AIVELA Ring Pro sizing kit

Smart ring sizing is different.

AIVELA Ring Pro uses custom sizing that may differ from standard US ring sizes. The official kit helps you test the exact fit before choosing your final ring.

Three steps to the right fit.

01

Choose Your Finger

For the most accurate health insights and smoothest Touch experience, we recommend wearing AIVELA Ring Pro on your index finger.

02

Test for 24 Hours

Wear your preferred size throughout the day and while sleeping. Your finger size may change with temperature, movement, and time of day.

03

Confirm Your Size

Choose a fit that feels secure and comfortable. If two adjacent sizes both feel good, select the larger size for your index finger.

Secure, never restrictive.

Your sizing ring should stay comfortably in place without feeling tight. Wear it during work, rest, sleep, and everyday movement before deciding.

Feels snug and comfortable

It should stay in place without squeezing your finger.

No large gap when making a fist

The sensor area should remain close to your skin.

Remains comfortable overnight

Always test your preferred size while sleeping.

Pretty straightforward sizing kit. The different sizes made it easy to figure out what actually fits. I'd rather spend a little extra time checking than end up with the wrong size.

I almost ordered my usual ring size, but decided to try the sizing kit first. Turns out I needed a different size! Definitely worth getting before ordering the actual ring.

Super easy to use! I tried a couple of sizes and wore my favorite one overnight just to be sure. Made me feel a lot more confident about which size to order.
