Oura Ring sizes are slightly different from standard ring sizes, so it is important to size yourself using our tools and to follow our sizing instructions. The Oura Ring Sizing Kit allows for you, and those around you, to find the ideal fit before purchasing. You can also size yourself in stores where there is an Oura Ring display. A properly fitting Oura Ring will result in the highest possible data accuracy, comfort, and overall experience.
Choose a finger
The Oura Ring 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 finger.
Find your fit
Your Oura Ring should fit tightly 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
The Oura Ring is available in sizes 6–13, 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 ring sizers are made of plastic, while the Oura Ring is crafted with titanium and has a seamless inner molding 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.

Q: QuestionMy ring size is 4 1/2 to 5. What to do?(13 answers)
A: AnswerBuy a kit and try on rings until you find the one. Wear it 24 hours to see how it fits and to decide which finger you want to use. Fingers swell in the night while you sleep, so you'll want to make sure its a comfortable fit. The smallest ring is size 6 (my ring finger is a 3) and I was able to wear the sz 6 on my index finger. $10 for the ring sizer is cheap insurance to make sure you buy the right sized Oura ring, which is expensive.Answered by SandraR

Q: QuestionCan it be worn on any finger?(14 answers)
A: AnswerYes, they suggest to wear it on your index finger, but I chose not to its on my ring finger on my dominant hand. I find that I don't like to wear rings on my index it feels uncomfortable. I was worried I would just take it off and not wear it. I think the goal is to wear the ring. So far I have had no issues with the ring and data gathering.Answered by VeronicaO

Helps so much!
This is perfect if you’re in between sizes or don’t really know what size you are. The oura rings have some sensors in the inside part of the ring. These are great because it mimics the ring and sensors so you can get a feel of how the real deal will be like. Makes choosing the official ring size so much easier!

Free
Really convenient to take home the kit to make sure I ordered the right size since there were no rings in stock to try. Paid $10 and got a $10 gift card that I used toward purchase- so it was free. Hope it is accurate - I will know when I get my ring delivered.

Oura Ring Sizing Kit
The weight is not the same as the Oura Ring. Very helpful for identifying which finger is best for continuous wear. Best Buy made sizing easy. Oura makes sizing difficult. These rings are thick. I have difficulty closing my hand as I should.
