Measure a ring you already own
- Choose a ring that fits the intended finger comfortably.
- Measure the inside diameter (edge to edge) in millimetres with a ruler.
- Match the diameter to the chart below.
Or measure your finger
- Wrap a thin strip of paper around the base of your finger.
- Mark where it overlaps, then measure the length in millimetres (this is the circumference).
- Divide by 3.14 to get the diameter and match it below.
- Measure at the end of the day, when fingers are slightly larger.
