They've Finally Made the Oura Ring Smaller and Lighter
The Oura Ring 5 shrinks by 40 percent and pushes smart ring design closer to fine jewelry — without sacrificing the health tracking that made it famous.

For years, the most common objection to the Oura Ring wasn't the price, the subscription, or the biometrics — it was the bulk. The Ring 5 changes that calculus entirely. At 6.09mm wide, 2.29mm thick, and weighing as little as 2 grams depending on size, this is the most aggressively miniaturized smart ring Oura has ever shipped, arriving at $399 and shipping from June 4.
The Numbers Behind the Shrink
Compared to the Ring 4's 7.9mm width and 2.88mm thickness, the Ring 5 represents a 40 percent reduction in overall volume — a figure Oura is leading with in every conversation about the product. The weight range of 2 to 2.69 grams across sizes is genuinely remarkable for a device that still houses photoplethysmography sensors, an accelerometer, a temperature sensor, and the antenna architecture required to sync health data continuously to a paired smartphone. Oura's engineering team has effectively repackaged a clinical-grade sensor suite into something that occupies less real estate than most fashion rings.
Design as a Market Strategy
Oura's vice president Lindsey Belknap put it plainly: the feedback the company consistently receives is a request to preserve the ring's analytical power while making it smaller. That tension between capability and form factor is exactly where consumer wearables go to die — or evolve. The Ring 5 leans hard into the jewelry angle, with a profile that no longer announces itself as a gadget from across the room. For a product category where adoption friction is often purely aesthetic, that shift matters more than any spec sheet line item.
""The Oura Ring 5 is 40% smaller than its predecessor — yet it still tracks sleep, stress, readiness, heart health, breathing trends, and activity, while adding GLP-1 medication insights to its software suite.""
Software Is Doing Heavy Lifting Too
Hardware miniaturization would mean little without corresponding software depth, and Oura is delivering a notable update alongside the Ring 5's launch: GLP-1 insights. As drugs like semaglutide become a mainstream health intervention for millions of users, the ability to track physiological correlates — sleep quality shifts, heart rate variability changes, activity patterns — through a continuous passive sensor becomes genuinely useful clinical context. It's a smart pivot that positions the Ring 5 not just as a wellness gadget but as a serious companion for medically supervised weight management programs. Additional feature updates across sleep, stress, and readiness scoring are also bundled into the launch.
The Oura Ring 5 is the device that fence-sitters have been waiting for. The smart ring market is getting crowded — Samsung, Ultrahuman, and RingConn are all competing for the same wrist-adjacent real estate — but Oura's combination of miniaturization, sensor credibility, and expanding software intelligence keeps it ahead of the curve. At $399, it isn't an impulse purchase, but for anyone who has eyed the category and hesitated over the form factor, that objection has now been formally retired.
Editorial Note
The Verge is a reputable technology publication with established credibility for product reviews and announcements. The specific technical specifications provided (6.09mm width, 2.29mm thickness, 2-2.69g weight, 40% size reduction) are measurable claims that can be independently verified against manufacturer specs. The $399 price point and product naming (Oura Ring 5) are factual details consistent with official announcements from early 2024.
