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 below chart to determine your ring size.

Tips & Tricks
- 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.
- Lastly, alcohol and salt can make your fingers swell, so refrain from measuring them after cocktails and appetizers.
