The Oura Ring 4 Sizing Kit helps you find the right fit before you buy your Oura Ring 4. Oura Ring 4 sizes are different from standard ring sizes, so using this kit ensures you choose the correct size from 4 to 15. There are no half sizes, so getting the size right matters.

The sizing rings are made of plastic, so they may feel less comfortable than the actual titanium Oura Ring 4. The kit lets you try different sizes on the exact finger you plan to wear your ring on, so you can find a secure and comfortable fit that supports accurate data and everyday comfort.

How to Use

Use the sizing kit to try different sizes on the exact finger you plan to wear your Oura Ring 4 on. Wear the sizer for at least 24 hours to confirm your best fit. The ring should fit securely and comfortably at the base of your finger and should not rotate during normal daily tasks.

Tip: For optimal accuracy, Oura recommends wearing your Oura Ring 4 on your index, middle, or ring finger. Size the exact finger you plan to wear it on.
