Measure your finger

1. Wrap a strip of paper around your finger where you’d like your ring to be.

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 (mm).

Use the CIRCUMFERENCE chart to determine your ring size.

Quick Tips

- Measure your fingers at the end of the day when they’re at their largest.

- Cold weather can shrink your fingers up to half a size, so make sure they’re warm.
