Triangular Window Blind Ideas

We love interesting windows at The Scottish Shutter Company. And nothing screams ‘quirk’ quite like triangular windows!

A striking architectural feature, triangular windows can look stunning… But how on earth do you dress them? Standard window treatments often fall short of the triangular window’s very specific geometric requirements, and that’s just not good enough.

In this blog, we present you with three creative and functional triangular window blind ideas tailored to these unique window shapes. 

Why Are Triangular Windows Difficult To Treat?

Adding a unique vibe to any room, triangular windows are aesthetically interesting, immediately drawing the eye. Quite the talking point, too!

Unfortunately, these alluring design features can make standard window coverings unfit for the job. Most blinds, shutters, and curtains are designed to fit rectangular and square windows; after all, off-the-shelf, budget solutions are unlikely to fit triangular windows, creating issues with excessive light, glare, heat, and a complete lack of privacy. 

For some rooms and some people, an undressed window is perfectly acceptable. Streaming sunlight can feel like some kind of magic, can’t it? But for bedrooms and living areas, where shade and privacy are a must, what window covering solutions are there?

Let’s run through triangular window blind ideas to get your inspiration flowing.

Cellular Shades

Let’s jump in with cellular shades. First on our list of triangular window blind ideas, cellular shades are a type of fabric blind constructed from a honeycomb pattern of fabric cells. The air pockets that sit within the cells work efficiently to trap heat, offering great insulation in the cooler months and keeping the heat out in the summer. 

Benefits

That’s right, cellular shades are great insulators. You can choose from sheer shades that diffuse the light beautifully or more opaque fabrics that block the light more efficiently. 

If you live in a busy bustling road, cellular shades help to absorb excessive noise. And the best bit? Cellular shades are completely customisable to fit triangular dimensions! 

Considerations

Due to their complex structure, you should use a professional for measurement and installation. There’s no point investing in fabulous cellular shades only to have them mismeasured, leaving you with large gaps around the shades and a wonky appearance.

Choosing the right fabric and colour for your room decor can be tough, especially when you want a functional shade. 

Cellular shades are one option, but what other triangular window blind ideas exist?

Vertical Blinds

Next on our list of triangular window blind ideas is the vertical blind.

Blinds are many homeowners’ go-to window shading solutions, and for good reason. Vertical blinds are practical and more affordable than shutters. They consist of several individual slats or vanes that hang vertically and can be adjusted using a wand or chain. 

Benefits

Vertical blinds can quickly cover large windows. They are extremely versatile and adaptable to different window shapes, making them a great choice for quirky, awkward windows like circles, arches, and, you guessed it, triangles! 

Because the slats or vanes of vertical blinds can be adjusted, they give the user precise control over light and privacy. Available in various materials like vinyl, fabric, and aluminium, there are vertical blind designs for every room, even humid environments like bathrooms and kitchens. 

Considerations

Though versatile, vertical blinds don’t typically offer the same level of insulation as other window treatments. Unlike cellular shades, which fit snugly into the shape of the window to form a millimetre-perfect barrier, the hanging vanes of vertical blinds can be drawn across and adjusted instead. 

Though the array of vertical blinds is broad, they aren’t the most flexible regarding aesthetics, and they require a little more care and attention to keep them in good condition.

Internal Wooden Shutters

These aren’t blinds per se, but shutters are worth including because they offer such a compelling solution. Wooden shutters are an incredible way to add impressive triangular window coverings. They tend to be made of panels with adjustable louvres, giving you control over light and privacy. Solid shutters are an alternative; these are composed of a single panel of wood, meaning they are either open or shut with no range of light control.

Benefits

Shutters are timeless. They add a sophisticated vibe to any room, fit in with any interior design plans and are sturdy and durable. 

Beyond their timeless, elegant aesthetic, shutters offer incredible light and privacy control. Users can fully open the hinged shutter panels and open their windows to breathe in the fresh air and watch the sun go down, or keep shutters closed but adjust the louvres for optimum light, privacy and airflow levels. 

Internal wooden shutters can be custom-made to your measurements. Even awkward triangular ones. And that means that wooden shutters could be the window shading solution of your dreams. 

Considerations

Wooden shutters are a premium product and a lasting investment. Due to the expertise involved in the manufacturing process, bespoke shutters will be more expensive.

Use appropriate materials in humid spaces, like bathrooms and kitchens. Thankfully, shutters can withstand humidity easily!

Celebrate Your Awkward Windows!

Triangular windows add an interest that can’t be beaten, but they come with aesthetic and functional challenges, making triangular window blind ideas tricky.

However, with shading solutions like cellular shades, internal wooden shutters, and vertical blinds, homeowners can achieve effective light and privacy control that enhances both style and function. 

Which option spoke to you most? Each solution offers unique benefits, allowing for tailored window covering solutions that meet your specific needs.

Frequently Asked Questions

Can you get blinds for triangular windows?

Yes. Cellular shades, vertical blinds, and custom shutters can all be manufactured to fit triangular windows. Each option is made to measure, ensuring a precise fit that standard rectangular blinds cannot provide. A professional survey is recommended to capture the exact angles and dimensions.

What is the best blind for a triangular window?

Cellular shades are the most popular choice because they fit the triangular shape precisely with minimal light gaps and offer excellent insulation. Wooden shutters are a premium alternative that adds lasting value and full light control. The best option depends on your priorities for light control, insulation, and budget.

How much do triangular window blinds cost?

Pricing depends on the size of the window, the product chosen, and the fabric or material specification. Cellular shades for a standard gable window typically start from a few hundred pounds, while bespoke shutters sit at the higher end. Contact a specialist for an accurate quotation based on your exact measurements.

Do triangular blinds block out light?

Cellular shades in room darkening fabrics can reduce light to very low levels, though a true blackout is difficult on any shaped window due to the geometry involved. Solid panel shutters offer the most complete light block when fully closed. For bedrooms, a combination of room darkening cellular fabric and careful fitting minimises light gaps to just a few millimetres.

Can you put shutters on a triangular window?

Absolutely. Full height shutters with adjustable louvres can be custom made to fit triangular windows, giving you precise control over light, privacy, and airflow. They are a premium, long lasting solution that suits both modern and traditional interiors.

How do you measure a triangular window for blinds?

Triangular windows require accurate measurements of the base width and both angled sides, plus the vertical height from the base to the apex. Even small errors can result in gaps or a poor fit, so professional measurement is strongly recommended. A specialist will also assess the recess depth and any obstructions that affect the installation method.
