Best Blinds for Bay Windows (2026 Guide)
Choosing the best blinds for bay windows can be tricky. Bay windows are one of the most attractive features in a UK home – but also one of the trickiest to dress well. Because a bay is made up of two, three or five angled panes rather than one flat window, a single blind almost never fits the whole thing. Each panel typically needs its own made-to-measure blind.
The short answer: for square (90°) box bays, wooden or aluminium Venetian blinds give the cleanest, most architectural look. For splay bays (the 45° angled bays most common in UK homes), slim-profile roller, vertical or 25mm Venetian blinds fit the tight corners best. For curved bow windows, segmented Roman blinds follow the arc without leaving gaps.
Below we break down each bay shape in detail, with a comparison table, measuring tips and answers to the questions we hear most often on site visits across West Yorkshire. See our full range of made-to-measure blinds for more styles.
BestBlinds for Bay Windows, Shape by Shape
| Bay Window Shape | Best Blind Types | Why It Works | Rooms It Suits Best |
|---|---|---|---|
| Square / Box Bay (90°) | Wooden or Aluminium Venetian | Rigid slats mirror the frame’s straight lines; add ladder tapes for an architectural finish | Living rooms, studies, period homes |
| Splay Bay (45°) – most common UK shape | Roller, Vertical or 25mm Aluminium Venetian | Slim headrails minimise light gaps in the corners between mullions | Living rooms, bedrooms, terraced houses |
| Bow / Curved Bay | Segmented Roman blinds | Follows the window’s arc rather than fighting it with a flat blind | Victorian and Edwardian homes |
| Any bay needing full blackout | Roman or roller blinds with blackout lining, fitted inside the recess | Blocks light seepage at panel edges better than surface-mounted blinds | Bedrooms, home cinemas |
Square Bays: Venetian & Wooden Blinds
Wooden and aluminium Venetian blinds are the top choice for square, 90° box bays. Their rigid slats and clean lines echo the straight architecture of the frame, and tilting slats give you precise control over light and privacy – ideal for south-facing bays that get strong sun through the day.
Add matching ladder tapes across each panel for a coordinated, tailored finish that ties the whole bay together.
Curved Bows: Segmented Roman Blinds
Curved bow windows do not have straight sections, so rigid blinds rarely sit well. Segmented Roman blinds are cut to follow the arc of the window, gathering into neat folds when raised and creating a soft, layered look when lowered.
They also work well paired with a thermal interlining, helping to reduce heat loss through the large glazed area a bow window usually has.
How ToMeasure a Bay Window Correctly
- Measure each panel of the bay separately – width and drop, in millimetres.
- Take three width measurements per panel (top, middle, bottom) and use the smallest.
- Note the angle between panels – splay bays are usually 45°, box bays 90°.
- Decide inside-recess or face-fit – recess-fit blinds need enough depth to clear the window handle.
- Or skip all of this: book a free measuring visit and one of our fitters will measure, advise and quote on the spot.
Avoid TheseCommon Bay Window Mistakes
- Buying one wide blind to span the whole bay instead of fitting each panel individually.
- Ignoring window handle clearance when choosing a recess-fit headrail.
- Choosing a bulky headrail for a splay bay, which leaves visible light gaps at the corners.
- Not accounting for radiators or sills that sit directly under the window.

I have dealt with Mo for many years and never had any issues with his knowledge or service, nothing is ever too much bother he goes out of his way to accommodate his clients requests. The product he sells is excellent quality at affordable prices I highly recommend Mo and Hermis Blinds.
Brilliant service from start to finish I can’t recommend highly enough. We started with one blind and the service was so good we ended up replacing all blinds. Really knowledgeable and friendly team with value for money products
I cannot recommend Mo highly enough. His service and professionalism is unrivalled and he goes above and beyond to make sure you are happy with the blinds. We ordered 4 blackout blinds and 2 Velux blinds, the quality is great as was the price. I wouldn’t even bother getting anybody else out, Mo is the only person you should choose for your blinds!
Hermis Blinds did a fantastic job installing our roman blinds – beautiful finish, great service, and highly recommend!
The blinds were installed with no mess . I am very happy with the service.
Friendly and professional, was very swift in giving a quote and brought examples of blind materials. Post installation we noticed a small mark/hole in the blind, which they happily replaced the next day. Would recommend, honest business and fairly priced.
Great fitment, lovely man and the cheapest quote out of all 8 companies. 10/10 recommend!
Great service. fantastic blinds, such a good quality. I truly recommend this. Most trusted! I will probably get the blinds again from you guys soon! 🙏🙏
