Knitting Conversion Tables

Knitting Reference – Needle Sizes

Knitting needles in the UK are now sold in metric measurements. However, if you’ve inherited your great-grandmother’s knitting bag you may have needles with the old UK ratings so these have been included for your information. Where there is a gap in the table this is where there is no direct equivalent size.
