Are you new to crocheting? If so, you are probably wondering what yarn weight means. Yarn weight is important. The weight will affect the type of project you can make. The weight of the yarn also determines the size of the crochet hook you need.
If you are ready to dive into all things about yarn weight, continue reading. Below, I will teach you about the seven different yarn weights and what each is used for. We have also included a handy weights comparison chart for quick reference.
What is Yarn Weight?
When I started crocheting, the term yarn weight was confusing. You would think that yarn weight refers to the actual weight of the yarn. But it does not. Instead, the weight indicates the thickness of the yarn.
If you have been shopping for yarn, you have seen a number on the packaging. This number is the yarn weight. You will find yarn weight that varies from 0 lace weight to 7 jumbo.
Why is Yarn Weight Important?
So, why is yarn weight important? Weight refers to the thickness of the yarn. When making a lace project, you do not want super bulky yarn. On the other hand, you cannot make warm thick blankets with thin lace weight yarn.
Standard Yarn Weight Categories
Below, you will find the 7 main yarn weight categories. I have broken down each category, so you can have a better understanding of each type of yarn. Once you have a general understanding of each yarn weight category, take a look at the yarn weight comparison chart.

Yarn weight 0 is a very fine yarn. You will also see it referred to as lace weight yarn. This type of yarn is frequently used for making items such as lace, doilies, lightweight shawls, and more.

Yarn weight 1 is comparable to lace weight yarn. It can be used in place of it. Just remember to use the correct size crochet hook if you do. It is also referred to as super fine yarn, sock yarn, baby yarn, and fingering weight yarn. Super fine yarn is regularly used for making baby clothes, socks, lightweight shawls and scarves, and more.
