How to Measure
Method A — measure an existing ring
- Place a ring that fits well on a ruler.
- Measure the inside diameter in millimeters (mm).
- Match it to the chart above.
Method B — measure your finger
- Wrap a piece of string or paper strip around the base of your finger.
- Mark where it overlaps, then measure the length in millimeters.
- That length is your circumference — match it to the chart.
Sizing Tips
- Between sizes? Choose the larger size.
- Measure at the end of the day when fingers are slightly larger.
- Wide bands (6mm+) fit tighter — consider sizing up.
- Cold weather shrinks fingers slightly; warm weather expands them.
