Patterns by Crochet Hook Sizes

Yarn hooks in the US are marked by letters from B through S, with S being the largest. Smaller hooks exist and are marked by numbers, but those steel hooks are mostly used for very fine yarn and thread, and they won't be covered here.

Yarn weights, also, are designated by numbers, and those range from 0 to 6, with 6 being the thickest and 0 being the thinnest. Each yarn weight works the best with a few different hook sizes. 

What’s the best hook size and yarn weight combination? It all depends on what you’re trying to make! If you need help choosing a crochet hook, we have a helpful guide to how to find your best crochet hook size, or you can check the yarn label when buying your yarn.

Most labels will list the recommended yarn weight, though you can still switch it up if you tend to crochet tightly or loosely or you're going after a specific effect. If you already have a yarn and hook in hand, then check out the projects that best fit your crochet hook size. 

If you'd like to learn all of the crochet terms in both UK and US terms, check out this guide!

Patterns by Crochet Hook Sizes

Technically, you can make just about any hook size work with any yarn weight, but there are certain size combinations that work better with each other, as you'll see here in this pattern collection.

For instance, a plush winter scarf is made with thicker yarn and a bigger crochet hook, like the Cozy Cowl Poncho Pattern.

On the other hand, when you’re working on something delicate, like a lace doily or the Paper Dolls Crochet Shawlette, you wouldn’t want to use anything but very fine lace yarn with a small crochet hook.

B Crochet Hook Size Patterns

B/1 hooks (UK 13, 2.25mm) fall within the range of hook sizes crochets would typically use for any projects using super fine yarn, also known as sock yarn, fingering yarn or baby yarn.

These hooks are the smallest hook sizes you can get before going into the steel hooks category for lace yarn and thread. Click for more B crochet hook patterns.

C Crochet Hook Size Patterns

Projects that use the C hook size, like the B hooks, are typically small and delicate. C/2 hook sizes (2.75mm) are used for projects that require a lot of detailing, like intricate lace designs, or smaller items, like little flowers.

You'd also choose to make socks and baby items with this combination of yarn and hook. Click for more C hook size patterns.
