Method 1: Using a ring (Diameter)

Choose a ring that fits the intended finger.
Measure the inside diameter in millimetres.
Use the size chart to find the corresponding size.

Measure across the widest point inside the ring

Method 2: Using your finger (Circumference)

Cut a strip of paper or string.
Wrap it around your finger where the ring will sit.
Mark where the ends meet.
Measure the length in millimetres.
Use the size chart to find your size.

Do not pull the strip too tight
