How to find your ring size
Wind a piece of string or strip of paper around your finger or thumb.
Carefully mark where they meet.
Use a ruler to find the length. This is the circumference.
Divide this number by 3.14 to get the diameter.
This is the inside diameter of the ring you need.
Most of our women's rings come in standard size P.
Most of our men's rings come in standard size U.
