Ring Size Guide
Finding your ring size at home is easy. Here are two reliable methods.
Method 1: Measure a ring you already own
Take a ring that fits the correct finger and measure the inside diameter (edge to edge, straight across) in millimeters. Match it below.
Method 2: Measure your finger
Wrap a strip of paper or string around the base of your finger, mark where it overlaps, and measure that length in millimeters — that's your circumference.

Tips
- Measure at the end of the day, when fingers are largest.
- Wider bands fit more snugly — consider sizing up a half size for bands 6mm and wider.
- When between sizes, size up.
