When choosing knitting needles or crochet hooks, be mindful of the weight of yarn you are using. Finer yarns, such as super-fine yarn, require small-diameter needles and hooks. The fatter the yarn, the larger diameter of the needles or hook you’ll need. It’s always a good idea to check the yarn label for recommended needle and hook sizes. The biggest diameter yarns, such as super bulky, should be paired with the largest needles and hooks.

*GUIDELINES ONLY: The above reflect the most commonly used gauges and needle or hook sizes for specific yarn categories.
**Lace weight yarns are usually knitted or crocheted on larger needles and hooks to create lacy, openwork patterns. Accordingly, a gauge range is difficult to determine. Always follow the gauge stated in your pattern.
***Steel crochet hooks are sized differently from regular hooks—the higher the number, the smaller the hook, which is the reverse of regular hook sizing.
