Ring Sizing Guide
Finding your perfect fit is the first step toward a piece you'll wear every day. Use this guide to measure your ring size accurately from home.
How to Measure at Home
Use a strip of paper or string
Cut a thin strip of paper about 6 inches long, or use a piece of non-stretchy string.
Wrap around the base of your finger
Wrap snugly—not too tight—around the finger you plan to wear the ring on. Mark where the paper meets itself.
Measure the length
Lay the paper flat and measure in millimeters from start to your mark. This is your circumference.
Find your size in the chart below
Match your circumference to your US ring size using the reference chart below.

Tips for an Accurate Fit
- Measure at the end of the day when your fingers are at their largest.
- Avoid measuring when your hands are cold — fingers shrink in cooler temperatures.
- If you are between sizes, size up for wider bands and size down for thinner bands.
- Measure the finger you plan to wear the ring on — left and right hands often differ slightly.
- Take 2–3 measurements and average them for the most reliable result.
