About this weight

British knitters call this weight DK or 8-ply; Australians call it 8-ply; Americans split it from worsted by gauge. A DK yarn at 22 sts to 4 inches on 4 mm needles is the textbook standard. The vast majority of free patterns on this site list a DK or worsted recommendation.

DK is the most-knit weight in the UK and one of the most popular worldwide. Choose a smooth, plied yarn for cables; a softer single-ply for next-to-skin.
