Inputs are processed on this page and are never sent to a server.
For dressmakers and curtain workrooms: enter flat and finished widths, pleat count and separate edge allowances, all in mm. Finished width excludes those allowances. Each pleat takes up twice its underfold depth. Marks are measured from the left raw edge. Supports spaced or overlapping knife pleats, not box pleats or circular skirts. Test fabric thickness on a sample.
(Flat fabric width − Left edge allowance − Right edge allowance − Finished width without edge allowances) ÷ (2 × Pleat count)
40 mm
(Flat fabric width − Left edge allowance − Right edge allowance − Finished width without edge allowances) ÷ (2 × Pleat count)
40 mm
Bring A onto C with B folded underneath. Repeat in the same direction. Depth greater than finished pitch creates overlapping underfolds; the preview is not a full-size cutting pattern.

The initial choice follows your browser region. Your choice is remembered on this device. Gallons are US gallons. Switching units keeps your numbers unchanged and interprets them in the new unit.
Numbers stay unchanged. Check the new unit and enter the intended measurement, or select an example for that system.

Mistake: Changing units and assuming the entered numbers were converted.
Fix: Numbers stay unchanged. Check the new unit and enter the intended measurement, or select an example for that system.
Mistake: Treating a result as valid outside the described scope.
Fix: Bring A onto C with B folded underneath. Repeat in the same direction. Depth greater than finished pitch creates overlapping underfolds; the preview is not a full-size cutting pattern.
