What Is a Ring Size?
Ring size is a number that reflects the inner measurement of a ring. A perfect fit should feel snug yet comfy, sliding over your knuckle with a gentle resistance and resting securely at the base of your finger. The aim is for a natural fit that stays put during your daily activities without feeling tight.
