Measure your finger
- Wrap a strip of paper around your finger where you’d like your ring to be.
- Make sure that the paper is pulled snug to your finger, the tighter the better, to find your best fit.
- Mark the spot where the paper meets and measure the distance with a ruler (mm).
- Use the chart to determine your ring size.

Measure your fingers when your body is not too hot or too cold.
