Measuring at home
- 1
Use a ring that fits
Take one that sits on the same finger and measure the inside, edge to edge, in millimetres.
- 2
Read the chart
Match that millimetre figure to the diameter column above.
- 3
Measure at the end of the day
Fingers are at their largest then, and warm. A ring that slides on in the morning may not come off at night.
