How to measure? For angled bay windows
You will need:


Cardboard & scissors

A tape measure

A pencil & paper


Step 1
Create cardboard cut-outs to use as measuring guides. The cut - out will be 30cm long by the depth of blind you have chosen plus any obstructions. For example when allowing 2cm for handles and choosing a standard Roman with 2.5cm headrail the measurement you’d create a cut - out that is 4.5cm by 30cm (2+2.5=4.5cm).
Step 2
Place the cut outs in the left angle (between windows ‘A’ and ‘B’), bring them together until the front corners of the cardboard meet and mark with a pencil points ‘D’ and ‘E’.
Step 3
Place the cut outs in the right angle (between windows ‘A’ and ‘C’), bring them together until the front corners of the cardboard meet and mark with a pencil points ‘F’ and ‘G’.
Step 4
Measure between points ‘D’ and ‘F’ and write down as an exact measurement.
Step 5
Measure from point ‘E’ to across window ‘B’ and write down as an recess measurement.
Step 6
Measure from point ‘G’ to across window ‘C’ and write down as an recess measurement. (Note: if you have a ‘closed’ bay window i.e. you have a wall at the end of windows ‘B’ and ‘C’ opposite window ‘A’ you will need to take down the measurements for windows ‘B’ and ‘C’ as recess measurements).
