Free, no sign-up

Free crochet tools and calculators

Everything a crocheter reaches for mid-project, free and without signing up: count your rounds, space increases evenly, work out gauge and yarn, look up a hook size or an abbreviation, find colors that go together and price what you make.

Crochet row counter Count rounds and stitches as you go. Big buttons, saved on your phone. Increase and decrease calculator Spread increases or decreases evenly in a round, written as a pattern line. Crochet gauge calculator Turn your swatch into stitches, rows and the rounds of a flat circle. Crochet yarn calculator How much yarn a piece takes, and how many balls to buy. Crochet abbreviations Every US and UK term side by side, with what it means and how to work it. Crochet hook size chart Metric, US and UK hook sizes, and the yarn weight each one suits. Yarn weight chart and converter Yarn weights by name in every country, plus yards to meters and grams to ounces. Crochet color palette Colors that go together, each matched to a real yarn shade. Crochet pricing calculator A fair price for what you make, with your time and the platform fee included.

Made by crocheters, for crocheters

These are the same calculators that power the Yon Crochet app. They are made with amigurumi in mind but work for any crochet project, in your browser on any phone or computer, and they remember your last numbers on that device.

New to crochet? Our video lessons teach every stitch up close, and every Yon kit comes with the yarn, the hook and the lesson for your first character.

Questions crocheters ask

Are these crochet tools free?

Yes, all of them, with no account and no sign-up. They are also in the Yon Crochet app for iPhone and Android.

Do the tools work on my phone?

Yes. They are built for phones first, with big buttons and number keypads, and your numbers stay on your device.

Do the calculators use US or UK terms?

US terms by default, with UK terms one tap away where it matters, like the increase calculator and the abbreviations chart.
