Measuring Guide

Measuring for standard windows

Recess Fitting

This is the measurement you need to take if you want your blind to fit inside the window recess. Measure the full width and height of the recess [the size of the hole if you like] 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 measurements
  • don't make any deductions, we will do that for you to ensure your blind fits perfectly
  • use a metal tape measure, cloth ones can stretch and give you inaccurate measurements

Exact Fitting

This is the measurement you need to take if you want the blind to hang outside the recess overlapping the window. In this case we will make the blind to your specified size with no deductions.


  • measure the exact width of the area you would like the blind to overlap. To minimize light leakage we recommend that the blind overlaps the window recess by at least 70mm at the top and 50mm each side
  • the overlap at the bottom of the blind is a matter of personal choice but please take into account obstacles such as radiators
  • if you are replacing an existing blind with one of the same size simply measure the blind and specify exact fitting, we will make you one the same size
  • Top Tip: Measuring for your roller blind is slightly different because the overall width of the blind including the brackets is approx. 3.5cm wider than the fabric. With this in mind you can choose to measure from where the brackets will sit (‘bracket to bracket’) or the area the fabric will cover (‘fabric width’).

Measuring for loft windows

VELUX ® & Fakro loft windows

Every VELUX ® and Fakro roof window carries a data plate that details the code of the window. Check you window's code number and simply select that when ordering you blind.


  • put your tape measure away, you don't need it!
  • order the correct code and your blind will fit perfectly
  • if your data plate is missing measure the visible glass size and give us a call, we may be able to identify your window code

Keylite loft windows

Keylite make it a little more difficult for you to save money on replacement loft blinds by not putting an identification code on the windows.

To identiiy the correct size blind for your keylite window you just need the size of the window unit. If the window is an old unit and you no longer have access to the size ordered simply measure the visible glass (width and drop), give us a call and we can tell you which blind to buy.
