Pleated Skirt Calculator — Fabric Yardage for Pleats
Work out exactly how much fabric to buy for a pleated skirt — enter your waist, skirt length, number of pleats and pleat depth to get metres and yards to purchase.

How does this calculator work?
Fabric panel width = waist + (pleats × 2 × depth) + 2 × seam allowance. Divide by fabric bolt width and round up to get the number of panels; multiply by panel length (skirt + hem + seam) for total metres to buy. A typical 70 cm waist, 60 cm long skirt with 12 pleats of 3 cm depth needs about 1.5–2 m of 150 cm wide fabric.
Formula
How this is calculated
A pleated skirt requires more fabric width than your actual waist measurement because each pleat "eats" extra fabric. A knife pleat of depth d consumes 2d of fabric per pleat (the fold goes under on both sides). So the total panel width = waist circumference + (number of pleats × 2 × pleat depth) + side-seam allowances. The panel length equals the finished skirt length plus a hem allowance (typically 2–4 cm) plus a waistband seam allowance (typically 1.5 cm).
If the required panel width exceeds the fabric bolt width (commonly 112 cm / 44 in or 150 cm / 59 in), you need multiple panels sewn side by side with a seam hidden inside a pleat. The calculator divides panel width by fabric width, rounds up to the next whole panel, then multiplies by the panel length to give the total cut length to buy off the bolt.
Note that this assumes a straight (non-flared) skirt with uniform pleats distributed evenly around the waist. Accordion, box, or inverted-box pleats use different intake formulas. A box pleat consumes 4× its depth; an inverted box pleat the same. Adjust the pleat depth field accordingly if your pattern specifies a different pleat style.
Frequently asked questions
A knife or accordion pleat of 2–4 cm depth (each side) is common for skirts with moderate fullness. A 3 cm pleat with 12 pleats around a 70 cm waist adds 72 cm of pleat intake, giving a waist panel of 142 cm — about 2× the waist measurement, which provides good drape.
Plan the seam at a pleat position so the folded pleat covers it. Add an extra 1.5 cm seam allowance per panel join (already included in the side-seam allowance field). Press the seam before folding the pleat over it.
Yes — enter the box-pleat depth as the value in the "Pleat depth" field. A 5 cm box pleat (5 cm each side, meeting at the back) is equivalent to a 5 cm depth in this calculator: each pleat consumes 2 × 5 = 10 cm of fabric width.
