ULTRAHUMAN Ring AIR Sizing Kit

The Ultrahuman Sizing Kit comes with 10 high-grade mock rings to help you find the perfect Ring size. It is the only Sizing Kit that comes with true-to-life colors to help you visualize your preferred Ring color.

Size first before you buy
Ultrahuman Ring sizes differ from standard ring sizes. Purchase a sizing kit first to get the perfect ring AIR size. Ring AIR is available in 10 sizes from 5-14.

Trying the sizing ring
It is important to first use the sizing kit to determine the Ring AIR size. Wear the ring such that the engraved size number is toward the palm of your hand.

Take the two night test
Wear the Ultrahuman Sizing Kit ring over two nights or 48 hours to find your fit. This is an important step in understanding your ring size. The perfect ring size ensures that you have the most accurate readings.

Fit check
You will get highest data accuracy and optimal comfort with a properly fitting Ultrahuman Ring. Here are a few simple ways to assess this — If you rotate the ring on your finger, it should not rotate freely.

Finding the correct finger
For optimal comfort and advanced sleep tracking, we recommend you wear the Ultrahuman Ring AIR on your index, middle, or ring finger.

Color choice
With the true-to-life color swatches, you can visualize and pick the color you like.

Choose your ring
After you’ve precisely determined your size and preferred color using our sizing kit, head over to Verizon to order your Ultrahuman Smart Ring.

Build quality
While our sizing kit is made of high-grade plastic, the Ultrahuman Ring is crafted from space-grade titanium and coated with tungsten Carbide, your Ultrahuman Smart Ring promises superior quality and durability.
