After you have connected the Oura app with Health, you can control what you import and export from within the Health app.

Start by choosing your shape: Balance comes to a striking point, while Heritage keeps it smooth on top. Whatever your preference, every Oura ring has the same features and functionality, no matter the shape or color you pick. 

OURA ring is available in 8 different sizes (US6-US13). See comparison to European sizes here. 

How to choose the perfect size?

• You can wear the Oura ring on any finger, on either hand. The index, middle and ring finger usually work best.
• The ring should feel comfortable –especially in the morning when your fingers are slightly larger.
• The sensor bumps should be underneath your finger.
• When you try on the ring sizers, make sure your hands are warm.
• If you’re between sizes, it’s usually a good idea to choose the larger size. If you have big knuckles, choose the smallest size that slides over the knuckle.

You have four options to find the perfect fit:

1. Fidn out about your size at a jewelry store.
2. Use your first OURA ring as a reference. Choose the same size (size visible inside the rim).
3. Create a 3D-printed copy of the sizing kit. Download the 3D printing files. Use high quality materials. Files available here.
4. Order OURA sizing kit. Ordering the sizing kit is free for those who have ordered the ring. The sizing kit will be delivered to the postal address of your order. Once you have found out about the perfect size, just send it to us to proceed in ordering the final ring.
