Measuring Guides

Roller Blinds

Measuring for your new blinds is easier than you might think! All you have to do is follow our simple tips, double-check everything you do, and set aside some time to do it. Happy measuring!

This guide works for:
  • Standard Roller blinds
  • Motorised Roller Blinds

Standard Windows

Recess fitting (Inside Mounting)

Measure the full width and height of the recess [INSIDE the hole in the wall] and we will make the appropriate deductions to ensure a perfect fit.

  • Measure in 3 places for both the width and the drop, use the smallest measurement.
  • Don’t make any deductions, we’ll deduct from the width to ensure your blind fits perfectly (0.5cm for standard rollers).
  • Use a metal tape measure, cloth ones can stretch and give you inaccurate measurements
Top-Tip:

Check that your recess is deep enough to fit the blind into, also bearing in mind any obstructions such as handles.

Top-Fix Wall-Fix
50mm 70mm

Exact fitting (Outside Mounting)

Measure the full width and height of the window and add a little extra to the top and to each side, we will make the blind to the size you specify with no deductions.

  • To minimize light leakage we recommend that the blind overlaps the window recess by at least 10cm at the top and 5cm each side.
  • For Blackout blinds we suggest at least 10cm on each side to ensure no light leakage.
  • The overlap at the bottom of the blind is a matter of personal choice but please take into account obstacles such as furniture.

Other Windows

Part-tiled recesses

If you have tiles part-way up your recess (often the case in kitchens and bathrooms) then the space between them is most likely to be the narrowest point in the recess.

Measure at the top of the recess and between the tiles. Compare the two measurements; and use the smaller measurement.
