How to Measure

String method: Wrap a thin string around your finger, mark where it overlaps, and measure the length in mm. Match it to the circumference column.
Existing ring: Place a ring that fits well on a ruler and measure the inside diameter in mm.
Measure at the right time: Fingers are smallest in the morning and when cold. Measure at the end of the day for the best fit.
