Review: Ring sizing comes in handy! - Had to buy this so I could get exact size for the Aura ring. But love it for sizing! Worth it
Review: You HAVE TO BUY OURA SIZING KIT - So happy I bought the sizing kit YOU NEED IT. Oura does not come in standard sizing. I typically wear a 7.5 US women’s ring size and the Oura size 9 was a perfect fit for my index size 8 was a bit loose on my ring finger. Shocking. So glad i didn’t purchase a 7 or an 8 or it would’ve been way to tight or loose. Your fingers swell in the morning so keep this in mind.

*by M***A on July 16, 2026*

This little sizing kit works great. Was able to get the correct size. I decided to wear the size I wanted from the kit for a few days to make sure it fit well when my hands changed throughout the day. When I finally purchased my Oura ring I had the perfect size. No issues at all.
