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.
It depends on project type, yarn weight, stitch, and finished size. A worsted-weight throw blanket needs 1,600–2,200 yards; a hat needs 100–200 yards; a scarf 200–400 yards. Select your project type above and enter your dimensions for a personalized estimate.
Does the crochet stitch affect how much yarn I use?
Significantly. Bobble and puff stitches can use 40–50% more yarn than double crochet because they pull extra loops into the fabric. Triple crochet uses about 15% less than single crochet. Always factor in your stitch type when estimating.
What crochet hook size should I use?
Hook size is determined by yarn weight. Fingering uses a 2.25mm (B) hook; sport 3.5mm (E); DK 4.0mm (G); worsted 5.0mm (H); bulky 6.5mm (K); super bulky 10mm+. Always check your yarn label and swatch for any fitted project like a sweater.
How long does it take to crochet a blanket?
A worsted-weight throw in double crochet typically takes 15–25 hours. Chunky super bulky blankets can be done in 4–8 hours. The calculator estimates time based on your yarn weight and stitch type.
How much extra yarn should I buy?
Always add 10–25% for weaving in ends, gauge differences, and mistakes. Buy all yarn from the same dye lot at once — matching dye lots after running short is often impossible.
What is the most popular yarn weight for crochet?
Worsted weight (size 4) is the most popular for crochet. It works up quickly, is forgiving for beginners, is available everywhere, and suits blankets, bags, hats, scarves, and more.
