Much like Knitting Needles (and languages), Crochet Hooks are labelled differently in other parts of the world. On this page we have laid out a comparison table detailing the corresponding crochet hook size for each part of the world, particularly useful in understanding which size to use for different patterns.

Somewhat bemusingly, Crochet Hook sizes do differ slightly between brands, so the above table may appear slightly wrong, dependent on the brand you are familiar with.
We do hope to make this the best Crochet Hook Size Chart available anywhere on the internet, so if you have any feedback on how we could improve it, please let us know in the comments below.
