Ring size guide
The most reliable way to find a ring size is to measure a ring that already fits the right finger. Measure its inside diameter in millimetres and find the nearest row in the chart.
Measure at the end of the day, when fingers are slightly larger. If you are between two sizes, choose the larger one, especially for wide bands (5 mm and more).
