Worsted weight yarn is a medium weight yarn that is extremely popular with crocheters and knitters due to its versatility.

When referring to the weight of yarn, a common misconception is that it refers to the actual weight of the yarn. However, this is not the case. Yarn weight refers to the thickness of the yarn and is key in determining which type of yarn to use for a project. Worsted weight yarn is thicker than DK yarn but thinner than chunky or bulky weight yarn. For more reference on yarn weight see the standard yarn weight system chart developed by The Craft Yarn Council below.

What is the Recommended Knitting Needle and Crochet Hook Size for Worsted Yarn?

Worsted weight yarn is ideal for projects with a knitting gauge of 4–5 stitches per inch and a crochet gauge of 2.75–3.5 single crochets per inch. That usually comes out to around a 5mm knitting needle or 6mm crochet hook. It's more important to get the gauge you're looking for than it is to use a specific size tool for projects.

About Worsted Weight Yarn Plies

Yarns typically range from one-ply (single strand) to eight-ply (8 strands twisted together). Worsted weight yarn is available in a variety of ply options. When choosing yarn plies it is important to consider what your final project will be. Many crafters prefer higher number plies to avoid pilling, however, a single or lower number ply may be ideal for cushier items like a cowl or scarf.
