You can use one of your existing rings to find the size that fits you best:

Choose a ring that fits you perfectly.
Measure the inner diameter of the ring (from one inner edge to the other) in millimeters.
Compare the measured value with the ring size chart.

Stuck between two sizes? Always go with the larger one for maximum comfort.

In cold weather your fingers can shrink up to half a size, while in warm weather they may expand and swell.

For the most accurate result, measure your ring size at the end of the day.

Wide-band rings can feel tighter than your normal size. We recommend going one size up.
