The Oura Ring 5 represents a massive generational leap for smart rings, delivering a dramatic 40% reduction in overall volume compared to the Ring 4. It shrinks down to just 6.09mm wide and 2.28mm thick, weighing a featherlight 2g to 2.7g. The result is a device that finally looks, feels, and wears like a classic wedding band rather than a piece of bulkier tech.
Despite the ultra-slim frame, Oura upgraded the internal hardware. The interior sensor domes feature a flatter, low-profile design that makes better skin contact without digging into your finger. While light pathways were consolidated from 18 down to 12, the new LEDs are 4x brighter, driving up to a 19% increase in workout tracking precision and 12% higher overnight HRV accuracy. Additionally, the new Health Radar system brings continuous background monitoring and early trend detection for vitals.
