Sizing and Fit
The Oura Ring 4 uses unique sizing that differs from standard US ring sizes. Achieving the correct fit is crucial for optimal performance and accuracy of the biometric tracking. It is highly recommended to size yourself with an Oura Ring 4 Sizing Kit before purchasing the ring.
Sizing Tips:
- Try on multiple sizes: Use the sizing kit to determine which size feels most comfortable across different fingers.
- Wear for 24 hours: Wear the sizing ring for a full day to assess comfort and fit under various conditions (e.g., swelling, temperature changes).
- Find your most comfortable fit: Select the size that provides a snug yet comfortable fit, ideally on your index finger for best performance and accuracy.
