Oura Ring 5 Sizing Kit

The Oura Ring 5 Sizing Kit allows for you and those around you to find the ideal fit before purchasing. A properly fitting Oura Ring 5 will result in the highest possible data accuracy, comfort, and overall experience.

• Oura Ring 5 sizes are slightly different from standard ring sizes and other Oura Ring generations. It's important to size yourself and follow sizing instructions.
• Oura Ring 5 works on all fingers and can be worn on either hand. For optimal accuracy, we recommend wearing on your index, middle, or ring finger.
• Size the exact finger you plan to wear your Oura Ring 5 on.
• Oura Ring 5 should fit securely and comfortably at the base of your finger. Your ring should not rotate easily.
• Your fingers expand and contract based on environmental factors, so we recommend wearing your ring sizer for 24 hours to confirm your best fit.
• Our sizing rings are made of plastic, while the Oura Ring 5 is crafted in durable, scratch-resistant titanium for comfort.
• This sizing kit is only compatible with Oura Ring 5.
