Oura just unveiled the Ring 5, and the headline is hard to miss. The new smart ring is about 40 percent smaller than the Ring 4, which makes it look and feel much closer to a regular ring on your finger.
Underneath the slimmer shape, there are also new health features, longer battery life, and a real jump in accuracy. There is also a higher price tag and a few catches worth knowing before you click pre-order.
This guide explains the Oura Ring 5 in plain language. What is new, what is genuinely improved, what it costs, and whether it is worth upgrading from the Ring 4. No marketing fluff, just the useful parts.
Here is the short version. The Oura Ring 5 launched on May 28, 2026, and ships from June 4. It is the world’s smallest smart ring at 6.09 mm wide, starts at $399, brings new sleep, blood pressure, and breathing insights, and lasts up to seven days on a charge.
1. The Big Change: 40% Smaller, More Like a Regular Ring
The most striking thing about the Oura Ring 5 is how much less of it there is. Oura cut about 40 percent of the ring’s overall volume compared to the Ring 4, bringing it close to the look and feel of an ordinary wedding band.
The numbers tell the story:
- Width: 6.09 mm, down from 7.99 mm on the Ring 4.
- Thickness: 2.28 mm, down from 2.88 mm.
- Material: high-grade titanium, picked for strength, lightness, and kindness to sensitive skin.
- Finish: an upgraded PVD coating that resists scratches better than before, so the ring keeps its fresh look longer.
- Colors: silver, black, gold, stealth, brushed silver, and deep rose.
To squeeze everything into that smaller body, Oura’s engineers redesigned the internal sensors. According to Oura’s own teardown, the new ring uses 12 signal pathways, more efficient LEDs, and a larger photodiode for cleaner readings. Sensor domes are slightly taller than before (0.7 mm versus 0.3 mm), but a flat-top design keeps the fit subtle on your finger.
Here is the side-by-side, at a glance:
| Feature | Oura Ring 4 | Oura Ring 5 |
| Width | 7.99 mm | 6.09 mm |
| Thickness | 2.88 mm | 2.28 mm |
| Battery life | Up to 5 days | Up to 7 days |
| Overnight HRV accuracy | Baseline | 12 percent better |
| Workout heart rate signal | Baseline | 24 percent better |
| Starting price | $349 | $399 |
2. Battery and Accuracy: What Oura Improved Inside
The other big lift is what is happening underneath the titanium.
Battery life is now up to 7 days on a single charge, compared to 5 on the Ring 4. That means roughly one charge a week instead of one every few days, which makes a real difference for sleep tracking, since you do not have to plan around charging at night.
Accuracy is sharper too, according to Oura’s own numbers:
- 12% more accurate overnight HRV than the Ring 4 for the average member.
- 24% better signal quality when tracking your heart rate during a workout.
- 19% increase in accuracy for the most used activities, including running, cycling, and walking.
Those gains come from rotating the LEDs by 180 degrees to shorten the light paths, using a larger photodiode for better light reception, and pushing the sensors closer to the skin. The bigger photodiode is a quiet but important change, because more of the light bouncing back actually gets captured.
Oura’s CEO Tom Hale described it as rebuilding the ring from the inside out, designed to give people more accurate insights in a smaller, lighter body without changing the experience of wearing it.
3. New Health Features Launching With Ring 5
The Ring 5 also brings the biggest software jump in the Oura app for a long time. As TechCrunch reported at launch, many of these new features will also roll out to the Oura Ring Gen3 and later, not just the new model.
- Blood Pressure Signals. Oura tracks how your blood pressure pattern behaves while you sleep, when it should normally dip. If it does not dip as expected, the ring flags it as a possible early sign of cardiovascular strain. Available in the US, India, and the UAE from June 2026.
- Nighttime Breathing. A 30 day rolling view of your sleep-related breathing patterns and disturbances, useful for spotting changes that may relate to sleep apnea risk.
- GLP-1 Insights. A single, long term view of your medication journey for people on GLP-1 drugs like Ozempic or Wegovy, with sleep, activity, and recovery data wrapped around it.
- Live Activity Tracking. Real time tracking during workouts, so you see what is happening as it happens, not just a summary later.
- Oura Health Records. Connect your healthcare provider to bring your diagnosed conditions, medications, and lab results into the Oura app. Currently available in 43 US states.
- Improved Oura Advisor. An AI that reads your trends and gives personalised guidance, such as nudges on sleep, stress, or recovery.
Important: Oura Ring 5 is a wellness tool, not a medical device. Features like Blood Pressure Signals and Nighttime Breathing are designed to surface patterns, not to diagnose conditions. If anything in your data concerns you, speak to a doctor rather than acting on the ring alone.
4. Price, Colors, and Availability
The Ring 5 starts at $399, with the premium colors costing $499, according to coverage at 9to5Mac. That is a $50 jump from the Ring 4’s $349 starting price.
| Color | Price (US) | Look and feel |
| Silver | $399 | Classic, clean, brightest finish |
| Black | $399 | Subtle, everyday, the easiest to pair |
| Gold | $499 | Warm, premium, jewelry style |
| Stealth | $499 | Matte black, very low key |
| Brushed silver | $499 | Soft satin texture, less shine |
| Deep rose | $499 | Rose bronze, the warmest of the lineup |
Pre-orders are open now on Oura’s website, with shipping starting June 4, 2026. UK pricing is £399 and European pricing is €429 for the basic models.
Keep in mind: Oura Ring 5 still needs an Oura membership at $5.99 a month to unlock the full app features. The first month is free, and you pay monthly after that. Without the membership, the ring records data, but the deeper insights are limited.
5. Should You Buy or Upgrade?
Whether the Ring 5 is worth the money depends on which group you are in. Here is an honest take.
If you do not own an Oura Ring yet
The Ring 5 is the obvious one to pick. It is the smallest, the most accurate, and the longest lasting of any Oura ring so far, and it launches with the freshest set of health features. The starting price is steeper than the Ring 4 was, but the gap in features is real, and the size alone makes everyday wear far more comfortable.
If you already own a Ring 4
The upgrade is more of a judgement call. The size and accuracy changes are genuine. The catch is that many of the headline software features, including Blood Pressure Signals, Nighttime Breathing, GLP-1 Insights, Live Activity Tracking, and Health Records, are also rolling out to the Ring Gen3 and later through software updates. If your Ring 4 fits well and you are happy with the look, the new app features may give you most of the upgrade without buying a new ring.
Catches to know before you click buy
- Health Radar, including Blood Pressure Signals, is only available in the US, India, and the UAE at launch.
- Oura Health Records is only available in 43 US states.
- The $5.99 monthly membership is needed for the full app experience.
- Premium colors (gold, stealth, brushed silver, deep rose) cost $499, not $399.
- Sensor domes are slightly taller than on the Ring 4. Oura says the flat top design keeps it comfortable, but worth knowing.

Does the Oura Ring 5 measure blood pressure?
It does not take a direct reading like a cuff. Its Blood Pressure Signals feature looks at how your patterns behave during sleep and flags possible signs of cardiovascular strain. The feature is available in the US, India, and the UAE from June 2026.
Is the Oura Ring 5 worth upgrading from the Ring 4?
If size, comfort, or the latest accuracy and battery life matter to you, yes. If you already enjoy your Ring 4 and mostly want the new software, many of the new features are also coming to the Ring Gen3 and later through app updates, so you may get most of the upgrade without buying again.
