How to Measure
Option 1: Using an Existing Ring
Measure the inside diameter of a ring that fits comfortably and match it to the chart above.
Option 2: Measuring Your Finger
Wrap a thin strip of paper around the base of your finger. Mark where the ends meet, then measure the length in millimetres. Match this measurement to the finger circumference column.
