Estimates assume standard tension. Always swatch first and buy one extra skein — dye lots vary and running short mid-project is painful.

How Much Yarn for Common Crochet Projects
Crochet Blanket Yarn Estimate
A worsted-weight throw (50”×60”) in double crochet needs roughly 1,600–2,200 yards — about 8–11 skeins. Denser stitches like waffle or bobble increase that by 25–50%. for size presets and cost estimates.
Crochet Sweater Yarn Estimate
An adult crochet sweater typically needs 1,000–1,800 yards depending on size and construction. DK weight works beautifully; worsted makes a heavier, warmer sweater. Always make a gauge swatch — fit depends on it.
Crochet Hat Yarn Estimate
A standard adult hat (22” circumference) uses approximately 100–200 yards of worsted — often just one skein. Slouchy hats or those with textured stitches need more. for detailed estimates.
Why Stitch Choice Matters for Yarn Usage
Single and double crochet are the baseline. Bobble and puff stitches can use 40–50% more yarn because they pull extra loops into the fabric. Waffle stitch adds 20–25%. Always select your stitch type above for an accurate estimate.
Amigurumi Yarn Estimate
A typical 6–8” amigurumi figure uses 400–600 yards of sport or DK weight with a smaller hook to create tight, stuffing-concealing fabric. Larger pieces or multi-part figures need proportionally more. Use a 2.5mm–3.5mm hook for most amigurumi. See the Amigurumi Planner.

What is the most popular yarn weight for crochet?
Worked example: A 40 × 50 inch blanket is 2,000 square inches. If your gauge swatch shows that 1 yard of yarn covers about 8 square inches, you need 2,000 ÷ 8 = 250 yards, and about 275 yards with a 10% buffer.
Common mistakes: Measure the swatch after washing and blocking, since stitches change size. Buy all your yarn from the same dye lot, and add a little extra because complex stitches use more yarn than plain ones.
