Crochet Hook Conversion Chart
a.k.a. What size is my crochet hook?
- All listed hook sizes are based on the Craft Yarn Council’s standards, an organization worth bookmarking for all needlearts lovers! It’s important to note that there can be some inconsistency among crochet hook brands, which I noted with my knitting needles conversion chart too. Because of issues like this, I recommend always double checking your hook size using a measuring tool that includes both US and mm sizes. When designing crochet projects, I also recommend always deferring to mm sizing because it’s an objective standard of measurement. You can never be too careful with gauge!

I have a pattern that calls for 12 mm crochet hook. What letter corresponds to this size?
Heidi
No letter name is assigned to 12mm hooks. It’s actually why across needlecrafts (knit, crochet, latch hook, etc.), I personally prefer referring to metric measurements rather than the assigned letters and numbers. Gotta love how complicated measuring can be. 😅

I am making a small afghan 24″ x 36″ for the hospital patients. I am using a size K hook and need to know how many chains I need for the 24 inches then I will crochet foe 36″ long
Can you help? Thanks!
Heidi
If you have an idea of your gauge*, you can multiply the number of stitches per inch you’re working by the 24″ width. So if you’re crocheting at about 4 stitches per inch, 4 stitches per inch x 24 inches = 96 chains to begin with. Good luck!
*how many stitches per inch you’re crocheting given your tension, yarn & hook
