Circle Skirt Calculator for Sewing: Measure, Plan & Cut

Circle Skirt Calculator

What is a circle skirt?
A circle skirt is a flowing skirt cut in the shape of a circle, creating beautiful drape and movement. It can be made as a full, half, 3/4, or quarter circle, each offering a different fullness. This calculator helps you determine the waist radius and total fabric length required for your chosen style, based on your measurements and seam allowances.

How to Use the Circle Skirt Calculator

Step One: Enter your waist measurement in your preferred unit (centimeters, inches, or yards). This should be a snug measurement around where you want the skirt to sit.
Step Two: Input your desired skirt length, measuring from your waist down to where you want the hem to fall.
Step Three: Select your measurement unit. The calculator will use this unit for all calculations and results.
Step Four: Choose your preferred skirt style: full, 3/4, half, or quarter circle. Each style offers a different fullness and drape.
Step Five: Adjust the seam allowance per seam, the number of side seams, and the waistband seam allowance to match your sewing preferences. These values ensure your pattern fits perfectly and accounts for finishing.
Once all fields are filled, click “Calculate.” The calculator will display your waist radius and total fabric length, along with a detailed explanation and the formulas used. Use these measurements to draft your pattern directly onto fabric, ensuring your skirt fits and drapes exactly as planned.
