The short answer
Finding the right aiRing Ultra size comes down to measuring your finger accurately and choosing a fit that feels secure without being tight. The official manual instructs users to wear the ring with its sensor positioned on the back of the finger, which means the ring should sit comfortably with the sensor flat against your skin. Because aiRing Ultra is designed for daily wear, a proper fit is essential for comfort and consistent data collection. However, specific sizing charts or a list of available ring sizes are not included in the confirmed product information, so you may need to consult the product documentation or support for exact size options.
What the evidence supports
AIHNET describes aiRing Ultra as lightweight, comfortable, and unobtrusive, designed with daily wear in mind. The manual confirms that the ring is made of stainless steel and includes sensors for temperature, acceleration, heart rate, blood oxygen, ECG, and BIA. For proper sensor function, the manual instructs wearing the ring with the sensor positioned on the back of the finger. This placement helps ensure the sensors maintain contact with your skin, which is important for the ring to capture the health metrics it supports, such as heart rate and blood oxygen.
Practical considerations
When choosing a size, consider which finger you plan to wear the ring on most often. The manual does not specify a particular finger, so you have flexibility, but remember that the sensor should sit on the back of the finger. Since aiRing Ultra is meant for daily wear, you might prefer a snug but comfortable fit that won't slide around during activities. If you are between sizes, think about whether your fingers tend to swell during the day or in warm weather; a slightly larger size might be more comfortable for all-day wear.
How to measure your finger for aiRing Ultra
- Measure at the end of the day Your fingers are typically larger later in the day, so measuring then can help you avoid a ring that feels too tight.
- Use a flexible measuring tape Wrap it around the base of the finger you plan to wear the ring on. Note the circumference in millimeters.
- Compare with a sizing guide If AIHNET provides a sizing chart, use your measurement to find the corresponding ring size. If not, contact support for guidance.
- Consider the sensor placement Ensure the ring will sit with the sensor on the back of your finger, so it should not be too loose or too tight.
