BioRingo Sizing Tips

1. Choose your finger

For the best performance and accuracy, we recommend wearing your BioRingo on your index finger. If you’d prefer another, the middle and ring fingers can work as well. Avoid fingers where the base is narrower than the knuckle.

2. Ensure a comfortable fit

The sensor bumps inside your BioRingo should be on the palm side of your finger. The BioRingo should fit securely and comfortably around your finger’s base.

3. Test the fit

Make a fist while wearing the sizing ring. If you see a gap between the top of your finger and the inside of the ring, try a smaller size.

4. Evaluate the fit

Your fingers naturally expand and contract, so we recommend wearing your sizing ring for at least 24 hours to confirm the best fit. It also shouldn’t rotate as you go about your day-to-day.
