Perfect Sizing and Fit

Don't know your ring size?

It is available in 4-7 sizes. Ring diameters are expressed in US sizes 7-13. The safest way to find the correct ring size is very simple.

We strongly encourage that you refer to traditional ring sizes or take measurements at a jewelry store nearby to find your perfect fit.

Measuring process in 3 steps

Step 1 - Select a finger for your smart ring.

For the most accurate results, wear the ring on your index finger. The middle and ring fingers will also work.

Step 2 - Measure with a tape measure or refer to your traditional ring size.

Step 3 - Confirm your perfect size by comparing to the Standard Size Chart for Inner Diameter and Circumference below.
In any case, we recommend that you determine your ring size correctly, as exchanging it for a different size at a later date involves additional effort.
Also, your ring can only be exchanged if it shows no signs of wear.
