How to use this tool
- Select a size system and enter the number printed on your needle, or show the whole chart.
- Read all matching diameters. Check the actual metric measurement and knit a tension square before using a different needle.
Things to know
- US and old UK numbers are labels, not interchangeable measurements. Some US labels have several published diameters; all listed variants are shown.
- A dash means no mapping is listed in these references. This does not pick a needle for a yarn or pattern, interpolate unlisted sizes, or convert crochet hooks.
