About

YarnWeight is a set of free tools for the question every knitter and crocheter hits eventually: what yarn is this, and what do I do with it?

The weight categories follow the Craft Yarn Council standard system. Hook and needle conversions use the standard US, UK and metric tables. Gauge ranges are the typical figures published for each category — they are ranges, not rules, and your hands will land somewhere inside them.

Every tool runs in your browser. Nothing you type is sent anywhere, there is no account, and there are no ads on the site.

Corrections are welcome — if a figure looks wrong, tell us and it gets fixed.
