Introduction
The Oura Ring 4 Sizing Kit is designed to help you find the most accurate and comfortable fit for your Oura Ring 4. Achieving a proper fit is crucial for ensuring the highest possible data accuracy, comfort, and overall experience with your Oura Ring. This kit is specifically for the Oura Ring 4 and is not compatible with Oura Ring Gen3 or earlier models.
The kit contains a series of plastic sizing rings, each marked with a unique Oura size. These sizes are specific to Oura Rings and do not correspond to standard US or international ring sizes.
Setup
Unboxing the Sizing Kit
Upon receiving your Oura Ring 4 Sizing Kit, carefully open the packaging. You will find a tray containing multiple plastic rings, each labeled with a size number.

Understanding Oura Sizes
Oura Ring sizes are unique. Do not compare them to your existing jewelry ring sizes. The goal is to find a size that feels secure but not too tight, allowing for slight movement without rotating freely.
Operating (Sizing Process)
Follow these steps to determine your optimal Oura Ring 4 size:
- Try on Multiple Sizes: Begin by trying on several sizing rings from the kit. Focus on your index finger, as this is the recommended finger for best performance and accuracy of the Oura Ring. However, you may also try other fingers if preferred.
- Assess the Fit: The sizing ring should fit snugly but comfortably. It should be easy to put on and take off, but not so loose that it spins freely on your finger. Ensure it can pass over your knuckle without excessive force.
- Wear for 24 Hours: Once you find a size that feels promising, wear that specific sizing ring for at least 24 hours. This allows your finger to experience natural swelling and shrinking throughout the day and night, ensuring the chosen size remains comfortable and accurate in various conditions.
- Find Your Most Comfortable Fit: After 24 hours, re-evaluate the fit. The ideal size will feel comfortable and secure, allowing for consistent sensor contact without being restrictive.

Important Note: For best performance and accuracy, we recommend wearing your Oura Ring on your index finger.

Maintenance
Cleaning the Sizing Rings
The plastic sizing rings can be cleaned with a soft cloth and mild soap and water. Rinse thoroughly and air dry. Avoid harsh chemicals or abrasive materials that could damage the plastic.
Storage
Store the Oura Ring 4 Sizing Kit in its original packaging or a clean, dry place away from direct sunlight and extreme temperatures to prevent deformation or damage.
Troubleshooting
No Size Feels Right
- If you are between two sizes, consider which finger you intend to wear the Oura Ring on. Often, a slightly looser fit is preferred for comfort over extended periods, but ensure it's not so loose that it rotates freely.
- Try wearing the sizing rings on different fingers (index, middle, or ring finger) on both hands, as finger sizes can vary.
- Ensure you are wearing the sizing ring for a full 24 hours to account for natural fluctuations in finger size.
Sizing Ring Feels Too Tight or Too Loose
- If it feels too tight, try the next size up.
- If it feels too loose, try the next size down.
- Remember, the ring should be snug enough to maintain consistent contact with your skin for accurate sensor readings, but not so tight that it causes discomfort or restricts circulation.
