Foundation Chain Calculator

Calculate the exact number of chains needed to start a crochet project, including turning chains for each stitch type.

Turning Chain Reference

The turning chain is added at the beginning of a row to bring your hook up to the correct height for the next stitch. It is not counted as a stitch in some patterns — always check your pattern notes.

How to use

  • Enter your desired finished width and your gauge (from a swatch).
  • Select your stitch type — the turning chain count is added automatically.
  • The result shows: total chains to make = working stitches + turning chain.
  • Foundation chains are typically worked with a hook one size larger to keep them from being too tight.

Gauge can vary by hook size, yarn weight, and tension. Always crochet a swatch for accurate results.
