The Ultimate Guide to Blinds for Round Windows

Round windows are beautiful architectural features, but they can be a real head-scratcher when it comes to finding blinds. The truth is, off-the-shelf options just won't cut it. The only real solution is a custom, made-to-measure blind crafted specifically for a circular frame. This is the secret to getting that perfect fit, controlling the light, and keeping the window's unique charm intact.

Why Standard Blinds Won't Work for Your Round Windows

A round window is more than just a source of light; it’s a design statement. Its gorgeous curved shape is exactly what makes it special, but it’s also what makes standard rectangular blinds completely unsuitable. It’s the classic square peg in a round hole problem – a recipe for frustration and a look that just feels… off.

Standard blinds are built for straight lines and sharp corners. When you try to force one onto a circular frame, you’re left with awkward, gaping holes at the top, bottom, and sides. These gaps don’t just look clumsy; they completely undermine the whole point of having blinds in the first place.

It’s not just about how it looks; it’s about how it works. The gaps from ill-fitting standard blinds let light stream in when you don’t want it, compromise your privacy, and even hurt your home's energy efficiency. They fail at the very job they're meant to do.

This infographic really shows the difference between trying to make a standard blind work and choosing a custom-fit solution.

As you can see, a custom blind is the only way to get that flawless finish with total control over light and privacy.

The Rise of Custom Solutions

These days, homeowners are moving away from one-size-fits-all decor. The UK's window covering market, valued at roughly USD 1,447 million in 2024, is set to grow as more people seek out bespoke solutions for unique features like round windows. You can dive deeper into these industry insights on the window covering market. This trend shows that opting for custom blinds isn't just a practical necessity; it's a smart and popular design choice.

Exploring Your Options for Circular Window Blinds

Finding the right covering for a circular window is more than just blocking out light; it’s about enhancing a beautiful and unique architectural feature. Standard rectangular blinds just won't do. The options for round windows are specialised, each designed to work with the circular shape to deliver on light control, privacy, and, of course, style.

Let's go beyond a simple list. To really figure out what’s best for your space, you need to understand how these different blinds actually work on a round frame. Each solution strikes a different balance between function and aesthetics, so getting to grips with the mechanics is the first step to making a smart choice.

Cellular Blinds: The Fanning Favourite

Cellular blinds, which you might know as honeycomb blinds, are hands down one of the most practical and popular choices for round windows. Their unique construction is what makes them such a perfect fit.

Think of how a handheld fan opens; the material spreads out gracefully from a single point to fill the arc. Cellular blinds operate on the very same principle. They are usually fixed at a central hub and fan outwards to cover the window, collapsing back just as neatly when you want an unobstructed view.

This fanning mechanism is brilliant because it leaves no awkward gaps. The blind fits snugly inside the frame, giving you fantastic light control and privacy. As a bonus, its honeycomb cell structure provides excellent thermal insulation.

While many cellular blinds for round windows are stationary (either open or closed), some models are fully operable, giving you the flexibility to adjust the light as you see fit.

Plantation Shutters: The Architectural Classic

If you're after a more structured and permanent window treatment, plantation shutters are an incredibly elegant option. They aren't blinds in the traditional sense; they're a robust, timeless covering that can be custom-made to fit any shape, including perfect circles.

With plantation shutters, a custom circular frame is built to the exact dimensions of your window. Horizontal louvres are then fitted inside this frame, which you can tilt to get just the right amount of light and privacy.

The key benefits of plantation shutters include:

• Durability: Made from solid wood or hard-wearing composite materials, they're built to last for years.

• Light Control: The adjustable louvres offer unbeatable control over the amount and direction of incoming sunlight.

• Aesthetic Appeal: They bring a classic, architectural elegance to a room that can even increase your home's value.

Because they are a permanent fixture, shutters become an integral part of the window itself, creating a polished and sophisticated look that’s hard to replicate.

Fabric Blinds: The Sunburst Effect

For those looking for a softer, more decorative touch, custom fabric blinds like pleated or Roman styles are a fantastic choice. When designed for a circular window, these blinds create a stunning "sunburst" effect.

The fabric radiates outwards from a central point, forming beautiful, soft pleats that turn the window into a true focal point. While many of these are stationary and primarily for decoration, they are brilliant at diffusing harsh sunlight, filling the room with a warm, inviting glow. You can explore the full range of possibilities with custom blinds that are made to measure for your unique space.

Comparing Blinds for Round Windows

With several great options available, choosing the right one comes down to your priorities. This table breaks down the key features of each style to help you decide what's best for your home.

Blind Type	Best For Light Control	Privacy Level	Aesthetic Style	Operation Method
Cellular Blinds	Very Good - blocks light effectively with no gaps.	Excellent	Modern & Minimalist	Often stationary, some operable (fan-like)
Plantation Shutters	Excellent - adjustable louvres offer precise control.	Excellent	Classic & Architectural	Tilting Louvres
Fabric Blinds	Fair - diffuses light rather than blocking it.	Good	Decorative & Soft	Mostly stationary (fixed sunburst)

Ultimately, whether you lean towards the modern efficiency of cellular blinds, the timeless elegance of shutters, or the decorative charm of a fabric sunburst, there's a perfect solution to dress your circular windows.

Choosing the Right Materials and Colours

Picking the perfect material and colour for a round window blind is a bit like choosing a frame for a beautiful painting. It’s the finishing touch that can define the window's character, shape the room's atmosphere, and control the light and privacy you get. This isn't just about looks; it's about making a practical choice that suits the room's purpose.

For example, a light, airy linen fabric could be just the ticket for a living room, gently diffusing harsh sunlight into a soft, welcoming glow. For a bedroom, however, you'd likely want a blackout material to block out streetlights and guarantee a good night's sleep.

Matching Materials to Your Needs

The best place to start is by thinking about how you use the room. Each space has its own demands, so you need a material that's up to the job.

• For Thermal Insulation: Cellular or honeycomb blinds are fantastic insulators. Their clever cell-like structure traps air, creating a barrier that helps keep your home warmer in the winter and cooler in the summer. You might even see a difference in your energy bills.

• For Moisture-Prone Areas: Round windows in bathrooms, kitchens, or utility rooms need materials that won’t mind a bit of humidity. Faux-wood or composite shutters are ideal here, as they're built to resist warping, cracking, and mould.

• For a Classic, Robust Look: You really can't beat the timeless appeal of solid wood. Our guide to [stylish wooden shutters](https://www.blindsmart-im.co.uk/wooden-shutters) shows how this durable, elegant option can add serious architectural character to any room.

Choosing the right material isn’t just about aesthetics; it’s a practical investment in your home’s comfort. A thermal blind in a draughty hallway or a moisture-resistant shutter in a steamy bathroom makes a real difference, day in and day out.

This focus on tailored solutions is something we see a lot in the UK window furnishings market, where high-quality, custom-made products are in high demand. There’s also a growing appetite for sustainable options like FSC-certified wood and recycled fabrics, especially for bespoke projects.

Harmonising Colours with Your Decor

Once you've landed on the right material, it's time for the fun part: choosing a colour. This decision can completely change the feel of your space and how much the window stands out.

Do you want your round window to be a showstopper or blend in quietly? To create a bold focal point, go for a colour that contrasts sharply with your walls—imagine a deep navy blind against a soft grey wall. This approach really draws the eye and makes a feature of the window's unique shape.

On the other hand, if you're aiming for a more seamless, calming effect, choose a colour that’s a close match to your wall paint or trim. This creates a cohesive look that can make the room feel larger and more peaceful, letting the window's architectural beauty speak for itself. Neither way is right or wrong; it all comes down to your personal style and the story you want your room to tell.

How to Measure Your Round Window Accurately

Getting the measurements spot-on for a round window blind is probably the most critical part of the entire job. With a standard square window, you might have a tiny bit of wiggle room, but with a circle, precision is everything. Think of it like getting a bespoke suit made – if the tailor is even a centimetre off, the whole thing just won't sit right.

Before you do anything else, find a good quality steel tape measure. The flimsy fabric or plastic ones you might have in a sewing kit can stretch over time, which is the last thing you want when accuracy is key. The goal here is to figure out if your window is a truly perfect circle, because even the slightest imperfection can throw off the fit of a made-to-measure blind.

Nailing the Diameter Measurement

The secret to a perfect fit isn't measuring once, but measuring at least three different ways. This little bit of extra effort is a brilliant way to catch any subtle warping or imperfections in the frame that you just can't see by eye.

Here’s the simple process I always follow:

1. Horizontal Check: Start by measuring the width of the window from the inside edge of the frame. Go straight across the widest point, like you’re drawing a line from 9 o'clock to 3 o'clock.

2. Vertical Check: Next, do the same for the height. Measure from the very top of the inside frame straight down to the very bottom – from 12 o'clock to 6 o'clock.

3. Diagonal Checks: Finally, take at least two diagonal measurements. A good way to do this is to measure from 2 o’clock to 8 o’clock, and then again from 10 o’clock to 4 o’clock.

If all your numbers match up perfectly, great! You’ve got a true circle. But don't worry if there are small differences between them; it's quite common. The golden rule is to always use the smallest measurement you recorded. This guarantees your new blind will fit smoothly inside the frame, even at its narrowest point.

It's always a good idea to measure twice and order once. Double-check your numbers before you finalise anything. While some suppliers offer a ‘sure-fit guarantee’, getting it right from the outset saves a lot of hassle and potential delays.

Inside Mount vs. Outside Mount: What's the Difference?

The last decision you’ll need to make is how the blind will be mounted. This really comes down to the depth of your window frame and the overall look you're hoping to achieve.

• Inside Mount: This is the go-to choice for most round windows. The blind fits snugly inside the window recess, giving you a clean, built-in finish that really shows off the unique shape of the window. This works perfectly if your frame is deep enough to hold the mounting brackets.

• Outside Mount: If your window frame is quite shallow or if you'd like to create the illusion of a larger window, an outside mount is the better option. Here, the blind is fitted onto the wall or trim surrounding the window. For this style, you’ll need to measure the total area you want the blind to cover, making sure to add a few centimetres to the width and height for good light coverage.

Installing and Automating Your New Blinds

So, your perfectly measured custom blinds have arrived. Fantastic! Now for the final step that brings it all together: the installation. This is where your vision becomes a reality, and while fitting blinds to a circular frame might sound a bit daunting, it’s often more straightforward than you’d think. You've really got two paths here: a DIY approach or calling in a professional.

If you’re a confident DIYer, the process usually involves mounting the central hub or the surrounding frame securely. You’ll need the standard toolkit – a drill, a spirit level, and the right fixings for your wall. But for a guaranteed perfect finish, especially with something substantial like plantation shutters, getting a professional in ensures every component is flawlessly aligned and secure. It's also worth remembering that some window types have simpler, no-drill options, which you can read about in our guide to [Perfect Fit and Intu blinds](https://www.blindsmart-im.co.uk/perfect-fit-nodrillblinds-intu).

Embracing Modern Automation

Beyond the initial fitting, the real game-changer for round window blinds is automation. Let's be honest, manually operating a blind on a high, hard-to-reach, or awkwardly placed circular window is a pain. This is exactly where modern tech provides an elegant and genuinely useful solution.

Motorisation turns your blinds from a static feature into a dynamic part of your home. With a simple press of a button, you can open, close, or tweak them effortlessly. This isn't just a gimmick; it’s a practical upgrade that makes daily life that little bit easier and more comfortable. You get to control light and privacy without any fuss.

Imagine waking up and letting the morning light flood in with a single command from your bedside. Or closing the blinds in a high stairwell window without teetering on a ladder. That's the real-world benefit of automating your blinds for a round window.

This shift towards smart technology is a massive trend. In fact, smart and motorised blinds are the fastest-growing part of the UK window coverings market. For unique shapes like round windows, where manual operation is a real challenge, this kind of tech is invaluable.

Integrating with Your Smart Home

The ultimate step in convenience? Connecting your motorised blinds to your smart home system. Most modern motors are designed to play nicely with the big platforms, giving you seamless control.

• Voice Commands: Link your blinds to Amazon Alexa, Google Home, or Apple HomeKit and you can operate them with simple voice instructions. "Alexa, open the landing blind." Done.

• Automated Schedules: You can program your blinds to open and close at set times, mimicking a natural sunrise or boosting your home security when you're away.

• App Control: Use a smartphone app to manage your blinds from absolutely anywhere, whether you're in the next room or on holiday.

By automating your new blinds for a round window, you're not just adding a window covering. You’re investing in a smarter, more responsive living space that brings both next-level convenience and a touch of modern sophistication to your home.

Still Have Questions About Round Window Blinds?

It's completely normal to have a few questions still buzzing around, even after looking at all the options. Round windows are a bit special, and they come with their own unique quirks. Getting everything clear before you commit is always the smart move.

Let's walk through some of the most common questions we hear from homeowners. Getting these answers sorted will help you feel confident that you’re choosing a blind you’ll love for years to come.

Can You Put Blinds on a Window That Doesn't Open?

Yes, absolutely. In fact, that’s what they’re designed for. Most round windows are fixed in place – think of those classic porthole or feature windows. They don't open, and that's perfectly fine.

All the styles we’ve looked at, from cellular blinds and pleated fabrics to elegant plantation shutters, are made to fit snugly into these non-opening frames. The installation is all about creating a secure, seamless look that complements the window’s shape, without ever needing to worry about the mechanics of an opening sash.

How Do You Clean Blinds on a Round Window?

Keeping your new blinds looking fresh is probably easier than you imagine. The best way to clean them just comes down to the material.

• For Fabric Styles (Cellular & Pleated): A gentle once-over with a feather duster or the soft brush attachment on your hoover will do the job. If you notice a small mark, just dab it carefully with a damp cloth and a tiny bit of mild soap.

• For Plantation Shutters (Wood & Faux Wood): These are even simpler. A quick wipe with a dry microfibre cloth is usually all it takes to get them looking spotless again.

A little bit of regular, gentle cleaning is all it takes to keep your blinds looking their best. Think of it as light maintenance that protects the materials and mechanism for the long haul.

Are Round Window Blinds Expensive?

Because they are always made-to-measure, blinds for a round window are definitely more of an investment than a standard, off-the-shelf blind. There’s no one-size-fits-all price, as the final cost really depends on a few things:

• The size of your window.

• The material you choose (for example, premium hardwood shutters will cost more than a standard cellular fabric).

• The operating system, especially if you go for something like motorisation.

While the upfront cost is higher, it’s helpful to think of it as a long-term addition to your home. A perfectly fitted, high-quality blind does more than just look good; it can genuinely improve your home's energy efficiency, give you much-needed privacy, and become a real standout design feature.
