A classic baby set — hat, booties, and cardigan — typically needs 600–900 m of DK yarn in total, with each piece averaging 200–300 m.
Baby garments are small but the set format multiplies pieces. A newborn to 3-month cardigan uses roughly 250–350 m; a matching hat 80–120 m; booties 50–80 m each pair. The yardage per piece scales quickly: a 12-month cardigan uses 50% more yarn than a newborn one. Soft fibre matters as much as quantity — superwash merino, cotton, or bamboo blends are standard because they go through a washing machine. Avoid textured patterns on baby garments near the face; plain stockinette or moss stitch is easier to estimate and machine-wash safe. DK is the most practical weight — fine enough to be soft, chunky enough to knit up quickly.

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%) | 0.43 m² |
| S | ×0.88(-12%) | 0.48 m² |
| M | ×1.00(baseline) | 0.55 m² |
| L | ×1.14(+14%) | 0.63 m² |
| XL | ×1.28(+28%) | 0.70 m² |
| 2XL | ×1.42(+42%) | 0.78 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%.
