NOT STANDARD SIZING - Oura Ring 5 sizes differ slightly from standard ring sizes and previous Oura Ring generations. Oura Ring 5 is available in sizes 6–13 with no half sizes.

COMFORT AND ACCURACY - A properly fitting Oura Ring 5 helps deliver the highest possible data accuracy, comfort, and overall experience.

CHOOSE A FINGER - Oura Ring 5 works on all fingers and can be worn on either hand. For optimal accuracy, Oura recommends wearing it on your index, middle, or ring finger.

HOW IT SHOULD FIT - Your Oura Ring 5 should fit securely and comfortably at the base of your finger without rotating easily during normal daily activities.

WEAR TEST - Fingers naturally expand and contract throughout the day. Oura recommends wearing the sizing ring for 24 hours to confirm your best fit.

MATERIALS - The sizing rings are made from plastic, while the final Oura Ring 5 is crafted from durable, scratch-resistant titanium for a more refined and comfortable feel.
