Ring Sizing

• Which finger should I wear the ring on?

• Ultrahuman recommends either your index, middle, or ring finger.

• How do I know if the ring fits properly?
• The fit should be snug (not too tight or too loose). A few simple ways to assess this — If you rotate the ring on your finger, it should not rotate freely. To take the ring off, you must push the bottom of the ring from below and then slide it out. Pro tip: Wear the ring overnight to ensure you’re completely comfortable with it.
