About this weight

American "worsted" can mean either a yarn weight (about 18 sts / 4 in on 5 mm needles) or a yarn-spinning method (worsted-spun, where fibres are combed parallel before twisting). The two are not the same — "worsted weight" can be either worsted-spun or woollen-spun. For cables, a 3- or 4-ply, worsted-spun, smooth wool produces the crispest stitch definition.

The classic Aran sweater yarn weight. Smooth, tightly plied wool yarns produce the crispest cables.
