Crochet Hook Size Conversion Chart



Crochet hook sizes can be confusing. I consider myself an intermediate crocheter and I still get mixed up. Here is a hook size conversion chart for easy reference.

When in doubt or if I don't have the right size of hook I tend to experiment and do some calculations.  Keep in mind the thicker the yarn the higher the hook.  

Another handy tool for crocheting is a ruler.  With kids in the house we have several but they disappear constantly (kind of like socks in the dryer).  Here is a fantastic link to an online ruler that adjusts to fit your screen:  Online Ruler.
