Which Size Oura Ring Should I Buy? – Our Guide

Oura rings are an investment for people who are into health tech, meaning it’s important to choose the right size if you want to avoid losing your money or having to send your Oura ring back.

Oura rings are said to be true to size thanks to their sizing kit, you can switch them between different fingers until they fit right with desired snugness.

Down below, we’ve put together an extensive sizing guide below, taking you through how to choose your ring size, factors to consider and some tips.

How To Choose Your Oura Ring Size?

Choosing the right size for your Oura ring is very important, the correct ring size will ensure that your ring is comfortable to wear and give the highest data accuracy with the best usage results.

This is why Oura give a sizing kit before you order according to your finger size, this sizing kit comes with plastic ring sizers ranging in sizes between 6-13.

When you get your sizing kit rings, follow the steps below in order to choose the right-sized ring.

  • Step one – Start by opening your sizing kit and choosing the usual ring sizes for your hand, note that all of the sizing kit rings have the same width and circumference, they might seem slightly different in weight however and are more uncomfortable to wear than the actual ring.
  • Step two – Now choose your finger, avoid the fingers with larger knuckles and instead opt for the ring finger, middle finger or index finger.
  • Step three – Make sure you have the proper ring orientation, the sensor bumps should always be on the palm size of the finger so that the ring can be able to track your health data properly and make sure the ring fits snug but not too tight.
  • Step four – Fingers can contact and expand due to the environment, therefore we suggest testing the typical ring size for your finger for at least 24 hours in total, the ring should stay in the same place during the day.
  • Step five – Now confirm your ideal ring size on the website and place your order!

Factors To Consider When Choosing An Oura Ring Size

If you’ve come across two sizes which fit well during the sizing process you might be stuck between the two.

Consider these two factors to help you decide, but in most cases, you should size down.

  • Accuracy – In order for the Oura ring to work properly, the sensor bump and LED sensors need to be snug on your skin but not uncomfortably tight, in this case, choose the ring which fits more tightly.
  • Materials – Plastic ring sizers can feel stickier on your skin, the actual Oura ring however will not slide around during daily wear due to the mould, therefore choose the ring size which feels more comfortable.

Which Fingers Should I Wear My Oura Ring On?

One of the great things about the Oura ring is that you can wear them on any finger as long as the sensor bump is against the skin properly.

It is recommended to wear the Oura ring on the index, ring or middle finger, other fingers such as the thumb finger and pinky finger can be uncomfortable, we also suggest not wearing your Oura ring next to another ring finger which can cause friction.
