How to measure

  1. Measure the circumference (if you do not have a ring). Wrap a piece of paper around your finger and measure it with a ruler.
  2. Measure from your current ring (diameter) by adjusting it to fit properly.
  3. Measure using a Ring Sizing Belt to obtain the circumference.
  4. Once you have the circumference, compare it with the size chart above.
