yarn weight/thickness

Knitting and crochet yarns come in different weights, or thicknesses. The thickness of your yarn (among other factors) has a huge impact on the look of your knitted or crocheted fabric — and certainly the amount of time it takes to complete it. Yarn weight determines how many stitches it takes to knit 1 inch.

Although there are no official categories for yarn weights, many knitting books and yarn manufacturers use common terms to indicate a yarn’s thickness and the size of the needle with which you work on the yarn.


The thickness of a given yarn is determined by the individual thickness of the plies, not by the number of plies. If the plies are thin, a 4-ply yarn can be finer than a heavy, single-ply yarn.
