For Oura Ring to bring the result with accurate precision it is vital that size of your ring is one that fits you.

Information You're Finding!

Oura Rings comes in variety of sizes but you can get good hang about it through the ring kit from Oura or manually measure your finger through handmade rope.

Get The Oura Ring Sizing Kit!

So the easiest way to get the right measurement idea is through the ring kit. Now problem is that Oura doesn’t sell it anymore, you would’ve to buy the Oura Ring to get your hands on it. Although, if you know someone in your friends or family who did recently got Oura product then you should probably ask them. There is good chance they would’ve come across one not long ago.

“What if I don’t know anyone like that?”

– Anyone could ask this question

If you’re someone like that then there are two more options that you could go for:

  • Go to your nearest Best Buy or Therabody store and you will get the kit there to find your perfect fit.
  • Another option is to actually buy the Oura Ring kit from the Best Buy (we have included the ring below).

However, the dilemma is that not everyone lives in the U.S so not everyone will have the access to it. In which case what do you think you could do? For example I live in the UAE and here there is no Best Buy, what do you think I will do? Or anyone like me can do?

Umm…

Use The Kit Ring To Get Measurement Idea

For someone who can’t get their hands on the Oura Ring kit we’ve something for you which could help you out. It is not how the physical counterpart of it would’ve been, but for now it will work.

Ring Number Ring’s Diameter Inner Diameter
Size 6 16.76 mm 15.21 mm
Size 7 17.60 mm 15.97 mm
Size 8 18.43 mm 16.81 mm
Size 9 19.25 mm 17.63 mm
Size 10 20.02 mm 18.41 mm
Size 11 20.81 mm 19.24 mm
Size 12 21.64 mm 20.05 mm

Now before you wonder how these numbers can help you, well this is where we hop to our next point which is about taking the measurement of your finger. But before we go somewhere like there I need you to understand this: these measurements are taken from the kit (thanks to ninjazzy from Reddit) itself but there is possibility that there would be variations between the kit productions. So be wary of it and make an informed decision.

Now where were we? Oh, yes we were about to measure the finger!

One Manual Way To Find Size For Oura Ring.

First thing first get yourself a rope. Or anything which can be tied around easily. Wrap it around your desired finger (one which you want to use for your Oura Ring). According to the Oura itself you are encouraged to use your index finger although there is no restrictions about it, you can use other fingers too.

Once you will have your – whatever you would’ve choose – all you need to do is wrap it around your finger and mark the point with marker where you think your ring should be. The next step is then all about using the scale and measuring that marked point from starting point, and that’s it. Doing this will make sure you get circumference of your finger. (We’ve the discussed the same method for Fitbits for small wrists)

Given all human fingers are circle (kind of) your next step is about doing math on your end. Circumference of circle is 2πr (r is the radius of the circle) and you need diameter so you will have to first find the radius by dividing the value you got with 2π after which all you will have to do is to multiply the value by 2 which will get you the diameter.

Which then will be used to compare the value with what we provided above in the table.

Or Get The 3D Printer To Print Oura Rings

I will not to pretend all high and mighty and act like 3D Printers are in everyone’s home. Because honestly even I don’t have one. But just because I don’t have one doesn’t mean you might not have one too. Because if you do then Oura provides the chance to download the 3D models of rings from their sizing kit and have them printed at your home.

As cool as it sounds since it can cost you we will not suggest that you make this your first option. Although, if you happen to be someone who can easily do it then we’ve added the link you need to download those files.

Keep in mind you should print rings on plastic and fine quality of plastic. Otherwise rough surfaces and scrawny texture might not be good enough.

Best Practices To Follow While Finding Oura Ring Size!

Now that we’ve talked about the Oura Ring sizing plan and how you can leverage it for yourself. This is perfect time to learn a bit more on what are the best practices that can aid you well. Starting with sensor bump Oura suggest that these should be at your palm side to ensure that your smart ring can provide results with accuracy. Besides this pattern ain’t something new, we’ve seen the same demands from Fitbit and Apple to for their wearables.

Another good practice that you can implement is to not settle for the ring where you feel there is gap. Or which renders a loose sensation on your finger. For the accurate results your Oura Ring should’ve good enough contact with your skin.

Which brings us to our next point and it is that you should always test the ring from kit for 24 hours. In one complete day a human finger contracts and expands many times which means you should’ve long enough sample of data to make the right decision.

Confirm Oura Ring Size At Website

Once you feel you have reached at the point where you are sure about your size, all you need to do is tell that to Oura through their website.

  • Visit ouraring.com/my-account

“I Still Can’t Find My Oura Ring Size!!!”

If you are anything like me only rings from the test kit will not help you too. In which case this is what you should know about: Always go for the small option between the two (notice how I said small not the smallest).

There are two reasons for it the first is that smaller your Oura Ring will be more effective would it be to give the insight since sensors needs to be in snug fit. This kind of orientation creates a firm bond between LED sensors and skin.

Another aspect is kit rings are made up of plastic which means they will stick to your finger more than an actual Oura Ring (they are made from Titanium to give them extra edge of durability) so to compensate for the difference of material it is both suggestable and recommended to go for the small option.

Oura Ring Sizing Plan: The End!

In the end making sure you choose the right size for yourself can be a stressful decision, but just because it can be a headache doesn’t mean it doesn’t deserve the wait. Because believe me Oura Ring are worth it. They are not only good enough to give you data about heart rate and SPO2 they are also incredibly water tolerant and can survive in the rough and tough conditions.
