Sizing Guide

Find Your Perfect Fit

AIVELA Ring Pro is available in US standard sizes 7–14. To find your best fit, we recommend using the AIVELA Sizing Kit before confirming your final size. A proper fit helps the ring stay securely on your finger, remain comfortable for day and night wear, and maintain consistent contact with your skin for more reliable health tracking.

Choose Your Wearing Finger

AIVELA Ring Pro can be worn on different fingers, depending on your comfort and preference.For the best balance of sensor performance and touch interaction features, we recommend wearing it on your:

Index finger.

Choose a finger where the ring can sit securely without feeling too tight.

Test the Fit

Your AIVELA Ring Pro should feel snug and secure, but not uncomfortable.When testing your size, the sizing ring should stay in place during normal hand movement. Try making a fist and check whether there is any noticeable gap between the ring and your finger.

A good fit should:

  • Feel secure without sliding easily 
  • Stay close to your skin 
  • Not cause pressure, pain, or numbness 
  • Be comfortable enough for all-day and overnight wear 

Please take your time when choosing your size. Since finger size may change slightly throughout the day due to temperature, activity, or hydration, we recommend wearing the sizing ring for at least24 hours before making your final decision.

Confirm Your Size

Once you have found a size that feels comfortable, stable, and suitable for both daytime and nighttime wear, you can confirm your AIVELA Ring Pro size.For the most accurate experience, please choose the size that feels secure while still remaining comfortable over extended wear.

Still unsure?

If you are between two sizes, we generally recommend choosing the size that feels more comfortable for long-term wear, especially during sleep. A ring that is too tight may cause discomfort, while a ring that is too loose may affect sensor contact and tracking consistency.
