A ring that fits well will comfortably glide over your knuckles and be slightly tight around your finger. According to Jogia, there should be some friction putting the ring on and taking it off. If it easily comes off by moving your fingers, it's too loose. A representative at Mociun believes the ring should not spin around your finger: "a good fit will ensure a stone doesn't slide to the side or back of your finger."
Yoon suggests avoiding what she calls a muffin top. "You want to avoid the ring pinching you in any way, causing a muffin top: where the ring is a little too snug so that it looks uncomfortable." Overton said rings should not cause pain or require water or soap to remove. "A really great test for this is that another person should not be able to remove your ring from your finger with ease."
If you notice you have a more pronounced knuckle in the middle of your finger, make sure you communicate that with the jeweler when sharing your ring size. Chances are the jeweler will go up or down by a quarter size, creating a better fit for you. Overton also reminded us: "A wider band size means more metal, which will affect how the ring fits. Any band that's roughly 4 mm and up might need to be sized up by a half to full size to accommodate movement and the extra metal on your finger."
