How to measure
Wrap a thin string around your finger, mark where it meets and measure in mm — that is your circumference.
🌡️
Best time to measure
Measure your finger in the evening or after exercise: fingers are slightly larger and the ring will stay comfortable all day.

Half size
If you are between two sizes, always choose the larger one, especially for wide-band rings (over 4 mm).
