Oura Ring 5 vs Oura Ring 4: Is the Upgrade Worth the Price 2026

The Oura Ring 5 vs Oura Ring 4 comparison has become a hot topic in the wearable tech world. Oura has launched its latest smart ring, aiming to defend its crown against aggressive rivals. But with the Oura Ring 4 still widely available and often discounted, is the newer model really worth the extra cost? We break down the key differences to help you decide.

Design and Comfort: The Biggest Leap Forward

The most striking change in the Oura Ring 5 is its dramatic slimming. The Oura Ring 4 was already sleek, but it still felt like a piece of technology on your finger. The Ring 5 reduces total volume by 40%, measuring just 2.28 mm thick. This makes it incredibly discreet and easy to wear alongside regular jewelry.

Weight has also dropped significantly. The largest Ring 5 size weighs only 2.69 grams—less than the smallest Ring 4 at 3.3 grams. If you found the previous model uncomfortable for sleep tracking, the new design solves that issue entirely.

Size Availability: A Trade-Off for Slimness

To achieve this ultra-thin profile, Oura had to make compromises. The Ring 5 is only available in sizes 6 through 13, whereas the Ring 4 offered a broader range. This means those with very small or very large fingers may need to stick with the older model.

Before ordering, be sure to check the sizing guide carefully. A proper fit is crucial for accurate sensor readings and comfort, especially since the Ring 5 is designed to be worn 24/7.

Features and Performance: What's New?

While the design is the headline, the Ring 5 also brings incremental improvements. Oura has refined its sensors and algorithms for better accuracy in sleep stages, heart rate variability, and temperature tracking. The battery life remains similar to the Ring 4, lasting up to seven days depending on usage.

However, the core experience—tracking sleep, readiness, and activity—is largely the same. Both rings sync with the Oura app, which provides detailed insights and personalized recommendations. If you're already invested in the Oura ecosystem, the upgrade is mostly about comfort and aesthetics.

Who Should Upgrade?

If you have a Ring 4 and find it bulky for sleep, the Ring 5's comfort improvements are compelling. The reduced weight and thickness make it nearly unnoticeable, which could encourage more consistent wear. However, if you're happy with your Ring 4's performance and don't mind the slightly larger profile, there's little reason to switch.

For first-time buyers, the decision hinges on budget and size. The Ring 5 offers a more refined experience, but the Ring 4 remains a capable tracker at a lower price. Those with fingers outside the 6–13 range should opt for the Ring 4. Anyone following the wider picture can start with Casio Health Ring: A Smart Ring with Activity Tracker Features.
