Ring sizing

Not sure of your size? Measure at home in a few minutes, then use the guide below to find the Lumano size to order.

Measure your finger

  1. Wrap a strip of paper or non-stretch string around the base of the finger where the ring will sit.
  2. Mark where the paper overlaps, then lay it flat and measure the length in millimetres.
  3. Enter that measurement in the size finder below, or match it in the chart.

Measure when your hands are warm, at the end of the day. If you are between two sizes, choose the larger one.

Or measure a ring that fits

  1. Take a ring that fits the same finger comfortably.
  2. Measure the inside diameter straight across the centre (not including the band thickness).
  3. Enter the diameter in the size finder, or match it in the chart.
