Arched windows add architectural character, natural light, and visual drama. Finding window coverings that actually fit those curves is where most homeowners hit a wall. Standard blinds are built for straight lines, not half-circles, eyebrows, or sweeping arches.
Custom solutions are the answer. With the right product and precise measurements, arched windows can be both beautiful and functional without compromising the design of your home.
(Might be worth noting that Blindsgalore can currently only cover perfect arches)
Understanding Your Arched Window Type
Arched windows are not one-size-fits-all. Identifying the exact shape is the first step toward choosing the right treatment.
Common arched window shapes include:
- Perfect arches: True semicircles with a consistent radius
- Half-circle or fan windows: Flat bottom with a curved top, often above doors
- Eyebrow windows: Shallow curves that extend wider than they are tall
- Quarter-circle windows: Typically installed in corners
- Palladian windows: A large central arch flanked by rectangular side windows
Many arched windows sit above rectangular windows as part of a single unit. In these cases, the goal is not only a proper fit but also visual continuity between both sections.

Cellular Shades for Arched and Curved Windows
Cellular shades are one of the most effective and popular solutions for arched windows. The pleated fabric naturally fans out to follow curves, creating a clean, built-in look.
Cellular shades for curved windows are custom-cut to match the exact shape of your arch. The honeycomb structure also adds insulation, which helps regulate temperature in rooms with large or high-set windows.
Stationary vs. Operable Arch Cellular Shades
Most cellular arch shades are stationary, meaning they stay in a fixed position. This works well because arched windows are often decorative and located high on the wall.
Operable arch systems are available for homeowners who want adjustable light control. These use specialized track designs that allow the shade to open and close along the curve of the window.
- For soft daylight and privacy, Blindsgalore Select Light Filtering Arch Cellular Shades offer a refined look with gentle light diffusion.
- For precise fit and smooth curves, Bali Perfect Arch Cellular Shades are engineered specifically for half-circle and fan-shaped windows.
Coordinating Arches With Rectangular Windows
When an arch sits above a standard window, coordination matters. Matching fabric color, pleat size, and light-control level between the arch and the rectangular shade below creates a unified, intentional look rather than a segmented one.
Shutters as a Custom Arch Window Treatment
Shutters provide one of the most striking solutions for arched windows. Because they are built frame by frame, shutters can follow the exact curve of the opening.
Arched shutters create a sunburst effect that highlights the window’s shape instead of hiding it. They are especially well-suited for traditional, Mediterranean, and transitional homes.
Options include fixed louvers for consistent light filtering, adjustable louvers for flexibility, and designs that either cover the entire window as one unit or separate the arch from the rectangular section below.
Woven Wood Shades for Fan and Arch Windows
Woven wood shades bring warmth and texture to arched windows. Natural materials like bamboo, reeds, and grasses filter light beautifully and soften strong architectural lines.
These shades are typically stationary in arched applications and work best when the goal is ambiance and diffused light rather than full privacy or darkness. They pair well with coastal, organic modern, and bohemian interiors.
Roman Shades for Combination Windows
Roman shades are usually applied to the rectangular portion of a window rather than the arch itself. In this approach, the arch remains uncovered as an architectural feature or is paired with a stationary fabric insert that matches the shade below.
This solution works well when the arch is high and primarily decorative, while the lower window handles privacy and light control.
How to Cover a Half-Circle Window Above a Door
Half-circle or fan windows above doors let in beautiful light but sit directly in sightlines, especially in entryways.
The most effective solutions include:
- Stationary cellular arch shades for clean, tailored coverage
- Custom shutters shaped to the curve
- Light-filtering fabrics that soften daylight without darkening the space
Because these windows are rarely opened or viewed through, stationary treatments are often the most practical and visually balanced choice.
Measuring Arched Windows Correctly
Accurate measurements are essential for arched window treatments.
For perfect arches:
- Measure the width at the widest point
- Measure the height from the base to the top of the curve
For half-circle windows:
- Measure the flat bottom edge across the diameter
- Measure from the midpoint of that line to the highest point of the curve
For eyebrow or specialty shapes:
- Create a paper or cardboard template that traces the exact curve
If the shape feels complex, design consultants can review your measurements before you order to ensure a precise fit.
Motorization for High and Hard-to-Reach Arches
Many arched windows are installed high on the wall or above staircases. Motorization removes the need for ladders or manual reach.
Motorized arch-compatible shades can be controlled by remote, wall switch, or smartphone app. Smart home integration allows for scheduled adjustments based on time of day or sunlight exposure.
This is especially useful for tall entryways, great rooms, and two-story spaces with arched glass.
Why Custom Matters for Arched Windows
Arched windows vary widely in curve, radius, and proportion. Even small differences affect fit.
Custom arched window treatments are built to exact dimensions so the fabric or frame follows the curve precisely. This eliminates gaps, uneven edges, and makeshift solutions that distract from the window’s design.
Free samples let you compare materials in your own lighting, and custom fabrication ensures your arched windows feel intentional, balanced, and complete.
FAQs
Standard horizontal blinds cannot bend, so they only work on the rectangular portion of combination windows. Cellular shades, shutters, and specialty arch products are designed specifically for curved openings.
Yes. Cellular shades are one of the best options for arched and curved windows. The fabric fans naturally follow the shape, and the honeycomb design adds insulation and light control.
Stationary cellular arch shades and custom shutters are the most common solutions. They fit the curve precisely and provide consistent light control without needing daily operation.
Installation is similar to standard window treatments, but arch shades typically mount at a single top point so the fabric can fan outward. Most homeowners install them successfully using the included instructions.
