This is the measurement that you need to take if you want your blinds to fit inside the window recess. Measure the full width and height of the recess area – the size of the hole if you like – (see diagram A) and we will make the appropriate deductions for you to ensure a perfect fit.
Measure in 3 places:
for both the width and the drop, use the smallest measurements
Don't make any deductions:
we will do that for you to ensure your blind fits perfectly with our system
Use a metal tape measure:
cloth ones can stretch and give you inaccurate measurements
