All Samsung Ring sizes cost the same: $399 / £399 / around AU$750 (AU prices won’t be available until mid-October). However, there are slight differences in performance, based on ring size: the larger 12-13 sizes last for up to seven days of battery life, while the smaller sizes only last for six.

This news comes after rumors broke last week that Samsung will soon be offering size 14 and 15 options for its Galaxy Ring. According to a report from leaker Max Jambor, Samsung is set to offer the new sizes at some stage in "the coming weeks". If Jambor's report is accurate, it sounds like Samsung will beat Circular to market with the new sizing.

The smart ring landscape includes more options than ever. We compare the Ultrahuman Ring Air vs Samsung Galaxy Ring to help narrow the field.

Samsung is reportedly working on two additional sizes for the Galaxy Ring so that it fits everyone's finger without any problems.

When the Galaxy Ring made its debut in February with sizes 5 to 13, people with larger fingers were out of luck. But now Samsung is about to roll out more sizes, making the ring more inclusive for everyone (via 9to5Google) if a new tip on X from leaker Max Jambor is to be believed.

The Circular Ring Slim is the only smart ring with a haptic motor. It can be used to set timers or remind people to take medication. It weighs just 2 grams and is 2.2mm thick, making it one of the lightest and thinnest smart rings.
