The blind sits inside the frame. For a flush fit you need at least 70 mm of depth (90 mm for a double). The width is bracket to bracket, so it includes the controls and brackets. Measure in millimetres with a metal tape.

Check the recess depth
Measure from the glass to the front edge of the frame. Under 70 mm (90 mm for a double), or tiles, handles or sensors in the recess? Choose a face fit.

Measure the width three times
Inside the frame, at the top, middle and bottom. Write down all three.
TipUse a metal tape. Fabric tapes stretch.

Inside the frame, on the left, centre and right.

Send the smallest numbers, exactly
Narrowest width and shortest drop, in millimetres. Pick the chain side too. Readings 10 mm or more apart mean the frame isn’t square: send us a photo before you order.
Watch outDon’t take anything off. We make the deduction at the factory.
Questions
- What is the minimum recess depth?
- For a flush recess fit, at least 70 mm for a single roller blind and 90 mm for a double. Shallower than that, choose a face fit.
- Do I take anything off my measurements?
- No. Send the narrowest width and shortest drop exactly as measured for a recess fit, or the finished size for a face fit. The factory makes any deductions.
- My window isn’t square. Which number do I use?
- The narrowest width and the shortest drop. If your readings are 10 mm or more apart, send us a photo before you order so we can suggest the best fit.
- Is a double roller measured differently?
- No, measure it like a single blind. A flush recess fit needs at least 90 mm of depth.
