How to measure at home
- Wrap a strip of paper or string around the base of your finger.
- Mark where it overlaps and measure the length in millimeters — that’s your circumference.
- Match it to the chart below to find your US ring size.
Tips: measure at the end of the day when fingers are largest, avoid measuring when cold, and size for the finger you’ll actually wear the ring on. For wide bands (6mm+), consider going up a half size.
