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 size for your project based on gauge.
This helpful chart also allows you to compare different yarns weights. Just because a pattern states what yarn it used, doesn't mean you have to choose that yarn.
You can interchange yarns within the weight. Be sure to purchase enough yarn to complete your project.
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.
