What Is Worsted Weight Yarn?

Worsted weight yarn also knows as aran, afghan, 10 ply, category 4 yarn that sits in the middle of the yarn weight family. It’s thicker than sock and sport weight and thinner than bulky weight yarn.

Its medium thickness means that it’s great for knitting and crocheting sweaters, hats, scarves, mittens, blankets and beyond! If you follow my crochet patterns, then you should know worsted weight yarn is my go to yarn.

Other names for worsted weight yarn

Not all worsted weight yarns are referred to by the name “worsted weight yarn”. Depending on the location, they carry different names:

  • Afghan
  • Aran
  • 10 ply yarn (UK & Australia)
  • Category 4 yarn

How To Identify Worsted Weight Yarn


Naturally, worsted weight yarn is thicker than a Category 3/Light (or DK) yarn but thinner than a Category 5/ Bulky yarn.

Crochet Hook Size

This means it comes with a special required crochet hook or knitting needles.

The recommended knitting needle size for worsted weight yarn is a US size 7 to 9 (4.5-5.5 mm), and the recommended crochet hook size is US size I-9 to K-10 1⁄2 (5.5 – 6.5 mm).

This does not have to be followed religiously, you can always go up or down a crochet hook/ knitting needle depending on the crochet project or gauge.

If you are looking to create an airy, open fabric then size up a crochet hook or knitting needle, or size down to create a tighter, sturdier fabric. As always, check your pattern to see which size needle or hook the designer recommends.

Pattern Gauge

When crocheting with worsted weight yarn, expect a gauge of 10-15 stitches per 4-inches of single crochet.

This is just an average, your gauge may differ depending on the needle/hook size you’re using and your personal tension.

And, when knitting with worsted yarn, expect a gauge of 16-20 stitches per 4-inches of stockinette stitch.

Number of Ply

Ply refers to the number of strands of yarn that are twisted together to create the finished yarn. Ply however, is not always an accurate indicator of a yarn’s thickness.

Fewer ply yarns can be thicker than more ply yarns.

With that in mind, while some countries refer to worsted yarn as 10-ply yarn (UK and Australia to he exact), it doesn’t mean it necessarily is made of 10 plies. You’ll find plenty of examples of worsted weight yarns that have between four and eight plies. 


Worsted weight yarn typically has 170-240 yards per 100g skein. The exact yardage will depend on the fibre content of the yarn. Always check the yarn label for exact details.

Advantages Of Worsted Weight Yarn


This might be the most famous reason for category 4 yarn. It works slightly faster then all the other lower categories. This yarn is just fine to work a crochet blanket, cardigans, sweaters.

Working a big project with worsted weight yarn is not ass tedious as using sport yarn.

Easy To See

If you have a poor eye sight, then you want to work with a thicker yarn. So working with category 1 yarn is not the best choice.

Crocheting at night with a dimer light can be challenging, if the yarn is thicker, light the medium yarn is, then seeing is so much easier.


Category 4 yarn allows you to make almost anything and everything from clothes, blankets, decor, amigurumis, etc.

This is not the same for fingering weight yarn. Crocheting a blanket with sport yarn is a lot of work, it can be done but it will take a while.


The yarn comes in many fabrics for multiple purposes

Great for beginners

If you are a beginner, then the perfect yarn to use in the earning journey is category 4 yarn. The yarn is easy to hold, calls for a good size yarn (5.0mm) which makes the learning curve so much easier.

How To Check For Worsted Weight Yarn

Not all yarn is labelled or called the type of yarn it is. So it is good to understand yarn labels.

The paper around the yarn usually has prints on the back. If the yarn is not labelled to be a worsted weight or DK or any yarn size, then it will have a number together with the recommended crochet hook or knitting needle sizes.
