Crochet Hook Sizes: A Simple Guide [Infographic]

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 we also need to make sure we have the right crochet hook size. Sometimes patterns can be incomplete and not give all the size information, and we might be unsure if what we have can work for the crochet pattern we want to make. 

Crochet hook sizes range from a B hook (2.25 mm in diameter) all the way up through the jumbo-sized S (19 mm around). If you've ever seen a crochet pattern with just the letter or just the measurement without the letter and aren't sure if you have the correct hook size, this handy printable infographic will help you keep track of everything. This crochet hook size chart also lets you visualize the size difference between each of the sizes in case you have a similar sized hook you want to use.
