Ultrahuman Ring AIR Sizing Kit – Find Your Perfect Fit

Precision Starts with the Perfect Fit

Before you commit to the Ultrahuman Ring AIR, make sure it feels like it was made for you. The Sizing Kit takes the guesswork out of smart ring shopping. For just $15, you’ll receive 10 sample ring sizes (5–14) to test at home.

Even better: That $15 comes back as a store credit — automatically applied when you order your Ultrahuman Ring AIR using the same email address.

Why the Sizing Kit Matters

  • Unique Fit – Ultrahuman rings differ from standard jewellery and other smart rings.
  • Better Accuracy – A snug fit ensures precise sleep, recovery, and activity tracking.
  • All-Day Comfort – Test before you buy to guarantee the right fit for workouts, recovery, and sleep.
  • Zero Guesswork – No wrong sizes, no delays, no exchanges.

What’s Included

  • 10 sample sizes (5–14)
  • Step-by-step instructions to guide you
  • $15 credit towards your Ultrahuman Ring AIR purchase

How to Find Your Size

  1. Try rings on different fingers and both hands.
  2. Once you find a snug fit, test a size up and down.
  3. Wear overnight—finger size changes throughout the day.
  4. The right size is when:
    • It feels snug but comfortable.
    • The sensor ridge sits on your palm side.
    • Your skin moves with the ring when rotated.

✅ No need to submit your size. Just keep your perfect fit in mind when you order your Ring AIR.

Ready to Order Your Ultrahuman Ring AIR?

When you’re confident, simply purchase your Ultrahuman Ring AIR using the same email address as your sizing kit order. Your $15 credit will automatically apply at checkout.
