First you need to decide where your blind is going to be fitted, either inside or outside the window recess.
Inside your window recess
Measure the width and drop in at least two places and use the smallest measurement.
Outside your window recess
Measure the width and drop according to where you want the blind to sit. The norm is approximately 3″ above the window and 1″ below the sill, and about 2″ over each side.
You can provide all measurements in either inches or centimetres, whichever you prefer
Now decide what Fabric & Quantity you require.
