Blinds for Large Windows Designed for Scale, Made to Last

We offer extra wide blinds in 5cm increments to suit oversized French doors, open-plan spaces and tall period sash windows. Each blind is stitched by hand, blackout lined, and weighted for even folds across the full span.

You can fit inside the recess, mount above the frame or stretch wall to wall. Our team will help you find the best approach for your space when it comes to extra wide blinds.

FAQs

What is the best blind for a large window?

Blackout-lined Roman blinds are the best blinds for large windows, especially when interlined and stitched to hang cleanly across a wide span. They insulate, fold neatly and bring softness to glazed spaces. The interlining provides structure that prevents sagging whilst the blackout lining ensures complete light control when you need it. For those who prefer softer light filtering during the day we can discuss alternative lining options that still maintain the blind's shape and drape beautifully across wider expanses.

What’s the maximum size you offer?

Our blinds go up to 200cm wide and 175cm drop. Need a larger solution? Our bespoke service is on hand to help, and can assist with blinds up to 400cm wide.

Can one blind cover a run of bifold doors?

Yes, many customers choose one extra wide blind for full bifold runs. We’ll guide you on the best fitting point based on usage and handles.

How do I keep large blinds from sagging?

Our interlining adds structure. Every fold is hand-stitched to hold shape across the span. No sagging, warping or fabric droop over time.

Can I hang blinds above a radiator or on an angled wall?

Yes, in fact, mounting your blind just above the window frame (and radiator) is often the best way to let warmth circulate without obstruction. For angled or sloped walls, especially in loft conversions, we can guide you on how to measure and mount to keep the blind neat, even and practical. Just send us a quick photo and we’ll walk you through it.

Will extra wide blinds block too much natural light when lowered?

Not necessarily. Whilst our standard blackout lining provides complete darkness, you can choose light-filtering linings that gently diffuse sunlight whilst maintaining privacy. When raised, wide window blinds stack neatly at the top, leaving your view completely unobstructed. 

The beauty of made-to-measure is that you control exactly how much window remains uncovered, maximising natural light when you want it.
