Item Description

The Oura Ring 4 uses a custom sizing system that's different from standard ring sizes, so getting the right fit before you buy is important. This sizing kit lets you test the exact size you need without guessing. Sizes range from 4 to 15, with no half sizes available. You can wear your Oura Ring 4 on any finger, though the brand recommends your index, middle, or ring finger for the most accurate health tracking. The kit helps you determine which finger and size work best for your body. Wear the sizer for at least 24 hours to make sure it feels right for daily life. Your ring should sit securely at the base of your finger without rotating during normal activities. A properly fitted ring directly impacts how well it tracks your data and how comfortable it feels throughout the day and night. Since Oura Ring sizing doesn't follow traditional jewelry sizing conventions, testing beforehand eliminates the frustration of ordering the wrong size. When you purchase this sizing kit, you'll receive a 10 dollar credit toward your Oura Ring 4 purchase. This makes trying on sizes risk-free and gives you confidence before committing to the full ring. Whether you're a first-time Oura user or upgrading from an older model, getting the fit right from the start means better tracking accuracy and comfort from day one.
