Product information

The Ultrahuman Ring Air Sizing Kit is designed to help you find your ideal ring size. It includes ten sample rings that allow you to identify the perfect fit for your Ultrahuman Ring. Using this kit is crucial for ensuring comfort and accurate data tracking. Additionally, the kit contains high-quality plastic ring sizers ranging from sizes 5 to 14, which can be dispatched for free upon placing a Ring order.

Select the optimal finger
Begin by choosing the finger and the hand you intend to wear the ring on. Try it on your index, middle, and ring fingers to see where it fits best. It’s not recommended to wear the ring on your thumb and your little finger, as it is more accurate in your index, middle, and ring fingers.
Ensure a secure fit
Once you’ve selected a finger, position the sensor ridges on the palm side of the finger and make sure it does not rotate easily. Ensure the ring sits comfortably yet securely at the base of your finger, providing stable contact without causing discomfort. Ideally, your skin should touch the full inner circumference of the ring. If all of your skin under the ring touches it and moves along with it when you twist the ring, you have found a good fit. Once you’ve picked a size that you think fits, try a size up and a size down just to be sure.
Wear for two nights
Now that you’ve picked your size and ensured it fits you well, make sure you keep it on overnight because your fingers tend to naturally expand and contract as you go about your day. A minimum of 2 nights is recommended to ensure the ring size fits you best. It is natural for your finger size to fluctuate every day for a variety of reasons such as blood flow, fluid retention, temperature changes, and sickness. If you are a woman, even the phase of your menstrual cycle can affect your ring size. This makes it crucial to keep the ring on for two nights to check if your fit is perfect through all the changes before you submit your ring size.
Pay attention to how it feels during various tasks and at different times of the day. As the ring fit changes throughout these two days, you might notice discomfort if your finger size fluctuates significantly throughout the day. Instead of picking a looser ring to solve this, it is recommended that you find a ring that fits snugly on at least two fingers, so you can switch fingers when your finger size fluctuates. Getting a snug fit is crucial for accurate data tracking and to get the best experience of the Ring. By taking the time to find the perfect fit, you’ll ensure maximum comfort and accuracy in tracking your biomarkers in the long term.
