Your purchase comes with a free sizing kit for the perfect fit
Choosing the right Oura Ring size is essential for comfort and accurate readings.
Oura Ring sizing is unique in comparison to the US Standard. You’re purchasing the ring, but we’ll send you the sizing kit first at no extra cost.
Test the sample rings on your preferred finger. We recommend the index finger for optimal performance and accuracy. The middle and ring fingers are good alternatives.
Confirm your size by visiting the link on the sizing kit’s packaging, and we will ship your Oura Ring to you.
