How to Measure for Blinds

Accurate measurements are the key to blinds that fit well. You will need a steel tape measure, a pencil and paper. Always measure in millimetres, and measure each window separately, even if they look the same.

Step 1: Choose inside or outside fit

Inside fit (recess): the blind sits inside the window frame for a neat, built-in look. You need at least a few centimetres of flat depth in the recess.
Outside fit (face): the blind is mounted on the wall or architrave and overlaps the window, which helps block light around the edges.

Step 2: Measure the width

Inside fit: measure the width inside the recess at the top, middle and bottom. Write down the smallest measurement. Don't make deductions; these are allowed for when the blind is made.
Outside fit: measure the width of the area you want to cover, adding overlap on each side for better light control.

Step 3: Measure the drop (height)

Inside fit: measure from the top of the recess to the sill on the left, centre and right. Write down the longest measurement.
Outside fit: measure from where the bracket will be mounted to where you want the blind to finish.

Step 4: Check for obstructions

Note anything that could get in the way: window handles, winders, alarm sensors or tiles.
