The Oura Experience
Sizing
A properly fitting Oura Ring will ensure the highest possible data accuracy, comfort, and overall experience.
- Use the Oura Sizing Kit: Oura uses whole sizes only (no half sizes), and they differ slightly from standard US ring sizes
- Choose your finger: Try sizers on both hands and different fingers to find the most comfortable fit. The index finger is recommended for best accuracy
- Test for comfort: The ring should feel snug but not tight
- Wear for at least 24 hours: Wear the sizer throughout the day and night (including sleeping) to account for natural changes in finger size
- Between sizes? Choose the smaller size to help keep sensors in close contact with your finger
