How to Measure an Inside Recess Roman Blind?
First measure the width and then the drop of your window.
To measure the width of the window recess, take three measurements at different points from wall to wall, inside the window recess and write down the smallest measurement.
To measure the drop, take three measurements at different points of your window recess, from top to sill and write down the smallest measurement.
Both these measurements taken together are called the 'Inside Recess' (See fig. 1).
