Oura Ring 5 design and features
The biggest change with the Oura Ring 5 is its design. It measures 6.09mm wide, down from 7.99 on the Oura Ring 4. It’s 2.29mm thick, down from 2.88mm. This is a dramatic reduction in overall size, addressing one of the biggest complaints of previous Oura Ring generations. In images, it now looks much closer to a traditional wedding band size.
By redesigning the mechanical, electrical, optical, battery, and sensing architectures, Oura achieved the most refined silhouette yet: thinner and lighter, with a smoother curvature engineered to feel completely natural on the finger. That shift in size makes Oura Ring even more desirable to a broader audience, especially for those who have wanted a truly discreet form factor.
