Ring Sizing Guide
MEASURING YOUR FINGER
ITEMS YOU'LL NEED:
Paper or String
Scissors
Marker
- Cut out an even strip of paper or string.
- On the finger you wish to measure, wrap the paper or string around the base of the finger, just below the knuckle.
- Ensure that the paper or string is wrapped tightly around your finger for a secure fit.
- Mark the spot where it meets.
- Measure the distance with a ruler (in mm).
Voila—that’s your finger's circumference!

PRO TIPS FOR MEASURING
- Double check your knuckle measurement as some people need to size up to fit rings over knuckles.
- Throughout the day, our fingers tend to swell. Your best bet is to measure your fingers at the end of the day for the most accurate fit.
- Be sure that your hands aren’t too cold. When we’re cold, our fingers shrink in size. Measure when the temperature is just right.
