Ring size guide and conversion chart

Not sure about your ring size?

We design all our rings using USA ring sizing. Our ring size conversion chart below will help you find your correct size.

How to measure your ring size in mm.

  1. Use a strip of paper and wrap it around your ring finger. Make sure it fits over the knuckle.
  2. Use a pen to mark where the paper overlaps.
  3. Measure the length of the paper from the start to the pen mark using a ruler with mm measurement.
  4. Use the chart below to find your correct size.

For 100% accurate sizing, we recommend you visit your local jeweller.
