Quick answer

To find your ring size, measure the circumference of your finger in millimetres or the inside diameter of a ring that fits. Indian ring size is roughly the circumference minus 40 mm, so a 52 mm finger is Indian size 12, which is about US 6 and UK L½.

How to measure

Wrap a thin strip of paper or thread around the base of your finger.
Mark where it overlaps, then measure the length in mm. That is the circumference.
Or measure the inside diameter of a ring that fits you, edge to edge, in mm.
Measure at the end of the day when fingers are slightly larger, and size up if your knuckle is wide.
