Measuring for Blinds

Top Tip: Always use a metal tape measure for accuracy

Blinds may be fitted either inside or outside the window recess. 

The blind should be fitted outside the recess if the recess is less than 7.5 cm (3") deep; the window opens inwards; or if the window is not straight (ie if the width or drop varies by more than 2 cm).

Measuring for a Recess Fitted Blind:


Remember to choose 'recess size' on the order form.

Measure the width and the drop inside the recess, in at least three positions, taking account of any protrusions such as tiles and dado rails.

Be sure to measure into the corners as this measurement is quite often smaller than the rest of the window opening.

Use the smallest width and drop measurement to ensure the blind will fit.

If you give us a recess size we willl make the necessary reduction for you to ensure the best fit and smooth operating of the blind.

Measuring for a blind to be fitted outside of the recess:


If a blind is being fitted outside the recess, please choose 'blind size' on the order form and the blind will then be manufactured to the size quoted.

Each window is different and should be treated individually, but as a rough guide, allow 10 cm either side and below the window.

If you supply 'blind size' measurements, the blind will be made to the size specified with no reductions. 

Please note that blind size is the whole space the blind takes up including the chain

Several Blinds in the same window?

If more than one blind is being fitted in a window please quote the size of each individual blind rather than the overall recess size.
