For Outside Measurement
The recess width and drop should be measured in several places, giving the smallest dimensions in both cases.
Allow for obstructions such as tiles, catches, handles or skirting boards. When ordering, state measurements as RECESS SIZE and we shall make the necessary allowances.
For Inside Measurement
Decide how much you want the blind to overlap the recess. We recommend a minimum overlap of 50mm (2″) each side.
When ordering, state the measurements as BLIND SIZE, no deductions will be made.
PLEASE USE A METAL TAPE MEASURE TO ENSURE ACCURATE MEASUREMENTS.
