How much yarn for a sweater?

A sweater is the largest garment most knitters make, and the yardage reflects it. Underestimate and you’re chasing a discontinued dye lot with half a sleeve left to knit. Overestimate by too much and expensive yarn sits in the stash indefinitely.

The right amount depends on three things: the sweater’s size, the yarn weight, and the construction style. A cropped pullover in bulky might need 650 yards. A longline cardigan in fingering can push past 2,800. The ranges below cover the common ground.

Yardage estimates by size

These assume a standard pullover in stockinette. Crew neck, long sleeves, hip length. Cardigans, cropped styles, and textured patterns adjust the numbers (see below).

XS–S (chest 32–36 inches / 80–90 cm) Fingering: 1,310–1,640 yards DK: 985–1,310 yards Worsted: 765–1,095 yards Bulky: 600–820 yards

M–L (chest 38–44 inches / 95–110 cm) Fingering: 1,640–2,185 yards DK: 1,310–1,750 yards Worsted: 1,095–1,530 yards Bulky: 820–1,095 yards

XL–2XL (chest 46–52 inches / 115–130 cm) Fingering: 2,185–2,735 yards DK: 1,750–2,295 yards Worsted: 1,530–1,970 yards Bulky: 1,095–1,420 yards

3XL+ (chest 54+ inches / 135+ cm) Fingering: 2,735–3,280 yards DK: 2,295–2,845 yards Worsted: 1,970–2,515 yards Bulky: 1,420–1,860 yards

Style adjustments

Cardigans: Add 5–10% over a pullover of the same size. Button bands and the extra front edges consume yarn. A deeply overlapping front adds more than a narrow band.

Cropped length: Subtract 15–25%. How much depends on where the crop falls. Just below the bust saves more than just above the hip.

Tunic / longline: Add 15–25%. Every additional inch of body length adds a full row of stitches across the garment’s full width. Adds up fast.

Short sleeves or cap sleeves: Subtract 20–30%. Sleeves account for a surprisingly large portion of total yardage. Often 30–35%. Cutting most of that length is a major reduction.

Sleeveless / vest: Subtract 30–40%.

Stitch pattern adjustments

Cables: Add 15–20%. Cables pull fabric inward, so the sweater needs more stitches to achieve the same chest width. An allover cable sweater is one of the most yarn-intensive constructions there is.

Stranded colorwork: Add 20–35% across all colors combined. The floats on the wrong side consume yarn that doesn’t show on the front. A yoked colorwork sweater eats noticeably more yarn than a plain stockinette version of the same size.

Textured stitches (brioche, seed stitch): Add 10–15%. Brioche creates a double-layer fabric and can nearly double yarn consumption compared to stockinette.

Lace: Roughly the same as stockinette, or slightly less. The open structure stretches when blocked, so a lace panel covers more area per yard.

The sleeve trap

Sleeves are where yarn-estimation mistakes happen. A pair of long sleeves for an M–L sweater in worsted uses about 350–500 yards. That’s a third of the total project yardage. Knitters who estimate based on finishing the body often discover at sleeve time that they’re two skeins short.

If quantities are tight, knit the sleeves first. Counterintuitive, but practical: the body is where you can most easily adjust length if you start running low (shorten it by an inch or two), while sleeves have fixed requirements. You can’t make one shorter than the other. Knowing exactly how much the sleeves consumed gives you a clear yardage budget for the rest.

Converting yardage to skeins

Check the yarn label for yards per skein. Divide your total estimate by that number. Round up.

Your sweater needs about 1,400 yards. The yarn gives 175 yards per 50 g skein. That’s 8 skeins. Buy 9. One extra for safety.

For sweaters specifically, the extra skein is worth it even when the math seems exact. Gauge variation across the project (most knitters unknowingly tighten or loosen as they settle into a pattern), yarn used for swatching, weaving in ends, and any frogging all eat into the supply.

Working backward from stash yarn

Common scenario: you have a set amount of yarn and want to know what you can make with it.

Weigh a full skein to confirm the total weight, multiply by the number of skeins, and use the per-skein yardage from the label to calculate the total. Then check whether your yardage fits the range for the size and style you want.

If you’re on the edge (barely enough for the estimate) consider modifications that reduce yardage: shorter sleeves, a cropped body, a narrower fit. Better to plan these upfront than improvise them when the second sleeve is running low.

FAQ

How much more yarn do I need for a men’s sweater versus a women’s? The difference is size, not construction. A men’s L and a women’s L at the same chest measurement use roughly the same yarn. Men’s sweaters tend to run in larger size ranges overall, so in practice you often need more. But because the sweater is bigger, not because it’s “men’s.”

Can I use a different yarn weight than the pattern calls for? Yes, but the yardage changes substantially. Switching from worsted to DK increases total yardage by roughly 30–40% even though the yarn is thinner, because there are more stitches in every direction. The yarn substitution guide covers the full process.

How much yarn does the yoke use on a top-down sweater? The yoke typically accounts for 25–35% of total sweater yardage, depending on depth and shaping. Roughly a quarter to a third of the total for a standard round-yoke construction.

Is it better to buy extra yarn or risk running short? Always buy extra. An unused skein can be returned (many shops accept unwound returns), used for accessories, or stashed for repairs. A half-finished sweater that can’t be completed because the dye lot is gone is a much worse outcome.
