How to measure a window for Blinds
Measuring – OUTSIDE the Recess
Decide by how much the fabric should overlap the recess (we suggest at least 50mm (2") on each side) and measure the total width. Measure the drop in the same way.

Measuring – INSIDE the Recess
We require the exact recess width and drop. We will make the necessary allowances.
Remember to take the recess measurement at the top of the window where the blind is to be fitted. For roller blinds the fabric width will be 38mm (1.5") narrower than the recess width.
