OURA RING SIZING KIT - The Oura Ring Sizing Kit is the ideal way to find the perfect ring size. It’s a custom sizer for finding the ideal fit for every Oura Ring wearer before purchasing.

RECEIVE CREDIT OF GBP 10 - With a sizing kit purchase, you will receive an Amazon credit of GBP 10 towards the purchase of an Oura Ring. The sizing kit is not returnable (terms and conditions apply)

NOT STANDARD SIZING - Oura Ring sizes are different from standard ring sizes, so it is important to size your finger using our sizing kit and to follow the instructions provided. The Oura Ring is available in sizes 6 to 13 (there are no half sizes)

HOW IT SHOULD FIT - We recommend wearing the ring sizer for at least 24 hours to confirm your best fit. The Oura Ring should fit securely and comfortably at the base of your finger, and should not rotate as you go about normal daily tasks
