When you give the gift of Oura, you want your friend or loved one to find the perfect fit. Since Oura Ring 4 sizes are slightly different from standard ring sizes and Gen3 sizes, it is important to find your size using our specific sizing kit for Oura Ring 4. This gifting kit can be paired with a gift card so that once the right size is found, the Oura Ring 4 of choice can be purchased with ease. A properly fitting Oura Ring will result in the highest possible data accuracy, comfort, and overall experience. Gift card sold separately.

• Give the gift of Oura Ring 4: This gifting kit takes the guesswork out of gifting, allowing the recipient to purchase the correct size and preferred finish of their Oura Ring 4. Gift card sold separately.
• A few easy steps: Purchase the gifting kit and a gift card with your desired value. Your friend or loved one will size themselves, and then purchase their Oura Ring 4 using the gift card.
• Choose a finger: Oura Ring 4 works on all fingers and can be worn on either hand. Make sure to size the finger you plan to wear your Oura Ring on - your fingers can be different sizes. For optimal performance and accuracy, we recommend wearing your Oura Ring on your index, middle, or ring finger.
• Find your fit: Oura Ring 4 should fit snug around the base of your finger, but not to the point where it’s uncomfortable. The right size doesn’t feel too tight during daily wear or extended periods. When sizing yourself, the ring must fit over the largest part of your finger, like your knuckle.
• Wear test: Your fingers expand and contract based on environmental factors, so we recommend wearing your ring sizer for 24 hours to confirm your best fit. Your ring should not rotate as you go about normal daily tasks. If you size in store, make sure to spend time sizing and try multiple sizes.
• Sizes: Oura Ring 4 is available in sizes 4–15, and we currently do not offer half-sizes. Oura Ring sizes are slightly different from standard ring sizes, so you should not assume your ring size.
• Materials: Our sizing rings are made of plastic, while the Oura Ring 4 is crafted in full titanium for comfort. Due to the plastic mold used to make our ring sizers, they may seem less comfortable than the actual Oura Ring you’ll end up receiving.
