Fingering, Sport, DK, Worsted, Bulky: What Does Yarn Weight Mean?

Print Friendly, PDF & Email

Yarns come in many different thicknesses, and these yarn weights go by many different names! Worsted, afghan, and aran weight yarns all fall under the same category, while fingering weight and sock weight yarns are one and the same.

To help you keep track of what’s what, we’ve compiled a chart using the weight standards developed by the Craft Yarn Council, along with examples of Lion Brand yarns in each category.
