How to count
Wrap the yarn around a ruler or a piece of card so each wrap sits next to the last, touching but not squashed or overlapping. Count the wraps in one inch. Thicker yarn gives fewer wraps.
What the count means
| Wraps per inch | Likely weight |
|---|---|
| 30–40+ | 0 Lace |
| 14–30 | 1 Super fine |
| 12–18 | 2 Fine |
| 11–15 | 3 Light (DK) |
| 9–12 | 4 Medium (worsted, aran) |
| 6–9 | 5 Bulky |
| 5–6 | 6 Super bulky |
| 1–4 | 7 Jumbo |
These Craft Yarn Council ranges overlap, so WPI narrows the choice rather than giving one answer. Knit or crochet a gauge swatch to confirm. See yarn weight.
