Ultrahuman Ring Air Sizing Kit

You have the option to choose from a diverse range of sizes from 5 to 14. Please note that we currently do not offer half sizes.

Try the size ring:
For an accurate assessment, you should wear the ring so that the engraved size number faces your palm. Important: Wear the ring for at least 24 hours to determine if it fits you.

Find the right finger:
For optimal comfort and enhanced sleep monitoring, we recommend wearing the Ultrahuman Ring AIR on your index, middle, or ring finger.

Check the fit:
There are a few simple ways to check this: When you rotate the ring on your finger, it should not spin freely.
