3. Use the chart below to determine your ring size.

Measure Using Your Finger
1. Wrap a strip of paper around your finger where you’d like your ring to be. You can also use a measuring tape for this.
2. Make sure that the paper is pulled snug to your finger, the tighter the better, to find your best fit.
3. Mark the spot where the paper meets and measure the distance with a ruler or tape in mm.
4. Use the below chart to determine your ring size.
| Internal Circumference (mm) | IE/UK | US | France | EU |
