How to Find Your Correct Ring Size

1. How to Make a Paper Strip: Wrap a narrow, non-stretchy strip of paper around the finger on which you want to wear the Smart Ring.

2. Mark the spot: Mark the spot where the paper strip overlaps.

3. Measuring circumference: Lay the strip of paper flat and measure the marked length in millimeters.

4. Select size: Compare your measured finger circumference with our size chart.

Our tip: It’s best to measure your finger in the evening and several times. The ring should fit comfortably and securely, but you should be able to slide it over your knuckle without much effort.
