Here's a post on ring sizing.
Wrap a piece of loose string around your finger. Be sure to allow for the
size of your knuckle.
With a pen, mark the point on the string where the end meets.
Measure this length against a ruler or scale.
Match your results with the table below to get your ring size.
It is said that a more accurate measurement is possible in the evening.
