How to Measure
- 1Wrap a strip of paper or non-stretch string snugly around the base of your finger.
- 2Mark where the ends meet, then lay it flat against a ruler.
- 3Read the length in millimetres — that is your circumference. Match it in the chart.
- 4Or measure the inside diameter of a ring that already fits and match the diameter column.
Fit Tips
- Measure at the end of the day, when fingers are at their largest.
- Wide bands (6 mm+) fit snugly — go up a quarter to half size.
- Between sizes? Choose the larger one.
- One complimentary resize is included within the first year.
