Find your ring size

Measure a ring you own

Place a ring that fits the right finger on the circles below (print at 100%, no scaling) and pick the circle that matches its inside edge. Or measure the inside diameter in millimetres and find it in the chart.

Measure your finger

Wrap a strip of paper around the base of your finger, mark where it overlaps and measure the length in millimetres: that is the circumference. Measure at the end of the day, when fingers are largest.
