To ensure you get the absolute best experience from your Oura Ring 4, it’s essential to find your perfect fit. Please note that Oura Ring 4 sizes are unique and do not correspond to standard US ring sizes. We highly recommend sizing yourself with an Oura Ring 4 Sizing Kit before making your purchase; this crucial step guarantees optimal accuracy and comfort. As a bonus, purchasing a sizing kit automatically applies a $10 credit towards your Oura Ring 4 at checkout! Furthermore, unlocking the full potential of your Oura insights requires an Oura Membership. Your first month is included with purchase for new members, with subsequent access available for $5.99 per month, or an annual prepaid option of $69.99. This membership is conveniently tied to your account via the Oura App, not the physical ring itself, ensuring seamless access to your personalized health journey.
