Oura Ring 5 Sizing Kit

The Oura Ring 5 Sizing Kit helps you find the perfect fit before purchasing, allowing you and others to determine the right ring size.

Size Before You Buy

Oura Ring 5 sizes differ from standard ring sizes. Use the Oura Ring 5 Sizing Kit to find your correct size before ordering.

Not Standard Sizing

Oura Ring 5 sizes differ slightly from standard ring sizes and other Oura Ring models. Available in sizes 6–13, with no half sizes.

Comfort and Accuracy

A properly fitting Oura Ring 5 helps ensure optimal data accuracy, comfort, and overall experience.

Choose a Finger

Oura Ring 5 can be worn on any finger and either hand. For optimal accuracy, the index, middle, or ring finger is recommended. Make sure to size the exact finger you plan to wear it on.

How It Should Fit

Oura Ring 5 should fit securely and comfortably at the base of your finger without rotating easily.

Wear Test

Fingers expand and contract due to environmental factors. Wear the ring sizer for 24 hours to confirm the best fit. It should remain secure during normal daily activities.

Materials

The sizing rings are made of plastic, while Oura Ring 5 is crafted from durable, scratch-resistant titanium for comfort. The plastic sizing rings may feel less comfortable than the actual ring due to the material and molding process.
