade
What to consider before buying:
- Window shape and radius: Ensure the product fits an 18″ radius or your specific arch diameter. Some shades are pre-cut for 18″ arches, others are adjustable with trimming.
- Installation method: Decide between peel-and-stick, adhesive-backed, or reusable hooks. For rental homes, non-permanent options reduce wall damage.
- Light control and privacy: If you want more privacy or stronger light filtration, choose blackout-capable or thicker non-woven fabrics. For decorative purposes, lighter fabrics may suffice.
- Maintenance: Non-woven fabrics are typically easier to clean; check if the shade is moisture resistant for kitchens or bathrooms.
- Number of windows: Bulk packs may offer a better per-window value if you have multiple arches in the same size.
How to measure for a half-circle shade:
- Measure the width of the window opening at the widest point.
- Measure the radius if the arch follows a circular curve; your shade should match or be trim-to-fit as allowed by the product.
- Check whether the shade attaches to the frame or to an arched accessory that then adheres to the window.
Practical tips for use:
- Clean windows before applying to improve adhesion.
- Carefully align the shade to avoid tilt or crooked installation.
- Trim carefully if the product allows cut-to-size, avoiding over-trimming.
- Keep a spare adhesive strip for reapplication if needed.
