Sizing
To ensure the most accurate and comfortable fit, we highly recommend completing your order with our free and easy 2-step sizing kit.

Step 1
You’ll first receive the sizing kit. It comes with 8 plastic ring sizers, US 6 to US 13, to help you find the best fit. We recommend wearing a sizer for 24 hours. You can wear the Oura Ring on any finger, on either hand. The index, middle, and ring finger usually work best.

Step 2
Simply follow the instructions inside the sizing kit to confirm your size (online). Upon confirmation, your Oura Ring will ship within one business day.
