Measure a ring you own
Lay a ring that fits the intended finger on a ruler and measure the inside edge to edge, in millimetres. Match it to the inside diameter in the table.
Measure your finger
Wrap a strip of paper around the base of the finger, mark where it overlaps, and measure the length. Match it to the circumference. Measure at the end of the day, when fingers are largest, and allow for a larger knuckle.
Between sizes
Choose the larger size for wide bands, and tell us in your order note. Many settings can be adjusted; eternity bands set all the way around usually cannot.
