Oura Ring 5 Sizing Kit

Find your perfect fit before ordering your Oura Ring 5.

The Oura Ring 5 Sizing Kit helps you determine the ideal size for the best comfort, accuracy, and overall experience. Since Oura Ring 5 sizes differ from standard ring sizes and previous Oura generations, we strongly recommend sizing yourself before making your purchase.

Once you've found your size, you can order your Oura Ring 5 with confidence. The cost of the sizing kit will be automatically deducted from your Oura Ring 5 purchase at checkout.

Oura Ring 5 can be worn on any finger and on either hand. For optimal accuracy, we recommend wearing it on your index, middle, or ring finger. Simply follow the sizing instructions included in the kit to find your best fit.
