Ring Sizing Guide

  1. Cut a strip of paper and wrap it around the finger on the hand that you want to wear the ring. Be sure that it will slide over your knuckle. 
  2. Mark the spot where the paper meets and then measure this length. This is the circumference of your finger. Refer to the right column below.
  3. Use the conversion grid below to find out what your US/AUSTRALIAN size is. Left column below.
