Ring sizes

Find your size in two minutes, with no special tools. In Europe and Portugal, the ring size equals the inner circumference in millimetres (ISO 8653).

How to measure

  1. With a paper strip: cut a narrow strip of paper (about 1 cm wide). Wrap it around the finger where the ring will sit and mark the overlap. Measure the length up to the mark in mm – that is your inner circumference. Read your size from the table.
  2. With a ring you own: take a ring that fits well and measure the inner diameter (inner edge to inner edge) in mm. Read from the table.
