About Knittster

Knittster is a small collection of free, instant calculators for the math every knitter and crocheter runs into: gauge, yarn yardage, stitch counts, and cast-ons. Every tool runs entirely in your browser - nothing you enter is sent to a server or stored anywhere.

There's no account to create and no app to download. Pick a tool, enter your numbers, and get your answer.

Knittster is ad-supported, which is what keeps every tool free with no signup required.
