What Is a Ring Size?
Ring size is a number that corresponds to the inner measurement of a ring. In the United States, sizes typically range from 3 to 13 in quarter-size increments.
A well-fitting ring should feel snug yet comfortable. It should slide over the knuckle with a bit of resistance and sit securely at the base of the finger without feeling tight. The goal is a fit that feels natural and stays in place during daily activities without constriction.
