How to Choose Your Size:

  • When measuring: Make sure the fit feels snug and measure at the base of your finger where the ring sits.

  • Stuck between two sizes? Go for the smaller size for the best snug fit and optimal readings.

  • Already own a ring? Measuring its inside diameter is the easiest and fastest way to match your size.

  • If there's a slight difference from your ring size to our chart, don't worry, most people still chooses their regular sizes and it fits perfectly.

  • Our size chart follows standard ring sizes, but slight differences in mm measurements are completely normal.
