Learn how to calculate, preview, save, and print circle skirt drafts.
What is Circle Skirt Calc?
Circle Skirt Calc is a free drafting tool for planning circle skirts from quarter to double circle. Use the circle skirt calculator to turn waist, ease, finished length, allowances, fabric width, and skirt type into a draft you can check before cutting.
What you can do
- Calculate waist radius and skirt layout.
- Switch between inches and centimeters.
- Compare skirt types and fabric widths.
- Choose a skirt color for the preview.
- Save signed-in project drafts.
- Open a free HTML summary preview without signing in.
- Save a project with a free account, then generate and download its full A4 or US Letter pattern PDF in English or Chinese from the project page.
The HTML preview is a measurement summary, not an actual-size sewing pattern. For the full PDF, print at 100% scale, measure the test square, and align the tile marks. Its waist curve and straight joining edges are seam lines: add the relevant waist and joining allowances before cutting. Hem allowance is already included.
