How to Measure

1. Measure an existing ring

If you have a ring that fits well, measure the inner diameter of the ring. Match the measurement to the Diameter column in the chart above.

2. Use paper or string

Wrap a piece of string or paper around the base of your finger. Mark where the ends meet. Measure the length with a ruler (mm) and match it to the Circumference column.

Tips for Accuracy

  • Measure your finger at the end of the day when they are likely to be largest.
  • Cold weather can shrink your fingers, so ensure your hands are warm.
  • If your knuckle is much larger than your finger's base, take two measurements and choose a size in between.
  • If you are between sizes, it is usually best to size up.
