Example yarn label showing yarn weight, fiber content, and yardage

Yarn labels contain important information about the yarn you are using. This information helps you understand the yarn’s thickness, fiber content, recommended hook size, and care instructions.

Learning how to read a yarn label can help you choose the right yarn for your crochet projects and substitute yarn more confidently.

Common Information on a Yarn Label

Yarn Weight

Most yarn labels show the yarn weight category. This indicates how thick the yarn is and helps determine which crochet hook size will work best.

  • Usually shown as a number from 0 to 7
  • May also include a descriptive name such as worsted or bulky

Recommended Hook Size

Yarn labels usually include a recommended crochet hook size. This gives you a starting point for achieving the intended stitch size and fabric texture.

The recommended hook size is often based on the yarn weight, but crocheters may adjust hook size depending on personal tension or the type of fabric they want to create.

Fiber Content

The label lists the fibers used to make the yarn, often shown as percentages.

For example:

  • 100% acrylic
  • 80% acrylic / 20% wool
  • 60% cotton / 40% polyester

Yardage and Weight

Yarn labels also indicate how much yarn is included in the skein.

  • Length — usually shown in yards or meters
  • Weight — usually shown in grams or ounces

This information helps you calculate how many skeins are needed for a project.
