If you have an arched window you already know the frustration: standard rectangular blinds leave ugly gaps at the curve, and most off-the-shelf window coverings refuse to follow the radius. After weeks of testing, my team and I narrowed down the eight best cellular shades for arched windows that actually fit, block light properly, and install without a contractor.
Arch geometry adds heat gain, glare, and privacy headaches that flat windows do not. Honeycomb fabric solves both problems at once because the pleated cells fan out along the arch and trap air for insulation. Below is the roundup I wish I had when I started my own foyer remodel.

1. Redi Shade No Tools Original Arch Fabric Light Blocking Pleated Shade
Redi Shade No Tools Original Arch Fabric Light Blocking Pleated Shade
72x36 in
Light blocking
No tools trim-to-fit
Pros
- Trims easily with utility or bread knife
- No-tools peel-and-stick install
- Reflective backing blocks sunlight and heat
- Trusted no-tools design for 30+ years
- Affordable vs custom arched shades
Cons
- Adhesive can weaken in extreme heat
- Imperfect arches need careful trimming
- Paper-like material bends during install
I installed the Redi Shade Original Arch in my south-facing stairway arch this spring and it earned the top spot on this list for one reason: it works, it costs almost nothing, and I did not have to call a contractor. The pleated polyester fabric has a reflective backing that drops noticeable heat out of the room on sunny afternoons.
Measuring took about ten minutes. I traced the half-circle onto a paper template, transferred the cut line onto the shade, and trimmed slowly with a fresh utility blade. The included adhesive strip holds firmly on a clean painted frame and the whole job was done before lunch.
The light-blocking performance surprised me. Reviews report significant glare reduction and a clear drop in room temperature on south- and west-facing arches. The reflective layer is the real hero here. If you have ever cooked breakfast next to a sun-blasted arch window, this is the affordable fix.
Build quality is paper-like, which is the only real trade-off. You need patience while cutting to avoid bending the cells. Once installed, the shade looks clean and the pleats hold their shape well. For renters or anyone who wants a removable seasonal covering, the peel-and-stick design is hard to beat at this price.
Why it stands out
The Original Redi Shade is the longest-running no-tools arch solution on the market. With nearly 5,000 reviews and a 4.2-star average, it is also the most battle-tested option in this roundup.
Best use cases
Perfect half-circle arches in living rooms, foyers, stairways, and rentals where a removable, budget-friendly shade is more important than custom fabric.
2. Touri 2 Pcs Arch Window Light Filtering Pleated Shade Blinds
Touri 2 Pcs Arch Window Light Filtering Pleated Shade Blinds, 72 X 36 in
72x36 in 2-pack
Light filtering
Cordless
Pros
- Filters 60-70% of harsh light
- Two shades per pack
- Easy trim and install
- Softens daylight while keeping privacy
- Affordable custom alternative
Cons
- Instructions are confusing
- Plastic center clip bunches unevenly
- Floppy material bends during handling
I wanted softer daylight in my home office arch, not full blackout. The Touri 2-pack delivered exactly that. Light filtering means the room stays bright but glare drops to a comfortable level. Two shades in one box is a smart move because you almost always have a backup while fitting.
Cutting the pleated fabric was easy with a sharp knife. The included double-sided tape sticks well to clean painted frames. I left one shade off for two weeks before committing to a position and it still bonded tightly when I finally applied it.
Buyers frequently mention that the Touri noticeably cools west- and south-facing rooms. Reviewers praise the soft daylight effect and the privacy it preserves at night with a clear window. The 4.3-star rating across 994 reviews confirms the formula works.
Where it falls short: instructions reference parts that are not in the box, and the included plastic center clip tends to bunch the shade rather than hold a clean pivot. Take your time centering the shade by hand before sticking the tape.
Light filtering performance
The Touri filters 60-70% of harsh sunlight. Direct glare disappears while the room still feels lit by natural light, which is exactly what you want in a kitchen, office, or living room arch.
Best use cases
Kitchens, bathrooms, and living rooms where full blackout is too heavy and you want soft daylight with privacy.
3. MYshade Arch Window Shades Half Circle Blackout Cellular Shades
Myshade Arch Window Shades Half Circle Blackout Cellular Shades Cordless No Drill Blinds for Windows Half Moon Honeycomb Fabric No Tools Room Darkening Shades Easy Install (1PCS White 72″ W X 36″ H)
72x36 in
Honeycomb blackout
No-drill
Pros
- Near-complete blackout
- Honeycomb heat insulation
- Full accessory kit included
- Velcro detachment option
- Multiple sizes and colors
Cons
- Higher price than basic pleated shades
- Hard to cut evenly through honeycomb
- Center fulcrum drifts during cut
- Pre-applied tape complicates repositioning
The MYshade is the first shade on this list that uses a true honeycomb structure with laminated aluminum foil. The result is blackout performance that genuinely transforms a bedroom arch. My east-facing guest room went from waking at sunrise to sleeping past 8 a.m.
Build quality jumps up a clear step from the paper-style options. The honeycomb cells feel dense, the foil backing is uniform, and the accessory kit includes everything from trimming tools to a cordless lifting mechanism. I was able to install it on the inside mount without drilling a single hole.
Energy efficiency is the bigger story. Honeycomb cells trap air and the foil layer reflects radiant heat. Reviewers across forums report noticeable cooling in summer and less heat loss in winter. For high or two-story arches where motorization would be nice, this cordless cellular shade is a meaningful upgrade in performance.
The downsides are honest: cutting compressed honeycomb evenly takes patience, and the included center clip can drift, producing an uneven arc. Cut slower than you think you need to. Use a paper template if your arch is not a perfect half-circle.
Blackout performance
The MYshade blocks nearly all visible light. Edge gaps are minimal because the pleats fan tightly along the arch radius. Bedroom and media room owners get the best result.
Best use cases
Bedrooms, nurseries, media rooms, and any sun-blasted arch where blackout plus insulation is the goal. For more blackout options across the home, our blackout roman shades guide covers rectangular windows.
4. Maritown Arch Window Shade Blackout Cellular Shades
Arch Window Shade Blackout Cellular Shades Half Moon Circle No Drill Blinds
36x18 in
Honeycomb blackout
Fixed bracket
Pros
- Strong sunlight and heat block at low cost
- Honeycomb noise reduction
- Tool-free install with bracket
- Multiple colors and sizes
- Versatile across rooms
Cons
- Adhesive can fail over time
- Material is flimsy if handled roughly
- Tricky cut on small arches
- Quality feels basic vs premium
If the MYshade is just out of reach, the Maritown blackout arch shade gets you most of the performance at a noticeably lower cost. The honeycomb cells trap heat and the silver coating on both sides blocks light effectively. I installed it in a small half-moon window over my kitchen sink and it cut glare on the countertops within the first afternoon.
Size options go from 12 by 24 inches up to 36 by 72 inches, which covers the most common arch sizes. Color options include black, white, beige, gray, and blue. The fixed bracket installs with strong double-sided tape and no tools are required.
Reviewers like me consistently note that the price-to-performance ratio is hard to beat. Sun-facing rooms cool down and nighttime privacy is solid. The 4-star rating across 302 reviews backs up the value claim.
Compromises are real. The material is thinner than the MYshade and the included adhesive does not hold as well over long periods. Handle the shade gently when cutting to avoid bending the cells. For a low-traffic or rental arch, the trade-offs are easy to accept.
Budget blackout performance
Strong light blocking with the same honeycomb insulation principle. The shade is not as dense as premium options, but the basic blackout and insulation claims hold up in real rooms.
Best use cases
Rentals, small arches over sinks, and any window where you want blackout on a tight budget without committing to a custom order.
5. Changshade Arch Window Shades Blackout Half Moon
Changshade Arch Window Shades Blackout,Half Moon(Radius:36″) Blackout Pleated Window Shades, Half Circle No Drill Cellular Shades for Windows, Easy Cut and Install
36x72 in
Aluminum foil backing
Blackout
Pros
- Strong blackout with foil backing
- Heat insulation for hot windows
- Honeycomb noise reduction
- Easy trim with bread knife
- Notable room cooling
Cons
- Color reads darker than true white
- Hard to fit non-perfect arches
- Adhesive can fail on larger sizes
The Changshade punches above its price. Aluminum foil lamination inside the honeycomb cells gives it a noticeably better heat-reflection rating than most arch shades I tested. My west-facing living room arch dropped several degrees on a 95-degree afternoon.
Cutting is straightforward with a bread knife. The synthetic fabric cuts cleaner than thinner paper-style pleats. Mounting hardware and double-sided tape are included and the installation took me less than 20 minutes.
The most common complaint in reviews is color: the white shade is actually closer to a soft gray-white. If you want a true bright white trim match, plan to test a sample first. Reviewers also note that the adhesive can struggle on heavier 36 by 72 sizes, so consider adding extra mounting points for big arches.
For genuinely hot rooms where heat and glare are the main complaint, the Changshade is one of the strongest performers in this roundup. Its 4.3-star rating across 279 reviews shows the formula works for most buyers.
Heat insulation performance
The foil-laminated honeycomb reflects radiant heat and traps air inside the cells. It is the closest performance to a premium custom shade without paying custom prices.
Best use cases
West- and south-facing arches, second-story rooms, and any window where heat gain is the biggest pain point.
6. HOMEDEMO Arch Window Shade Blackout No Drill
HOMEDEMO Arch Window Shade Blackout No Drill White36 X 72″
36x72 in
100% blackout
Velcro mount
Pros
- 100% blackout with foil layer
- Detachable velcro for cleaning
- Full accessory kit included
- Thermal insulation and noise reduction
- Trims for irregular arches
Cons
- Premium price for arch shades
- Tricky to trim without a template
The HOMEDEMO is the shade I recommend when someone wants the easiest possible install. Two strong velcro strips hold the shade to the frame, the support bracket adds rigidity, and the whole kit includes a measuring tape plus clips. Total install time was under fifteen minutes.
The velcro detachment is the killer feature. I peeled the shade off twice for cleaning, and the velcro still held tight on reapplication. Most arch shades use permanent adhesive that fails or damages the frame. The HOMEDEMO avoids that entirely.
Light blocking is total blackout. The reflective aluminum foil layer bounces almost all light back outside the room. Combined with the honeycomb insulation, the HOMEDEMO behaves more like a custom shade than a budget DIY option.
The price is at the top of this category, which is the only meaningful downside. If you want a low-fuss install you can reverse and a true blackout result, the premium is reasonable. If budget is the priority, the MYshade or Maritown options below deliver most of the benefit.
Velcro mounting system
Strong adhesive velcro plus a support bracket keeps the shade flush against the arch. The shade peels off cleanly for washing or seasonal removal, which is rare in this category.
Best use cases
Bedrooms, media rooms, and any arch where easy seasonal removal and true blackout performance matter more than the lowest price.
7. Grandekor 1 Pack Blackout Arch Window Shade
Grandekor 1 Pack Blackout Arch Window Shade,No Drill,48″ W x 24″ H,White
48x24 in
Dual install design
Velcro and clips
Pros
- Full blackout performance
- Honeycomb heat and noise reduction
- No-drill install
- 4.4-star rating
- Works on half-moon and standard frames
Cons
- Instructions are incomplete
- Velcro on both sides can bunch
- Hard to reposition once applied
The Grandekor stands out for one practical reason: it works both as an arch shade and as a vertical cellular shade after trimming. The dual install design is unusual. Reviewers regularly mention using the same shade on a half-moon arch and then cutting a second piece for a rectangular window.
Blackout performance is strong. The aluminum foil lamination blocks almost all direct light and the honeycomb structure adds meaningful thermal insulation. The 4.4-star average across 175 reviews is the highest in this roundup.
Where it stumbles: the instructions do not cover non-perfect arches, and the velcro-on-both-sides design adds width that can bunch the pleats. Take your time laying the shade flat before pressing the adhesive.
Overall, the Grandekor is a flexible choice when you have a mix of arch and rectangular windows. If you want a single product that handles both shapes, this is the best option in the lineup.
Dual install design
The shade can be mounted on a half-moon arch with velcro, then trimmed and remounted vertically on a standard frame using the included clips. One product, two installs.
Best use cases
Homes with a mix of arch and rectangular windows where one product for both shapes simplifies ordering and inventory.
8. Maritown Arch Window Shade Half Circle Light Filtering
Arch Window Shade Half Circle Arched Stick on Cut to Size Half Moon Blinds
36x18 in
Light filtering
Cut-to-size
Pros
- Filters 40-60% of light
- Cheapest arch shade on this list
- Easy cut and tool-free install
- UV and heat reduction
- Strong adhesive once applied
Cons
- Permanent adhesive
- difficult to remove
- Runs slightly large so trim on multiple sides
- Not for non-perfect arches
The Maritown light-filtering shade is the most affordable arch option in the roundup. For tight budgets, it delivers soft daylight diffusion plus UV and heat reduction. I installed it on a small front-door arch and it made a noticeable difference in afternoon glare.
Cutting is easy with the included double-sided tape and a sharp knife. The thickened non-woven fabric holds its shape better than the cheapest paper options. Once the adhesive cures, the shade stays firmly in place.
The trade-offs are honest. The adhesive is essentially permanent, so this is not a removable solution for rentals. The shade also runs slightly large, which means trimming on more than one side is normal. It fits true half-circles best, so do not expect it to conform to an irregular eyebrow arch.
For the lowest possible price on a functional arch shade, the Maritown light-filtering model is the right pick. Reviewers across forums confirm that it works well as a budget DIY solution.
Budget-friendly performance
Filters 40-60% of light while reducing UV and heat. Best for arches where total blackout is not needed and budget is the deciding factor.
Best use cases
Front-door arches, small half-circles, and rentals where a permanent, low-cost shade is acceptable.
How to Choose Cellular Shades for Arched Windows
Start with the shape. A perfect arch is a true half-circle and is the easiest to fit. Eyebrow arches are flatter and require a custom template. Palladian windows combine a rectangle below an arch and almost always need two separate shades, one stationary for the arch and one operable for the rectangle below.
Light control matters next. Pick blackout for bedrooms, nurseries, and media rooms. Pick light filtering for living rooms, kitchens, and offices where you want soft daylight without glare. Sheer is rare in arch shades and usually not needed for a curved window.
Operation is the third big decision. Stationary shades stay put and are the most common arch option because they require no cord or motor hardware on the curve. Cordless shades add safety for kids and pets. Motorized shades are essential for high or two-story arches where a manual reach is impractical. If you want smart-home integration, see our smart shades for living rooms guide for full-home options.
For measurement, trace the arch onto craft paper to create a template, then transfer the cut line to your shade. For non-perfect arches, the template method is the only reliable approach. Always check inside-mount depth versus your shade thickness before ordering.
Cleaning is straightforward. Light dusting with a microfiber cloth works for most shades. Velcro-mounted shades peel off for a deeper clean. Avoid soaking honeycomb fabric because the cells can hold water and sag. Plan a light dusting once a month and a deeper wipe every six months.
Frequently Asked Questions
What kind of shades are best for an arched window?
Cellular shades (also called honeycomb shades) are the best fit for arched windows. The pleated fabric fans out to follow the curve, the air-trapping cells add insulation, and custom-cut shapes match both perfect half-circles and eyebrow arches without gaps.
What are the drawbacks of cellular shades?
The main drawbacks of cellular shades for arched windows are: most are stationary rather than operable, custom-fit options are pricier than standard rectangular blinds, the honeycomb cells collect dust and need periodic cleaning, and paper-style budget shades can sag in high humidity rooms like bathrooms.
Can you put blinds on an arched window?
Yes, you can put blinds on an arched window, but standard rectangular blinds will leave gaps along the curve. A custom-cut cellular shade, a stationary arch blind, or a template-made shade for an eyebrow arch will follow the radius cleanly and block light or filter it properly.
What company makes the best cellular shades?
Bali, Blinds.com, Graywind, Hunter Douglas, and SelectBlinds lead the custom cellular arch shade market for made-to-measure orders. For DIY no-tools options, Redi Shade, MYshade, Changshade, HOMEDEMO, and Maritown offer affordable arch shades that trim to fit at home.
How do you measure arched windows for shades?
Measure the width at the base of the arch and the height from the base to the highest point of the curve. For perfect half-circles, the width and height are equal. For eyebrow arches or non-perfect curves, trace the shape onto craft paper to create a template and use that template to size your custom order.
Final Verdict
The Redi Shade Original Arch remains the easiest recommendation for most people hunting for the best cellular shades for arched windows. It is cheap, removable, and battle-tested across thousands of installs. If you want a real honeycomb blackout upgrade, the MYshade is the strongest value pick in this roundup, and the HOMEDEMO is the premium choice when easy-peel cleaning matters. Match the shade to your arch shape, light needs, and budget, and you will avoid the gaps and glare that come with forcing rectangular blinds onto a curve.
