About Stitch Calculator

Why this site exists

A textile project often stops at a measurement question: how wide should the backing be, how many squares fit a blanket, or what size fabric should you cut? Stitch Calculator puts the inputs, result and formula together so you can check the arithmetic before using materials.

What you can do here

Use 12 free calculators for specific project decisions. The blog gives worked examples, material caveats and steps you can adapt. You do not need an account to use the tools.

How to use an estimate

Enter measurements from your own finished top, swatch or pattern. Read the assumptions below the result. Fabric selvages, grain, print repeats, seam joins, yarn gauge and finishing methods can change the amount you need. When a professional quilter or pattern provides specific requirements, use those for the final cut.
