Yarn Weight Standards

The Craft Yarn Council creates and sets yarn standard on commonly used gauges and needle/hook sizes. Now you can easily find the right yarn for your project based on gauge. Please note these are guidelines only - many yarns may be knitted/crocheted at a tighter or looser gauge depending on the project you'd like to create. You can find more yarn industry standards at the Craft Yarn Council.
