How do I choose a circular knitting needle size?
To calculate the maximum length of needle you can use for knitting in the round, divide the number of stitches you will be knitting by the stitch tension (gauge) per cm (or inch) to find the diameter of the knitting, and then use a needle length of that dimension or smaller.
