Measure a ring you already own
Place a ring that fits the intended finger on a ruler and measure the inside diameter in millimetres, edge to edge. Find the nearest diameter in the table below.
Measure your finger
Wrap a thin strip of paper around the base of your finger, mark where it overlaps, then measure the length in millimetres. This is your circumference. Measure at the end of the day when fingers are slightly larger, and make sure the ring will pass over your knuckle.
