How to measure

Wrap a thin string around your finger, mark where the ends meet and measure in mm: this is your circumference.

The right time

Measure your finger in the evening or after physical activity: it is slightly larger, so your ring will remain comfortable throughout the day.

Between sizes

If you are between two sizes, choose the larger one, especially for wide bands (over 4 mm).
