Oura Ring Gen3 Sizing Kit - Size Before You Buy Your Oura Ring Gen3 - Unique Sizing, Not Standard US Ring Sizes

OURA RING GEN3 SIZING KIT - The Oura Ring Gen3 Sizing Kit is the ideal way to find your perfect size. It is a custom sizer that allows you and those around you to find the ideal fit before you buy.

SIZE BEFORE YOU BUY – Before purchasing your Oura Ring Gen3 (which is sized differently than the Oura Ring 4), please size yourself with the Gen3 Sizing Kit. Please see the From the Brand section below for more details.
NOT STANDARD SIZING — The Oura Ring Gen3 Sizing Kit only corresponds to Oura Ring Gen3 sizes. Gen3 sizing is different from standard ring sizing. The Oura Ring Gen3 comes in sizes 6-13. There are no half sizes.

HOW IT SHOULD FIT - We recommend wearing the ring sizer for at least 24 hours to ensure the best fit. The Oura Ring Gen3 should fit snugly and comfortably at the base of your finger. The ring should not rotate when you are performing your normal daily activities.

COMFORT AND ACCURACY — A properly fitting Oura Ring Gen3 will provide the best data accuracy, comfort, and overall experience.
CHOOSE YOUR FINGER — The Oura Ring Gen3 works on any finger and can be worn on either hand. For optimal accuracy, we recommend wearing your Oura Ring Gen3 on your index finger. Please size the finger you intend to wear your Oura Ring Gen3 on.
