Gathered Skirt Calculator

Want to make a simple gathered skirt but don’t know how much fabric you will need? Use these calculators to determine the length and height of each piece of your skirt!

These calculators work in INCHES.

Enter your measurements and the calculators will tell you the dimensions of fabric and elastic you will need!

Seam allowances of 1/2 inch ARE INCLUDED!

Note: I have included the following gathering density options:

  • Light Gather (a 2x’s width gather)
  • Moderate Gather (a 3x’s width gather. This is a good general gathered skirt option.)
  • Heavy Gather (a 4x’s width gather)

Generally speaking, the heavier the fabric, the less of a gather it can handle. Very lightweight fabrics can handle extreme gathers of 4 times the hip circumference or more.

A 1.5 times the HIP circumference gather is possible to sew, but does not allow for comfortable walking, so it is not included in this calculator.

Disclaimer: I have done my absolute best to make sure these results are accurate, but please double check your results before cutting your material!
