Master List of Crochet Hook Sizes

Crochet hook sizes matter. New crocheters may not even clue in there is a difference until they are staring at a yarn aisle and seeing all the different sizes.

Hook sizes I recommend when making a purchase for the first time. Look for 5 mm, 5.5 mm, 6 mm or 6.5 mm. For our USA friends, that size H, I, J and K.

If you are ever unsure, look at the ball band and it gives a recommendation for the hook size needed.

For beginners, I would recommend the hook sizes in red for learning.

Mikey, aka Michael Sellick, of The Crochet Crowd, started this online journey back in 2008. A mere hobby in trying to reach out to others as he was mentally struggling with his own issues. His goal was simple, find others in the yarn communities, like him, that have a common interest.

The journey and main baby of the whole idea started with a YouTube Channel and then in 2011, an official website was developed. Michael is not only the face of The Crochet Crowd but also the working engine behind the crowd in self-taught programming, social media and so much more.

Enjoy the stitching journey. Life is short, enjoy this wonderful hobby and all of the learning opportunities that come with it.
