How to Measure

  1. Wrap a strip of paper or thread snugly around the base of your finger.
  2. Mark where the ends meet, then measure the length in millimetres.
  3. Divide this number by 3.14 (π) to find your internal diameter.
  4. Match your result to the closest size in the chart above.

For the most reliable result, we recommend measuring at the end of the day when your fingers are at their largest, and avoiding measurement in very cold conditions.

Please Note: Ring sizing is a precise process, and slight variations can occur depending on band width, metal type, and finger shape. We kindly ask that you confirm your size carefully using the guide above before placing your order.

As our rings are made and sized to order, we are unable to offer returns or exchanges for incorrect sizing. If you have any questions or need assistance choosing your size, our team is always happy to help before you order.
