Circle Skirt Calculator

A circle skirt begins with one waist measurement and ends with two marks you can actually cut: the waist radius and the outer radius. This calculator works them out for full, three-quarter, half and quarter circle skirts.

Enter your measurements and fabric width, then see how much fabric to buy, whether the folded method fits and which folds or panels to use. When you are ready, the interactive guide carries your exact result into a clear step-by-step cutting plan.

How to use it

A clear result in five steps

  1. 1Measure the exact waistline and finished length.
  2. 2Choose fullness and fabric behaviour.
  3. 3Enter usable width and allowances.
  4. 4Choose an optional separate waist finish.
  5. 5Review the result and open the exact interactive cutting guide.
Method

The maths, without the mystery

Waist stitching radius = adjusted waist ÷ (2π × fullness). Waist seam allowance moves inward to the cut radius; finished length and hem allowance extend outward to the outer cutting radius.

Questions

Frequently asked questions

Is the guide a printable pattern?

No. It is proportional cutting guidance; use a tested pattern when fit or construction demands it.

Why may a one-way print look different around the skirt?

The motif and grain rotate around circular geometry.

What if the folded method does not fit?

The result switches to a conservative panel-layout estimate.
