In the United States, women usually wear their wedding rings on their left hands. This varies by area and culture — for example, in part of Europe, the wedding ring is worn on the right hand.
Most modern cultures do agree that the wedding ring is worn on what has come to be known as the ring finger, the third finger not counting the thumb. This is largely believed to be because ancient cultures believed that the third finger's vein went directly to the heart, and the tradition has been passed on through the years.
