What Skirt Calculator does

Circle-skirt calculations: Calculate waist and hem radii for full, ¾, half and quarter-circle skirts.
Seam and hem allowances: Applies waist, side-seam and hem allowances to the cutting measurements.
Fabric yardage and layout: Plans panel layouts for 45-inch or 60-inch fabric and rounds yardage up.
Elastic-waist checking: Uses hip measurements to check that an elastic opening clears the hips.
Printable 1:1 pattern: Download a true-scale quarter-circle PDF for A4 or US Letter and assemble it with test squares.
Inches and centimeters: Accepts and displays measurements in inches, including fractions, or centimeters.

Who it's for

Home sewists, dressmakers and people making circle skirts, including everyday, costume, petticoat, dance and children’s skirts.

Why people use Skirt Calculator

Circle-skirt drafting requires radius, allowance, fabric-layout and yardage calculations; mistakes can lead to poor fit, wasted fabric or an uneven hem.

Enter measurements, skirt shape, closure and fabric width to get cutting radii, yardage, a grain-safe panel layout and a printable full-scale template.

It combines the calculations with a grain-safe fabric layout and a 1:1 quarter-circle PDF template with 2-inch and 5-centimeter test squares.
