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 larger size. If you have big knuckles, choose the smallest size that slides over the knuckle.
