Ring Size Guide
Find Your Perfect Fit
Not sure of your ring size? Use the guide below to find your fit before you order. If you're between sizes, we recommend sizing up.
How to Measure Your Finger
1
Cut a thin strip of paper or use a piece of string about 10cm long.
2
Wrap it snugly around the base of the finger you want to wear the ring on. Make sure it fits over your knuckle.
3
Mark where the paper or string meets. Measure that length in millimeters — that is your finger circumference.

Use the chart below to find your US ring size.

A Few Tips
- Fingers can swell during the day. Measure in the evening for the most accurate fit.
- If your knuckle is larger than the base of your finger, measure both and choose a size in between.
- Wider bands tend to fit more snugly — consider going half a size up for a wide ring.
