History of Worsted Weight Yarn

The yarn is named for the village of Worstead in Norfolk, England. As far back as the 12th century, this town was producing smooth, even yarn and was a hub for spinning fiber. The term ‘worsted’ comes from a particular spinning method.

Wool Processing and Spinning: Worsted vs Woolen:

The word “worsted” does not always refer to a yarn weight. It can also refer to a method of processing wool — the worsted method, as opposed to the woolen method. The worsted process involves combing all the short hairs out of the fiber. The same length fibers are then spun to be parallel to each other, making a dense yarn.

Recommended Knitting Needle Sizes for Knitting With Worsted Weight Yarn:

Recommended Needle in Metric Size Range = 4.5— 5.5 mm

  1. I have trouble finding yarn that behaves as worsted wt yarn used to. And it always errors to the skimpy skinny side. My guess is that manufacturers are going for yardage and count on most people knitting scarves and Afghans

    • Hi Lynda. Thanks for sharing your thoughts. That would be disappointing. Have you found any worsted weight yarns that you love?
