Measure a ring she already wears
Take a ring that fits the intended finger, lay it flat and measure the inside diameter in millimetres with a ruler. Match that number to the chart below — the closest diameter is her size.

Ring size guide
Two minutes with a ruler is all it takes. Every LevSense ring is made to US 7 as standard — and any other size on request, at no extra cost.

Measure the finger directly
Wrap a thin strip of paper or a piece of string snugly around the base of the finger, mark where it meets, and measure the length in millimetres. That length is the circumference column in the chart. Measure at the end of the day, when fingers are at their largest.
