In order to get the correct size for you, it's advised that you order one of the Oura Ring or Samsung Galaxy Ring sizing kits before purchase. Both kits cost just $10 and that amount can be applied to your ultimate purchase of either of the rings. So getting peace of mind for the fit costs nothing. Check out the sizing kits below.

The only bummer of the Galaxy Ring is that you'll have to stay in the Samsung ecosystem if you want tracking that's truly robust.

It took Samsung three years after the launch of the Oura Ring Gen 3 to launch its smart ring, but the company managed to fix many of the Oura's problems. The Galaxy Ring is thinner, lighter, much better for swollen fingers, and has fantastic battery life. It's the best smart ring right now and a blueprint for the next Oura Ring.
