How do I choose the right Oura Ring size?

Using the Oura Ring 4 Sizing Kit, choose a finger for your ring. We recommend the index, middle or ring finger. Wear the sizer ring for 24 hours to ensure the fit is secure and comfortable over the course of your day.

Oura Ring 4, Oura Ring 4 Charger, and USB-C Cable.
