Learn all about yarn weights in this beginner-friendly guide! Discover how different yarn thicknesses affect your crochet projects and which yarn weight is best for garments, blankets, and accessories.

đŸ§” What Is Yarn Weight in Crochet?

If you’ve ever wondered what “DK,” “Worsted,” or “Super Bulky” means on your yarn label, you’re not alone! Yarn weight refers to the thickness of the yarn strand, and it’s one of the most important factors in getting your crochet project just right.

Different yarn weights affect:

  • Stitch size
  • Project drape
  • Hook size
  • Time to complete the project

📊 Yarn Weights Chart: From Thread to Jumbo

Here’s a handy yarn weight chart to guide you through each type:

Jumbo0–4Home dĂ©cor, arm-knit pieces

Tip: Always check the pattern’s recommended yarn weight to avoid surprises with sizing and structure.


🔁 What Happens When You Hold Yarn Double?

A clever trick in crochet is holding two strands of yarn together to make a thicker “custom” yarn weight. Here’s what typically happens:

  • 2 strands of Fingering = Worsted
  • 2 strands of DK = Bulky
  • 2 strands of Sport = Aran

This is perfect when you don’t have the exact yarn weight a pattern calls for, or when you want to add color blending.


🎯 How to Choose the Right Yarn Weight for Your Project

Here are a few yarn weight recommendations based on project type:
