Size guide

How to measure your finger

A

Measure a ring you already have

Take a ring that fits the finger you want to wear it on. Use a ruler to measure straight across the inside — that is the inner diameter in millimetres, and it is also the ROTAS69 size. Enter it in the calculator.

B

Measure your finger

Wrap a narrow strip of paper around the base of your finger (not over the knuckle). Mark where it overlaps, straighten it and measure the length in millimetres — that is the circumference.
