How it works
Divide the finished width by the spacing between pleats, and round up to get the number of pleats.
Each pleat uses the spacing plus twice the depth of its fold. Multiply that by the number of pleats to get the fabric width needed.
Worked example
A finished width of 40 in, with pleats 2 in apart and 1.5 in deep, needs 100 in of fabric across for 20 pleats.
Questions
What is pleat depth?
It is how far the fold runs back under the fabric. Deeper folds use more fabric for the same finished width.
Do all pleat styles work this way?
Not exactly. Box, knife and other pleats are planned differently, so check the instructions for your style.
Should I add extra?
Yes, add a little for seams and ends so the pleats still fit after the piece is finished.
