How to Measure Ring Size at Home: The 3-Minute Method

A wrong ring size is the most common — and most avoidable — ring mistake.

Method 1: Existing ring

Measure the inside diameter of a ring that fits, in millimetres, and match it to our size chart.

Method 2: String or paper

Wrap a strip around the finger, mark the overlap, and measure the length in millimetres.

Tips

• Measure at the end of the day — fingers swell.
• Measure in warm conditions.
• Wider bands fit tighter — go up half a size for bands over 6mm.
