Wear for 24 Hours

Your fingers naturally expand and shrink throughout the day due to temperature, activity, and sleep. To find your most accurate fit, wear the ring sizer for at least 24 hours, including during sleep.

A well-fitting ring should feel comfortable and stay securely in place without rotating during your daily activities.
