To place your order all you need to measure is the full width around your bay (NOT just across the bay). Then if you want the curtain to hang out of the bay on each side in the room. ***This will clear more of the bay side windows giving more light***
Add another 20 to 30cm for each return on to the size around your bay.
Basically Measuring where you would like the track to fit end to end.
This total size is what you will enter in the first box on the order form.
DON'T worry about being super accurate at this stage. Within a few cm's is fine. You will need to be more accurate when sending your final sizes. Again you don't need to worry as you will have a template to follow.
The video below gives you an overview of the ordering/measuring process.
