Find the Perfect Fit
Oura Ring 4 Sizing Kit
Ensure you choose the perfect size. Designed specifically for the unique sizes of this smart ring, it guarantees accuracy and comfort before purchasing your definitive ring.
The ideal guide to take the first step towards your well-being with the Oura Ring 4. Ensure you choose the perfect size with the Official Sizing Kit. Specifically designed to exactly match the unique proportions of this advanced smart ring, the kit allows you to experience and accurately measure which finger you plan to wear your device on daily.
A proper fit not only maximizes your comfort level during daily use but is also of vital importance to guarantee the maximum accuracy of the health data collected by the biometric sensors of your Oura Ring 4. Although the ring can be worn on any finger, for the most accurate and consistent readings, the manufacturer recommends wearing it preferably on the index, middle, or ring finger.
Unique Oura Sizes (4 to 15)
Oura Ring 4 sizes differ slightly from conventional jewelry standards due to the space required by internal sensors. This kit is the only 100% sure way to guarantee a perfect fit, offering exact trial rings ranging from size 4 to 15.
Health Data Accuracy
The advanced sensors located inside the Oura Ring 4 need to maintain constant and firm contact with your skin. A ring that is too loose will record inaccurate sleep and heart rate data, while one that is too tight will be uncomfortable. The kit ensures you find the perfect balance.
Recommended 24-Hour Trial
Our fingers subtly change in size throughout the day due to factors such as body temperature, hydration, and physical exercise. The correct protocol is to wear the chosen trial ring continuously for at least 24 hours to confirm that it is comfortable day and night.
Instructions for Use
Follow these simple steps to ensure an optimal experience before ordering your definitive Oura Ring 4.
Try it for 24 Hours
Once you find the ring you consider ideal, wear it for a full day (24 uninterrupted hours) including your sleeping time. This will confirm that the fit remains comfortable even when fingers tend to swell or shrink.
Select with Confidence
With the exact size already verified empirically and personally, you can order your Oura Ring 4 knowing with total certainty that it will fit you perfectly and will optimally and comfortably record your health.

Frequently Asked Questions
Are Oura Ring sizes the same as regular jewelry ring sizes?
No. Oura Ring 4 sizes differ slightly from conventional jewelry standards due to the internal design that houses the advanced biometric sensors. That's why using this sizing kit is absolutely essential before placing your final order.
Which finger should I try on and wear the ring on?
You can wear the ring on the finger of your preference, but Oura engineers strongly recommend placing it on the index, middle, or ring finger to obtain the most consistent results and the highest accuracy in collecting health data through its sensors.
Why does the manufacturer insist that I wear the trial ring for 24 hours?
The size of our fingers is not static; they can naturally swell or shrink throughout the day, night, or after physical activities due to changes in body temperature. Wearing it uninterrupted for 24 hours ensures that the selected fit is comfortable and snug in any situation or circumstance of your daily routine.
