What are the sizes of crochet thread?

Crochet threads come in many sizes, ranging from size 3 to size 100. Some are nearly as thick as yarn, while others are as thin as sewing thread. The key to understanding thread size is that the larger the number the thinner the thread.

For example: Size 3 is much larger than size 30. Conversely, size 10 is thinner than size 8 and so on.

Size 3, 5, 8, 10, 20, 30, 40 .. up to size 100

Size of the ball

When ordering crochet thread it is important to know the size and weight of ball. For example, not all size 10 thread have the same weight and yardage.

The smallest ball of thread that we carry is our Lizbeth Size 20. It is 25 grams and only 210 yards long. Why so small? Because Lizbeth specializes in tatting (see our blog on tatting for more information) so a smaller ball makes sense. The Lizbeth size 10 is also 25 grams and 210 yards long.

Next is our Alize Miss. Imported from Turkey, Alize Miss comes in size 10, and is 50 grams, 300 yards long. While the Lizbeth comes in a ball the Alize is more of a hank.

After Alize comes our Monaco Size 8, imported from the Philippines. Monaco thread is 50 grams each at 190 yards long.

Our Aunt Lydia’s Size 10 is between 300 to 400 yards long, with length depending on color. For example, White and Ecru are 400 yards long, solids are 350 yard, and mixed are 300 yards. Aunt Lydia’s size 3 is 150 yards long.

Finally, our Flax Linen is size 10 and 600 yards long.

So when choosing a crochet thread it is important to know, not only the size of the tread, but weight and length as well. If you are doing a small project such as earrings or appliques, you can use a ball with a shorter length without worrying about wasting thread. If you working on a larger project such as a shawl or table runner then the longer Aunt Lydia’s would be more economical. I wouldn’t recommend using Lizbeth for a large project.

Anyway, I hope that you found this information helpful. Thanks for stopping by our blog.
