Have a ring that fits? Measure straight across the inside, edge to edge, in millimeters and match it to Inside diameter.
No ring? Wrap string or a paper strip around the base of your finger, mark where it overlaps, and measure the length in millimeters. Match it to Finger circumference. Measure at the end of the day, and make sure it fits over your knuckle.
Tip: If you're between sizes, choose the larger size.
Wipe with a soft cloth. Skip water, perfume, and lotion.
