Sewing Pattern Tool
Free Circle Skirt Calculator
Calculate waist radius, fabric dimensions, hem circumference, and cutting measurements for full circle, half circle, or quarter circle skirts. This calculator helps with sewing planning for woven and stretchy fabrics.
Enter your skirt measurements
Choose the skirt type, enter your waist measurement, desired skirt length, seam allowance, and hem allowance. The calculator will estimate the waist radius and suggested fabric square size for cutting.
Formula used:
Full circle waist radius = waist ÷ (2 × π)
Half circle waist radius = waist ÷ π
Quarter circle waist radius = waist ÷ (π ÷ 2)
Cutting radius = waist radius + skirt length + hem allowance
Suggested fabric square = (cutting radius × 2) + seam allowance adjustments
Full circle waist radius = waist ÷ (2 × π)
Half circle waist radius = waist ÷ π
Quarter circle waist radius = waist ÷ (π ÷ 2)
Cutting radius = waist radius + skirt length + hem allowance
Suggested fabric square = (cutting radius × 2) + seam allowance adjustments

This circle skirt calculator provides a planning estimate. Actual pattern layout can vary based on directional fabric, fold placement, seam positioning, and whether your fabric width allows a single-piece cut.
