Oura Ring 5 vs. Ring 4
| Comparison | Oura Ring 5 | Oura Ring 4 |
|---|---|---|
| Width | 6.09 mm | 7.9 mm |
| Thickness | 2.28 mm | About 2.88 mm |
| Sensor dome height | 0.7 mm | 0.3 mm |
| Photodetectors | 2 | 3 |
| Internal data storage | Up to 3 days | Up to 7 days |
| Size range | 6–13 | 4–15 |
| Features with active membership | Same feature set listed by Oura | Same feature set listed by Oura |
Oura’s published comparison shows a narrower, thinner Ring 5 body, but also a shorter internal storage buffer and fewer listed sizes. Oura says the active-membership feature set is the same across the two generations. The number of photodetectors alone does not establish which ring performs better, and the research reviewed for this article does not establish that Ring 5 is more accurate than Ring 4 in real-world use.
Oura describes Ring 5 as having “40% less volume” than Ring 4. This is Oura’s claim; the published dimensions above are a more direct way to compare the rings.
Fit, sizing and charging
Ring 5 is available in sizes 6–13, while Ring 4 covers sizes 4–15. People who need a size outside the Ring 5 range may find Ring 4 a better fit. Oura recommends using the correct Ring 5 sizing kit because sizing differs slightly between generations.

Ring 5 includes a size-specific standard charger. Oura sells a Ring 5 Charging Case separately. Confirm the exact generation and size compatibility before buying an accessory; do not assume a Ring 4 charger or case will work with Ring 5.
Features and membership
Oura says Ring 5 with an active membership includes the same feature set as Ring 4. Listed features include sleep analysis, 24/7 heart-rate tracking, temperature monitoring, blood oxygen sensing, stress and activity insights, heart-health features and women’s health insights.
Membership is linked to an Oura account rather than to a single ring. Oura says account data and benefits carry over after pairing a new ring. Check Oura’s current membership terms for pricing and details in your market.

Should you upgrade from Ring 4?
Ring 5 may suit you if:
- You want the narrower and thinner design.
- Your finger fits within sizes 6–13 and the Ring 5 sizing kit confirms a comfortable fit.
- You are buying your first Oura ring and prefer the newer form factor.
Keeping Ring 4 may suit you if:
- Your current ring fits well and meets your needs.
- You need a size outside Ring 5’s 6–13 range.
- You value Ring 4’s longer listed internal storage buffer of up to seven days.
- You are considering an upgrade mainly for software features; Oura lists the same active-membership feature set for both generations.
The clearest documented case for Ring 5 is its smaller body, not a verified jump in accuracy or a different listed feature set. Compare fit, price in your market, membership terms and the storage difference before deciding.
Verdict
Oura Ring 5 is the slimmer option in Oura’s comparison, with a 6.09 mm width and 2.28 mm thickness. Ring 4 offers a broader size range and a longer listed internal storage buffer, while Oura says both generations share the same feature set with active membership. For Ring 4 owners, fit and the physical design are the clearest reasons to consider changing rings.
