A cowl is just a tube: circumference × height. A typical single-layer snood takes 200–350 m of worsted — but stranded colourwork nearly doubles that.
A cowl's closed-loop shape means the geometry is straightforward, but construction choices create big yardage differences. A short neck-warming cowl (20 cm high, 55 cm circumference) and a long infinity scarf that loops twice are both 'cowls' — the latter can need 3× the yarn. Double-knit cowls, worked as a two-layer tube, consume almost exactly twice the yarn of single-layer. Stranded colourwork cowls — a popular choice because the floats stay hidden inside the tube — run at the colourwork coefficient (about 1.9× stockinette), so budget accordingly. Gauge swatch in the round; circular knitting is almost always tighter than flat.

Fabric area scales from XS to 2XL. Use this to understand why larger sizes need significantly more yarn.
| Size | Area multiplier | Fabric area (m²) |
|---|---|---|
| XS | ×0.78(-22%) | 0.25 m² |
| S | ×0.88(-12%) | 0.28 m² |
| M | ×1.00(baseline) | 0.32 m² |
| L | ×1.14(+14%) | 0.36 m² |
| XL | ×1.28(+28%) | 0.41 m² |
| 2XL | ×1.42(+42%) | 0.45 m² |
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.
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.
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%.
