What Kind Of Yarn Is Worsted Weight?

Worsted yarn is medium, also labeled as a number four on skeins of yarn. It has an average crochet gauge of 2.75–3.5 stitches per inch, and a knitting gauge of 16–20 sts on US 7 to 9 knitting needles.

Of course, your gauge range depends on many factors. People have different individual gauges.

They come in many different colors.

There are so many types of yarn, so how do we number them, and do they even have numbers?

Thankfully, the US Craft Yarn Council (CYC) made our lives easier by developing a ‘Standard Yarn Weight System’ to keep yarn weights consistent.

The Standard Yarn Weight System range from numbers 0 to 7, which all yarn manufacturers adhere to when printing symbols on their labels. The weights and yarn categories made by the CYC are as follows:

  • No. 0: Lace Weight Or Crochet Thread
  • No. 1: Super Fine
  • No. 2: Fine
  • No. 3: Light (DK, Baby Sport, Baby DK
  • No. 4: Medium (a.k.a Worsted)
  • No. 5: Bulky (Aran Chunky)
  • No. 6: Super Bulky
  • No. 7: Jumbo (Sutiable for Arm Knitting)

What Is Ply?

If you look closely at a length of thread, you might notice that it appears twisted. If you untwist it far enough or pull it apart, you’ll start to see two or more strands that make up the one piece.

Those separate threads all bunched together are what people and yarn manufacturers call ‘ply.’

For example, if you went to the yarn store and picked up a ball that said “2-Ply”, that would mean it’s made up of 2 strands twisted together to make one. The same goes for 3-ply, 4-ply, and any other number of ply.

The number signifies how many strands make up one length. When you see ‘ply’ on a yarn label, just think it has 2 – or any other number said before the word ply – strands twisted together to make one.

Ply is also applicable to tissues. Whichever number listed before the word ply, 3, for example, means that it had three layers of paper bunched together.
