Arched windows can be hard to cover with standard blinds, and it is important to check how a shade actually operates before you buy. The options here are semicircular, cordless shades in several sizes, mostly designed to stay in place over an arch. MYshade says its included clips can also be used to adjust the fabric when the shade is installed on a regular window—not necessarily to raise and lower it while fitted to an arch. If you need an arch shade that opens and closes in place, confirm the operating method and fit with the seller before ordering.
Our comparison focuses on shape, light control, sizing, installation, and practical use. The choices include blackout cellular shades and a light-filtering pleated shade, so you can match the covering to your room and window.

Our Picks: Best Arch Window Blinds That Open And Close reviews
1. MYshade White Blackout Cellular Shade for Smaller Half-Round Windows
This white MYshade shade is a semicircular cellular covering listed at 24 inches wide by 12 inches high, with a 12-inch radius. Its honeycomb-style fabric and laminated foil layer are intended to block light and provide privacy. The cellular construction is also designed to help insulate the window, though the actual effect will depend on the window and how closely the shade fits.
Installation is described as an inside mount using supplied double-sided tape and hardware, without drilling. The listing says the material can be trimmed for an irregular arch, but careful measuring and cutting matter: trimming too much may leave gaps or an uneven curved edge. The shade is cordless and manually operated. The supplied clips are described for adjusting the fabric when the shade is reused on a regular window, so do not assume this is a lift-and-lower arch blind once installed over a half-round window.
Its compact size and white finish make it a straightforward option for a smaller arch where you want to reduce incoming light. Some users report that the material is manageable to cut and that it blocks light well. One limitation is that the listed size and radius range are specific; measure your window rather than relying on the product’s general “trim to fit” description.
Pros:
- Blackout construction for privacy and light reduction
- Cellular design intended to help with insulation
- No-drill installation method with supplied tape and hardware
- Can be trimmed for a closer fit to some irregular arches
Cons:
- Not described as a conventional adjustable arch blind after installation
- Limited to the listed smaller size and radius range
Verdict: Choose this white MYshade model if your arch is within its measurements and you want a small, blackout covering that stays mounted in place.
2. MYshade Gray Blackout Cellular Shade for a Larger Arch
This is the largest single-piece MYshade option in this group, listed at 48 inches wide by 24 inches high and intended for arches with radii from 6 to 24 inches. It uses a gray blackout cellular shade with a foil layer for light blocking and privacy. The larger format may suit a broad half-circle window, but it also makes accurate measurements especially important.
The listing describes an inside mount with double-sided tape and included mounting hardware. It also says the fabric can be trimmed, and includes clips for adjusting it when used on a regular window. As with the smaller MYshade sizes, the supplied operating details do not establish that the shade can be opened and closed while mounted on an arch. Its manual, cordless design should therefore be treated as a fixed arch covering unless the seller confirms otherwise.
Reported use of this MYshade style points to easy cutting and useful light reduction, and some users describe it as helping limit heat coming through the window. Those are practical advantages for a sunny room, but the product is still a fabric shade, not a guarantee of complete thermal sealing. Its gray color gives you an alternative to white, while the large size may be harder to trim neatly than a smaller panel.
Pros:
- Largest listed single-piece option among these picks
- Blackout cellular fabric with a foil layer
- Gray finish offers an alternative to white
- Can be trimmed to suit some nonstandard arches
Cons:
- Large panel requires careful handling and precise cutting
- Arch-mounted opening and closing are not clearly specified
Verdict: This is the MYshade option to consider for a large arch when blackout coverage matters more than operating the shade up and down.
3. MYshade Gray Blackout Cellular Shade Two-Pack
This MYshade listing is a two-piece set in gray, with each piece listed at 36 inches wide by 18 inches high. The semicircular cellular fabric is designed to block light, offer privacy, and help reduce heat transfer. A pair can be useful if you have two windows of the same size, but check the listing dimensions and quantity carefully to make sure the set matches your project.
Like the other MYshade options, this shade is cordless and uses a no-drill installation approach with double-sided tape and mounting hardware. The fabric is described as trimmable, which can help with a slightly irregular arch, but cutting two pieces consistently takes care. The included clips are described for opening and closing the shade when it is used on a regular window; the information does not confirm an operating mechanism for an arch installation.
Some users report that this style is fairly easy to cut and install and works well for reducing light. A two-piece pack may be more convenient than buying separate panels for matching windows, but it is less flexible if you need only one shade or have two different window sizes. Compare the width, height, and curve of each arch before ordering.
Pros:
- Two pieces included for matching windows
- Blackout cellular design for privacy and light reduction
- Gray color and cordless construction
- Trimmable fabric may accommodate some fit differences
Cons:
- Both windows need to suit the listed size for the set to be useful
- Does not clearly offer open-and-close operation when installed on an arch
Verdict: Pick this two-pack if you need two similar-sized gray blackout coverings and are comfortable measuring and trimming both pieces.
4. MYshade Gray Blackout Cellular Shade for a Compact Arch
This gray MYshade model shares the compact 24-by-12-inch format and 12-inch radius range of the white version. It is a blackout cellular shade with a foil layer, intended to cover a half-round window and provide privacy. The material and basic design are similar to the other MYshade picks, so the main choice here is its color and whether its dimensions suit your window.
The shade is listed as cordless and manually operated, with an inside mount and supplied double-sided tape and hardware. The listing also includes clips and describes adjusting the fabric when the shade is used on a regular window. That is different from a standard arch shade that can be raised and lowered in place, so confirm the operation before buying if adjustability on the arch is essential to you.
Its small size should be more manageable to position and trim than the larger panel options, but it still needs a careful fit to avoid light gaps around the curve. The gray fabric can be a better visual match for some rooms than the white version. The product information does not provide a specific sound-reduction measure, so treat the cellular structure’s noise-reduction description as a design aim rather than a guaranteed result.
Pros:
- Compact size for smaller half-round windows
- Blackout fabric intended to provide privacy
- Gray finish and cordless design
- Includes mounting supplies and clips
Cons:
- Size may not suit wider or taller arches
- Not clearly designed to open and close while mounted over an arch
Verdict: Choose this model over the white version if you want the same compact blackout format in gray and your measurements fall within its fit range.
5. Jlong Light-Filtering Pleated Shade for Softer Daylight
The Jlong shade is a white, semicircular pleated covering listed at 36 inches wide by 18 inches high. Unlike the MYshade blackout options, it is designed to filter strong light rather than block it completely. That makes it a better fit for a room where you want softer daylight and some privacy without fully darkening the window.
The non-woven fabric is described as dust-resistant and easy to spot clean. Installation uses adhesive tape, with no tools required according to the listing. It can be cut to size, but the instructions call for measuring the window’s radius and length before ordering. Cutting is permanent, so plan the curve and width carefully before trimming.
This is the only light-filtering choice in the group, which gives it a different purpose rather than making it a direct substitute for a blackout shade. The product information lists manual operation but does not explain a mechanism for opening and closing the arch-mounted shade. It may suit a fixed covering where some daylight is welcome, but it is not the clearest pick if you need a movable arch blind.
Pros:
- Light-filtering fabric preserves more daylight than blackout options
- No-tool adhesive installation
- Can be cut to fit a range of window shapes
- Spot-clean care instructions
Cons:
- Not intended to provide blackout coverage
- Opening and closing while mounted on an arch are not specified
Verdict: Consider the Jlong shade if you prefer filtered daylight and a simple pleated look over full light blockage.
How to Choose Arch Window Blinds That Open and Close
Confirm How the Shade Operates on an Arch
Do not rely on “manual” or “cordless” alone to tell you whether a shade opens and closes in place. In these product listings, MYshade describes clips for adjusting the fabric when it is used on a regular window, but does not clearly describe a lift mechanism for the arch installation. If you want to uncover the arch for daylight, ask the seller whether the shade can be moved while mounted in its intended position. A fixed shade may work well for privacy or light control, but it is not the same as an operable blind.
Measure the Window’s Width, Height, and Curve
Measure the full width at the bottom of the arch and the height from that point to the top of the curve. Also check the arch radius if the product specifies one. Compare those measurements with the listed size and fit range before ordering. “Can be trimmed” does not mean every shade will fit every arch, and trimming cannot add fabric if the panel is too small.
Choose Blackout or Light Filtering
Blackout cellular shades are the better match when your main goals are blocking light and improving privacy. The Jlong pleated shade filters light instead, so it can keep a room brighter while softening direct sun. Think about the room’s use: a bedroom may benefit from more blockage, while a living space may be more comfortable with filtered daylight.
Consider the Material and Construction
The MYshade options use cellular fabric with a foil layer, while the Jlong option uses non-woven pleated fabric. Cellular construction is intended to help with insulation, and the Jlong fabric is described as dust-resistant and spot-cleanable. Treat performance descriptions as product claims, not guarantees; fit, window construction, and installation can affect the result.
Check the Installation Method and Your Window Frame
The MYshade models use double-sided tape and supplied mounting hardware, while the Jlong listing describes adhesive installation without tools. Before you choose an adhesive-mounted shade, make sure the surface is clean, suitable for tape, and large enough for the planned mounting area. If you are unsure whether the adhesive will hold on your frame, ask the manufacturer before installation.
Match the Pack Quantity and Color to Your Project
Check whether the listing is for one shade or a set. The MYshade 36-by-18-inch listing is a two-piece set, while the other listed MYshade sizes are single pieces. A pair is useful only if both windows suit the same dimensions. Color matters too: the smaller MYshade options come in white or gray, while the larger options shown here are gray.
Frequently Asked Questions
Do these arch shades open and close after installation?
The product details do not clearly confirm that the arch-mounted shades can be raised or lowered in place. MYshade describes clips for adjusting the fabric when it is reused on a regular window. If you need a movable shade on the arch itself, verify that feature with the seller before ordering.
Are the MYshade options blackout?
Yes. The listed MYshade models are described as blackout shades, with a foil layer intended to block light and provide privacy. A close fit is still important, since gaps around the shade can let light through.
What is the difference between the Jlong shade and the MYshade shades?
The Jlong model is a light-filtering pleated shade. The MYshade options use cellular fabric and are described as blackout. Choose based on whether you want to soften daylight or block more of it.
Can I trim an arch shade to fit my window?
The MYshade and Jlong listings describe trimmable fabric. Measure first and cut cautiously, since trimming is permanent and an uneven curve can leave gaps. Confirm that your window falls within the product’s stated size and radius range before modifying the shade.
Do these shades require drilling?
The listings describe adhesive or double-sided tape installation and include mounting supplies. The Jlong listing says no tools are required. Check the included instructions and make sure your mounting surface is suitable before installing.
Which option is best for a larger arch?
The 48-by-24-inch MYshade is the largest single-piece option listed here and is described for arches with radii up to 24 inches. Still, compare your window measurements with the full product dimensions and confirm the fit before purchase.
Which shade should I choose if I want daylight to come through?
The Jlong pleated shade is the light-filtering option in this group. It is intended to soften strong sunlight rather than create blackout conditions.
Final Recommendation
For an arch that needs strong light blockage, the MYshade cellular options offer the clearest choice, with sizes for smaller windows, larger arches, and a two-piece set. The Jlong shade is a better match if you want light filtering instead of blackout coverage. However, if your main requirement is an arch blind that opens and closes while mounted, confirm the operating mechanism before buying: the supplied product details do not clearly establish that these shades move in place on an arch.
