Crochet Hook Sizes: A Simple Guide

When working on a crochet project, we all know how important it is to make sure to pick out the best yarn for the job (link to yarn weight/type infographic), but once we've picked out our yarn, we also have to make sure to choose the best crochet hook size that goes along with that yarn type, and sometimes the information we see on our crochet patterns is confusing or incomplete.
Crochet hook sizes range from a B hook (that measure a small 2.25 mm in diameter) all the way up through the jumbo-sized S (coming in at 19 mm around). If you've ever seen a crochet pattern with just the letter as a size, or just the measurement without the letter and aren't sure if you have the right crochet hook size for the job, this handy printable infographic will help you keep track of everything.
