How Much Yarn Do You Need for a Crochet Blanket?

Nov 4, 2026MotifSmith

A worsted-weight throw takes about 2,900 yards in single crochet. See yardage for baby, throw, twin and queen blankets, and how to estimate your own.

A 50 by 60 inch throw in worsted-weight single crochet takes roughly 2,900 yards, including a 15% margin. A baby blanket of 36 by 45 inches takes roughly 1,560 yards, and a queen takes around 8,700. Your yarn and tension can change these figures, so treat them as a starting point.

Why blankets vary so much

  • Stitch. Dense stitches use more yarn for the same area than open ones. Filet mesh and granny squares use noticeably less.
  • Hook size. A larger hook makes looser fabric that covers more area per yard.
  • Tension. Two people with the same yarn and hook can differ a lot.
  • Colorwork. Tapestry crochet carries unused yarn inside the stitches, so it uses much more.

The most accurate way: weigh a swatch

  1. Crochet a swatch at least 6 inches square in your yarn, stitch and hook
  2. Weigh it, then divide by its area in square inches
  3. Multiply by the blanket's area for the total weight
  4. Divide by the skein weight, then add 10 to 15% for safety

Buy all your yarn from the same dye lot if you can, since shades can differ between lots.

Planning a colorwork blanket

In a chart, each color uses a different amount. MotifSmith's generator lists stitches and estimated yardage per color, so you can buy the right amount of each.
