How Much Yarn for an Adult Sweater? Yardage by Weight for Knit and Crochet
An adult sweater takes roughly 1,125 to 1,625 yards of worsted weight yarn to knit and 1,400 to 2,150 yards to crochet. By size, a worsted knit sweater runs about 800 to 1,000 yards for a small, 1,000 to 1,400 for a medium and 1,400 to 1,800 for a large to XL. Buy 10 to 15 percent extra.
Published yardage guides give planning ranges for an adult sweater in fine, light, medium, bulky, super bulky yarn. In worsted weight, the most common choice, knitting takes 1,125 to 1,625 yards and crochet takes 1,400 to 2,150 yards. Crochet usually takes 25 to 33 percent more yarn than knitting because the stitches are taller and denser. Treat every figure here as a planning estimate: the yardage printed on your pattern always wins.
How much yarn for an adult sweater by yarn weight?
Yards are the reliable unit, because grams per yard change with fiber. Skeins of 100 grams and grams use the retailer yards-per-100-gram range for each weight, so a range of skeins covers both dense and lofty yarns.
| Yarn weight | Knit (yd) | Crochet (yd) | Yards per 100 g | 100 g skeins, knit | 100 g skeins, crochet | Grams, knit |
|---|---|---|---|---|---|---|
| Fine (sport) | 1,750 to 2,625 | 2,200 to 3,500 | 300 to 380 | 5 to 9 | 6 to 12 | 460 to 880 g |
| Light (DK) | 1,500 to 2,250 | 1,875 to 3,000 | 230 to 300 | 5 to 10 | 7 to 14 | 500 to 980 g |
| Medium (worsted) | 1,125 to 1,625 | 1,400 to 2,150 | 170 to 230 | 5 to 10 | 7 to 13 | 490 to 960 g |
| Bulky (chunky) | 950 to 1,125 | 1,200 to 1,500 | 100 to 170 | 6 to 12 | 8 to 15 | 560 to 1,130 g |
| Super bulky | 825 to 1,125 | 1,025 to 1,500 | under 100 | 9 or more | 11 or more | 830 g or more |
How many skeins and packs of yarn to buy for an adult sweater?

Size matters more than anything else for a garment. These worsted weight ranges come from a published yardage chart, with crochet scaled up by 25 to 33 percent. Long sleeves, a long body, cables and a loose fit push you toward the top of each range.

Why do yarn estimates for an adult sweater vary so much?
- Planning estimates only. The yardage stated on the pattern always wins.
- Crochet usually uses about 25 to 33 percent more yarn than knitting for the same size piece.
- Stitch pattern changes yardage: garter used about 46 percent more yarn than stockinette in one test; cables, textures, and colorwork use more.
- Buy 10 to 15 percent extra, from the same dye lot.
- Lion Brand ranges do not state knit or crochet; they are used here as the knit baseline.
Buy it all from one dye lot
Colors shift between dye lots, and a new lot halfway through an adult sweater can show as a stripe. Buy your full amount plus extra at once. The yarn yardage calculator works out a custom size and gauge.
Frequently asked questions
How many yards of yarn do you need for an adult sweater?
Published planning ranges for an adult sweater are 1,750 to 2,625 in fine, 1,500 to 2,250 in light, 1,125 to 1,625 in medium, 950 to 1,125 in bulky and 825 to 1,125 in super bulky yarn, in yards, for knitting. Thicker yarn covers more area per yard, so heavier weights generally need fewer yards. Crochet takes more: 1,400 to 2,150 yards in worsted. These are estimates; the yardage on your pattern always wins.
How many skeins of yarn for an adult sweater?
In 100 gram skeins of worsted, which run about 170 to 230 yards each, an adult sweater takes 5 to 10 skeins to knit and 7 to 13 to crochet. With Caron One Pound at 812 yards per skein, that is 2 to 3 skeins knit or 2 to 3 crocheted. Always count by yards on the label rather than grams, because fiber content changes how far 100 grams goes.
Does crochet use more yarn than knitting for an adult sweater?
Yes. Crochet usually uses about 25 to 33 percent more yarn than knitting for the same size piece, because crochet stitches are taller and denser. For an adult sweater in worsted that is 1,125 to 1,625 yards knit against 1,400 to 2,150 yards crocheted, a difference of up to 525 yards, or about 4 more skeins of 100 grams. Open lacy crochet stitches narrow the gap; dense single crochet widens it.
How much yarn for an adult sweater in grams?
Divide yards by the yarn's yards per 100 grams, then multiply by 100. Worsted runs about 170 to 230 yards per 100 grams, so an adult sweater knit in worsted weighs roughly 490 to 960 grams. In bulky (chunky), at 100 to 170 yards per 100 grams, it is about 560 to 1,130 grams. Grams vary with fiber: wool, cotton and acrylic in the same weight class can differ a lot in yards per gram.
How much yarn do you need for a sweater by size?
For a worsted weight pullover, published charts give about 800 to 1,000 yards to knit a small, 1,000 to 1,400 for a medium and 1,400 to 1,800 for a large to XL. Crocheted, those become 1,000 to 1,325, 1,250 to 1,850 and 1,750 to 2,400 yards. Long sleeves, a longer body, cables or a loose fit push you toward the top of each range, so check the pattern yardage for your size.
How much extra yarn should I buy for an adult sweater?
Buy 10 to 15 percent more than the estimate, all from the same dye lot, because a second lot can show as a visible stripe. For an adult sweater at the top of the worsted crochet range, 2,150 yards, that means about 2,370 to 2,480 yards in total. Garter stitch used about 46 percent more yarn than stockinette in one test, and cables, textures and colorwork add more.
