Measure a ring you already own
Choose a ring that fits the intended finger well. Measure the inside diameter in millimeters, edge to edge, and find the closest size below.
Measure your finger
Wrap a thin strip of paper around the base of your finger, mark where it overlaps, and measure the length in millimeters. That is your circumference. Measure at the end of the day, when fingers are slightly larger, and avoid measuring when you are cold.
Helpful tips
- Wide bands (3mm and over) fit more snugly. Consider going up half a size.
- Your knuckle matters. The ring should slide over it with slight resistance.
