The Oura Ring 5 is official. Oura is using this generation to attack the biggest smart-ring complaint first: bulk.
Oura says the new ring is 40% smaller than Oura Ring 4. It measures 6.09 mm wide and 2.28 mm thick. That matters because smart rings live or die by comfort. People need to forget they are wearing them.
The company says it rebuilt the mechanical, electrical, optical, battery, and sensing systems. This is not just a shaved-down Ring 4. It is a smaller ring with new internal architecture.
The new model is listed on Oura’s Ring 5 product page. Black and Silver start at $399. Gold, Deep Rose, Brushed Silver, and Stealth cost $499. Sizes run from 6 to 13.
What changed inside the ring
Oura is also pitching the Ring 5 as its most accurate generation yet. Redesigned low-profile sensor domes should improve skin contact. The company also says 12 signal pathways help readings across more finger types and skin tones.
Battery life is listed at six to nine days. Oura is also selling a separate charging case for travel. That could help if you hate carrying the standard charging puck.

The software side is part of the launch too. Oura is tying Ring 5 to Health Radar, GLP-1 Insights, and AI-enabled medical guidance through Counsel Health. Several features will also reach members using Oura Ring Gen3 and newer models. So this is not only a hardware lock-in play.
The buyer question is comfort versus cost
The timing is interesting for Oura. Tech My Money recently covered Oura’s confidential IPO filing. A slimmer flagship gives the company a cleaner story as smart rings become a real wearable category.
The pitch is easy to understand. Keep the health tracking, make the ring feel closer to normal jewelry, and ask buyers to pay more for the smaller design.
That last part is the caveat. The Ring 5 starts above where Oura Ring 4 launched. Oura Membership is still central to the full app experience. For existing fans who dislike chunky hardware, the redesign could be the upgrade they wanted. For everyone else, the question is price plus subscription.
