Features
- 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. Make sure to size the finger you plan to wear your Oura Ring on. 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 its uncomfortable. 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.
- SIZES - Oura Ring 4 is available in sizes 415, 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 youll end up receiving.

I recently used the Oura Ring 4 Gifting Sizing Kit, and I’m absolutely thrilled with how it went! The sizing kit is such a clever idea—it made finding the right fit so easy and stress-free. I was able to try on different sizes, and the whole process was simple and straightforward. I really appreciated how well-designed and user-friendly the kit was. I also love how thoughtful this kit would be as a gift. The ability to ensure the ring fits perfectly before gifting it is such a nice touch. I highly recommend this sizing kit to anyone who’s thinking about getting the Oura Ring for themselves or as a gift for someone else. It’s definitely a 5-star experience!

The product came just as described and helped to ensure I bought the correct size for my daughter. When I purchased the actual ring, they followed through and discounted the cost of the sizing kit.

The sample rings helped me test comfort and accuracy for a full day, which is great since Oura’s sizing is unique. It’s such a smart idea—especially if you’re gifting the ring—because it ensures the right size and a perfect start to the health-tracking journey.

The Oura Ring 4 Sizing Kit is very helpful and easy to use. The sizes aren’t the same as regular US ring sizes, so it’s great to try them first and find the perfect fit. The kit arrived quickly, and I appreciated that you get credit toward the actual ring purchase. Simple, accurate, and worth it!

Exactly what I needed to find the right size for an Oura ring. I ordered this just to make sure I was ordering the right size, and I'm glad I did. The Oura rings are slightly thicker than regular rings, and the thickness of the rings in this kit for sizing matched the Oura ring. My fingers tend to swell, and I used this kit to help determine what size I needed to order. But more importantly, this allowed me to wear a test ring for a few days to find which finger worked best for me. The functionality might seem unnecessary, but it really helps you gauge the best fit for yourself, while also allowing you to wear it for a couple days to make sure you like the feel of the ring. Completely worth the $10, even if it helps you decide you don't want an Oura ring.

This is such a great opportunity to try different ring sizes before actually buying the ring - especially since it’s quite expensive. Personally, I tried on several at once to see which finger felt the most comfortable. It’s ideal to wear them for a full day, since your finger size can change slightly depending on how much water is in your body. Another nice bonus - if you decide to buy the ring later, the cost of the sizing rings will be refunded. So it’s basically like getting them for free!

Unnecessary extra step. The sizing system is confusing and delays the purchase more than it should. The kit should clearly and prominently indicate which finger to use. I ended up sizing the wrong finger because this information wasn’t shown in a clear or obvious way in the kit.
