Not sure what size to order? Use either method below — both take less than two minutes.

Method 1: Measure a ring you already own

Grab a ring that fits the intended finger well. Measure the inside diameter in millimeters with a ruler, then match it to the closest size below.

Method 2: The string or paper strip method

1. Wrap a thin strip of paper or a piece of string snugly around the base of your finger.
2. Mark where the end overlaps, then measure that length in millimeters — that's your finger's circumference.
3. Match your circumference to the closest size below.

Keep in mind: fingers are slightly larger when warm (afternoon/evening) and smaller when cold. Your dominant hand's fingers usually run half a size larger. Wider bands fit more snugly, so if this style has a wide band, consider sizing up half a size.
