How do I know how much yarn I need?

Estimate the total stitches from your finished dimensions and gauge, multiply by the yarn used per stitch for your yarn weight, then divide by the yardage per skein and round up.

Should I buy an extra skein?

Yes — buy one extra skein from the same dye lot. Yarn requirements vary with tension and yarns are often discontinued, so a spare protects your project.

This is an estimate based on typical stockinette / single-crochet fabric. Textured stitches, colourwork and fringe use more, so buy an extra skein to be safe.

How this is calculated

Total area is estimated from your finished width and length.
Yarn per area is based on typical consumption for each yarn weight and whether you knit or crochet (crochet uses more).
A margin (default 15%) accounts for tension differences, swatching and edging.
Skeins round up using the yardage per skein you enter — always buy from one dye lot.
