Ring Sizing Chart

How to measure your ring size for the perfect fit

Step 1: Find a ring that fits you well

Choose a ring that fits the exact finger you want the new ring for. Lay it flat on a ruler or measuring tape marked in millimetres (mm).

Step 2: Measure the inside diameter

Measure the inside edge to inside edge across the centre of the ring. This is your ring’s inside diameter. Match it to the closest size on our chart.
