Yardage maths that account for technique, stitch, size and gauge. No more notebook tables or "just buy a couple extra, to be safe."

Knitting or crochet. The choice rewires which stitches and patterns the form shows you next.
14 project types, from socks to blankets. The size scale flexes the surface area accordingly.
Yards per 100 g (or per ball). Got a gauge swatch? Drop it in for true accuracy.
Each stitch carries a real consumption coefficient. Default safety buffer is 10–20%.
A schematic of your project shows every measurement—hover any field and chest, length or sleeve lights up so you never enter the wrong number.
Just starting out? Four fields. Seasoned maker? Drop in your gauge swatch, stitch type and exact safety buffer.
One click and your skeins / metres / grams readout becomes a clean A4 you can share with the yarn store or pin to the project board.
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%.
