What’s a good Oura ring size for me?

You can wear the Oura ring on any finger, on either hand. The index, middle and ring finger usually work best.
The ring should feel comfortable –especially in the morning when your fingers are slightly larger.
The sensor bumps should be underneath your finger.
When you try on the ring sizers, make sure your hands are warm.
If you’re between sizes, it’s usually a good idea to choose the more comfortable size. If you have big knuckles, choose the smallest size that slides over the knuckle.
