Pleated Skirt Calculator
Determine how much fabric you need for knife, box, or inverted pleats. Calculate pleat take-up, finished width, and waistband length effortlessly.
Fabric Width Needed
81.00"
Includes seams and pleat take-up
Total Pleat Take-Up
48.00" consumed by folds
(3.00" per pleat)
Fabric & Waistband
Yardage: 1.50 yd
Waistband cut: 33.00"
How to Use This Calculator
Measure waist and choose pleat style
Decide between knife, box, or inverted pleats and measure your finished waist.
Define pleat dimensions
Enter the visible width of each pleat and how deep each fold will be.
Review fabric requirements
Use the calculated fabric width and yardage to plan cutting layout and purchase fabric.
Formula
Fabric Width = (Visible Width × Pleats) + (Pleat Take-Up × Pleats) + 2 × Seam Allowance
Pleat Take-Up = Pleat Depth × 2 (knife) or × 4 (box/inverted)
Fabric Yardage = (Fabric Width × Skirt Length) ÷ 1296
Example: 30" waist, 16 knife pleats, visible width 2", depth 1.5" → Fabric width = (2 ×16) + (3 ×16) + 1" = 81".
Yardage for 24" length = 81 × 24 ÷ 1296 ≈ 1.50 yd.

Frequently Asked Questions
Can I mix pleat styles?
Yes. Calculate each pleat style separately and sum the fabric widths to ensure you have enough material.
How do I account for lining?
For lining, use the waist measurement without pleat take-up (since lining usually hangs straight) and add hem allowances.
What if my fabric width is limited?
Split the skirt into panels. Ensure each panel includes seam allowances for joining while maintaining pleat alignment.
Should I add ease to the waist?
Pleated skirts typically align with actual waist measurement. Add 0.5" ease if you prefer breathing room or plan to layer.
