Yarn Yardage Calculator: How Much Yarn Do I Need?
Free yarn yardage calculator: how much yarn you need by project and weight — 1,125–1,625 yds for a worsted sweater — plus skeins to buy and cost.
Yarn math has real stakes: run out two inches from the end of a sleeve and the replacement skein you find may be a different dye lot that never quite matches. This calculator answers “how much yarn do I need” before you buy. Pick a project type — hat, scarf, cowl, socks, mittens, baby blanket, throw, or adult sweater — and a Craft Yarn Council weight from #1 fingering to #6 super bulky, and it returns a typical yardage range pulled from published estimator tables: 1,125–1,625 yards for a worsted adult sweater, 350–500 yards for fingering socks, 200–275 yards for a worsted hat. Enter the yards per skein printed on your label plus a price per skein, and it converts the high end of the range into skeins to buy (rounded up) and total cost. Ranges assume average adult sizes and plain stitches; cables and dense texture add 15–25%.
How much yarn do I need for a blanket?
In worsted weight: about 900–1,200 yards for a 30 × 36 inch baby blanket, 1,500–2,000 yards for a 50 × 60 inch throw, and 3,000–3,500 yards for a queen-size blanket. Bulky and super-bulky yarns cut those numbers by roughly 25–40% because thicker strands cover area faster. Add 15–25% for textured stitches like basketweave or bobbles, and round skein counts up — blankets are the easiest project to run short on.

Frequently Asked Questions
How much yarn do I need for a blanket?
In worsted weight: about 900–1,200 yards for a 30 × 36 inch baby blanket, 1,500–2,000 yards for a 50 × 60 inch throw, and 3,000–3,500 yards for a queen-size blanket. Bulky and super-bulky yarns cut those numbers by roughly 25–40% because thicker strands cover area faster. Add 15–25% for textured stitches like basketweave or bobbles, and round skein counts up — blankets are the easiest project to run short on.
How many skeins of yarn should I buy?
Divide the high end of the yardage range by the yards per skein on your label, round up, then add one extra skein from the same dye lot. Example: a worsted hat at 250 yards with 200-yard skeins is 1.25, so buy two — three if you want dye-lot insurance. The calculator does the division and rounding automatically once you enter yards per skein; the extra skein is your call.
Can I hold two strands together to substitute a thinner yarn?
Yes — two strands of fingering held together work up in the DK-to-light-worsted range, two strands of DK approximate worsted, and two strands of worsted approximate bulky. Your effective yardage halves: a 400-yard skein held double delivers about 200 yards of thicker fabric. Always swatch first, because doubled yarn often runs slightly lighter than the target category, and match the pattern’s gauge rather than trusting the label number.
