Worsted weight yarn, designated yarn weight symbol 4, is a popular medium-weight yarn loved for its versatility and approachable gauge. Typically worked on needles ranging from US 7 to US 9 (4.5mm to 5.5mm), worsted weight yarn is a favorite for sweaters, accessories, blankets, and everyday knitting projects. In some countries, particularly the UK, similar yarns may be described as Aran weight.
