What's the best blind for an awkward bay window?

Bay windows expose the weakness of one-size-fits-all blinds: the corner where two panels meet can admit a surprising strip of light or prevent the blind moving freely.

The two products worth comparing first

Your priority	Specific product	Why it deserves a place	Reason to hesitate
First shortlist	Blinds 2go PerfectFIT Venetian Blinds	A specific made-to-measure range for suitable beaded uPVC frames, useful when the window opens in several sections and drilling is undesirable.	Only compatible with certain frame and beading profiles; it is not a universal bay-window solution.
Alternative	Hillarys made-to-measure Roman blinds	A fitted option to explore when softer fabric and a coordinated appearance are priorities across a bay.	The fitting, stacking space and overlap at angled joins need a survey; there is no one standard SKU.

The buying decision that matters

Measure each pane separately and note handle positions, bay angles and how far each sash opens. Request fabric samples before choosing blackout claims; edge gaps can limit room darkening.

Measure the real room

Measure each pane in several places: bay frames can be out of square. If you’re fitting inside the recess, account for handles, vents and the clearance needed for the blind’s operating mechanism.

Small details with big consequences

Blackout fabric alone does not guarantee a blackout result. Gaps between adjacent blinds and around roller hardware often matter more. Overlapping curtains or a suitable cassette system may be better where daytime darkness is important.

Our recommendation

Choose PerfectFIT only for a compatible frame. For timber or awkward angles, a surveyed made-to-measure option from Hillarys may be more appropriate than guessing a generic width.
