How to use this tool

  1. Enter average stitch width, round height, and rounds after center in the displayed units.
  2. Calculate and use each labeled result for crochet flat round increase check. Compare the result with a measured sample before committing materials.

Try this example

{
  "width": 0.5,
  "height": 0.4,
  "rounds": 12
}

Accuracy and scope

Ideal circumference geometry, not a universal crochet rule. Stitch construction and tension can change whether a piece lies flat.
