Ringsizes

Find your exact size in a few simple steps — two reliable methods, a complete conversion chart.

How to measure your size

Measuring finger circumference with a paper strip, then reading the length on a ruler
  • Wrap a thin string or a strip of paper around the base of your finger (where you would wear the ring).
  • Mark the crossing point with a pen.
  • Lay it flat on a ruler and read the length in mm — that's your finger circumference.

    • Method 1 — String or paper around the finger

    Measuring the inside diameter of a ring on a millimetre ruler
  • Place a ring that fits you on a graduated ruler.
  • Measure the inside diameter from edge to edge, in mm.
  • Use the chart below to convert this diameter into a ring size.

    • Method 2 — Diameter of an existing ring
