How to Choose Your Ring Size
A proper fit ensures accurate biometric sensor readings and all-day comfort.
Simple Paper Test Method:
- Cut a thin strip of paper about 8mm wide and wrap it snugly around the base of your finger.
- Mark where the paper overlaps with a pen.
- Measure the length in millimeters using a ruler, then match your measurement to the chart below.
