Ring Sizing Guide
- 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.
- 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.
- Use the conversion grid below to find out what your US/AUSTRALIAN size is. Left column below.
