How much yarn for a Sweater?

A standard pullover at size M takes roughly 1,400–1,800 m of worsted-weight yarn — cables or stranded colourwork can push that 30–40% higher.

Why a Sweater needs more yarn than you think

Sweater yardage surprises knitters because sleeves account for roughly 35–40% of the total — they're easy to undercount. Construction method matters too: a top-down raglan knit in the round often uses slightly less yarn than a set-in-sleeve seamed sweater, because seam allowances are absent. Ribbed hems and cuffs are about 20% denser than stockinette for the same area, so a long sweater with a deep ribbed hem can need an extra 100 m or more. Always swatch in the round if you plan to knit in the round; your flat gauge can differ by a full stitch per 10 cm.

FAQ

The questions makers ask first.

Where do the stitch coefficients come from?

They're empirical multipliers measured against stockinette (1.0). Cables and stranded colourwork eat more yarn because of the extra bulk; lace and filet use less. The numbers are averages — if your tension is unusual, drop in a real swatch in advanced mode and we'll override them.

What if I don't have a swatch?

Simple mode falls back to typical gauges for the yarn weight you picked. For wearables we still recommend a 10×10 cm swatch — once you have one, switch to advanced mode and the maths gets sharper.

Does it handle complex constructions — raglan, set-in sleeves, hoods?

The base calc is area-based. Tricky shapes (raglan, A-line, hooded) are absorbed by the 10–20% buffer; for full-body cabled sweaters or steeked cardigans we suggest pushing it to 25%.
