Ring Size Guide

FINDING YOUR RING SIZE

TIPS AND INFORMATION

- Measure your finger in warm temperatures at the end of the day

- Different countries have different ring-size systems. All sizes listed here are standard American sizes.

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

- The average woman’s ring size is about 6.

- Your ring size will be about half a size larger on your primary hand (i.e. the hand you write with).

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

Option 2: 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).

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