How Much Yarn Do I Need for a Blanket?

Blankets eat more yarn than any other everyday project, and they're the project where running out hurts most — a replacement skein from a different dye lot can leave a visible stripe. This chart gives you knitting yardage by blanket size and yarn weight; the numbers match the estimator inside the SkeinSense app.

Crocheting instead? Add about 25% to every number above. Standard crochet stitches consume noticeably more yarn than knit stockinette for the same fabric area.

Turning yards into skeins

Divide the total yardage by the yards printed on your skein's label, round up, then add a buffer. Example: a worsted throw needs 2,700 yds. With 220-yd skeins, 2,700 ÷ 220 = 12.3 → 13 skeins. Add a 15% dye-lot buffer for a large single-color project and buy 15.

The dye-lot rule

Every skein label carries a dye-lot number. Skeins from different lots can differ subtly in shade — invisible in the store, obvious across a blanket. Buy every skein in one trip, from one lot, and check the lot numbers at the register.
