In short
Ring 5 is the smallest current Oura: 6.09 × 2.28 mm titanium, sizes 6–13, typically 6–9 days, same membership software family as Ring 4. Buy it if you fit 6–13 and will pay membership. Skip it if you need sizes 4–5 or 14–15 (still a Ring 4 run) or you refuse a subscription.
Who it is for
- Sleep- and recovery-first buyers who will pay Oura Membership and want the smallest current Oura.
- People who already have an Oura account — membership is account-tied, not ring-tied, and carries to Ring 5.
- Buyers who fit sizes 6–13 and want titanium + superhard PVD in six finishes.
- iPhone or Android users (Oura App: iOS 16+ or Android 11+ with Google Play and Bluetooth 5.0).
Who should skip it
- Anyone who needs sizes 4–5 or 14–15. Ring 5 is 6–13 only; Ring 4 still lists 4–15.
- Buyers who will not pay membership. Without it, Oura says you only see the three daily scores, battery, profile, settings, and Explore.
- People shopping a no-subscription ring with a 10–15 day OEM battery table (RingConn / Ultrahuman PRO).
- Anyone who wants a sports GPS watch. Oura is a ring with automatic activity detection, not a multi-band GNSS clock.
Key differentiators
- Smallest current Oura: 6.09 mm wide, 2.28 mm thick, 40% less volume than Ring 4 (Oura).
- Typically 6–9 days and ~80 minute charge despite the smaller shell.
- Same membership feature list as Ring 4 (sleep, 24/7 HR, Stress, Heart Health, Women's Health, SpO2). Health Radar / Counsel Health / GLP-1 Insights are described as Gen3-and-newer software, not Ring-5-only scores.
- Optional Ring 5 Charging Case (sold separately): Oura says up to one month of battery and a full day of charge in about 10 minutes.
Caveats
- Every battery, accuracy, and “world’s smallest” line is an Oura claim. GadgetShowdown has not worn or lab-tested Ring 5.
- Sizing kits are generation-specific. Oura: Ring 5 kit is white sizers 6–13; do not reuse a Ring 4 kit.
- On-ring memory is up to three days vs up to seven on Ring 4 — shorter offline buffer.
- This environment can flip Oura geo. 2026-09-19: morning US-facing store from $399 / $499; one evening pull resolved to euros (from €429); a later evening re-pull showed US dollars again (from $399 / $499); a 4:20 PM ET re-pull of /store flipped to euros again (Ring 5 from €429); a ~4:45 PM ET re-pull showed US dollars again (Ring 5 from $399 / $499). US price cells stay on the same-day USD grid. Re-open the US shop on quote day.
- Oura’s General FAQs / Product Safety (2026): Oura Ring is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent medical conditions.

Overview
Oura Ring 5 is the May 2026 Oura. Oura’s own framing is “the world’s smallest smart ring”: 6.09 mm wide, 2.28 mm thick, 40% less volume than Ring 4, titanium with superhard PVD, six finishes, sizes 6–13. The software story is membership, not a new score SKU — support says Ring 5 with active membership includes the same feature list as Ring 4.
This hub exists so later ring writers can clone one compact record. The first spec table is rings-v1. Comparison URLs, when written, stay on their own -vs- slugs. This page’s public path is locked at /rings/oura-ring-5/.
We have not worn the ring. Superlatives stay labeled as Oura claims.
Sensors, sleep, and activity
Support lists two tri-LED emitters, two photodetectors, a digital temperature sensor, and an accelerometer. The blog adds 12 signal pathways and “most accurate generation yet.” Sleep analysis, SpO2, 24/7 HR, Stress, Heart Health, Metabolic Health, and Women’s Health are membership features. Automatic Activity Detection is not a sports-watch GNSS stack.
Battery and charging
| OEM claim | Ring 5 |
|---|---|
| Typical life | 6–9 days |
| Charge | About 80 minutes |
| In the box | Size-specific charger + USB-C |
| Optional case | Up to one month; ~10 minutes ≈ a full day (Oura) |
| Memory | Up to 3 days |
Do not invent a measured “we got 7.2 days” sentence.
App, subscription, and platforms
Oura App on iOS 16+ / Android 11+. US membership is $5.99 / month or $69.99 / year as of the 8 September 2026 support article. Account-tied. Without membership, three scores only.

Frequently asked questions
Does Ring 5 work without Oura Membership?
The ring still collects data, but Oura says that without membership you only see the three daily scores, battery, profile, settings, and Explore. Full sleep analysis, 24/7 HR detail, Stress, Heart Health, Women’s Health, and the API need an active membership. New members get one complimentary month. Membership is tied to the Oura account, not the physical ring.
Can I use Ring 5 with Android?
Yes. Oura’s setup articles list iOS 16 or later and Android 11 or later with Google Play services, plus Bluetooth 5.0 on the phone. It is not Galaxy-phone-locked.
Why not buy leftover Ring 4?
Ring 4 is still on the US store (from $349 on 2026-09-19) and still covers sizes 4–15. Ring 5 is smaller (6.09 × 2.28 mm vs 7.9 × ~2.88 mm) with a 6–9 vs 5–8 day battery claim and only three days of onboard memory. Software features are the same membership set. Extreme sizes and leftover price are the honest Ring 4 reasons.
Are Oura’s accuracy percentages independent tests?
No. The store’s 99% heart-rate and 95% sleep-staging lines are Oura claims with footnotes to Oura’s own validation write-up and a 2021 Sensors paper. We repeat the claim; we did not reproduce it.
