Plan your DIY pleated skirt with confidence. Enter your waist measurement, number of pleats, pleat depth, skirt length, and seam allowance to get the total fabric width and fabric length needed — so you buy exactly the right amount of material before you start cutting.

The fabric width for a pleated skirt is calculated by multiplying the fabric needed per pleat by the total number of pleats, then adding seam allowance for the side seams. Each pleat requires approximately 2–3 times its depth in extra fabric beyond the flat panel width, depending on your pleat style.
Pleat depth refers to how much fabric is folded to form each pleat — it determines how much extra material you need. Pleat width refers to the distance between pleats on the finished garment. This calculator uses pleat depth as the key input since it directly drives the fabric requirement.
A standard seam allowance of 1.5 cm (5/8 inch) is typical for most sewn seams. For side seams and waist seams, apply this to each joining edge. The patterns from this calculator do not include seam allowances in the base measurement — they are added separately so you can adjust to your preferred amount.
It is generally recommended to add at least 4 cm (1.5 inches) to the skirt length for the bottom hem. This gives you enough fabric to fold and sew a clean hem. If you prefer a deeper hem or plan to let down the skirt later, add 5–6 cm.
Making your own pleated skirt lets you customise the fit precisely to your measurements, choose any fabric you love, and control the pleat style and placement. It is also a rewarding sewing project that is relatively approachable for intermediate sewists, and often more cost-effective than buying a quality garment.
More pleats mean more fabric is needed for the width of the skirt panel, since each pleat adds folded material. Doubling the number of pleats roughly doubles the extra fabric required beyond the waist measurement. The calculator accounts for both sides of the skirt automatically.
A separate waistband piece is optional but common. It is cut as a long rectangle with a length equal to the waist circumference plus seam allowances, and a height equal to double the desired finished waistband height (so it can be folded). If you want the zipper to start below the waistband, add about 4 cm extra length to the waistband piece.
You can switch between centimetres and inches using the Units toggle at the top of the calculator. All inputs and outputs will reflect your chosen unit. Make sure all your measurements are in the same unit before calculating.
