The male and female wear the wedding ring on the same finger which is the ring finger (next to the pinky) of the left hand.
it used to be said that the ring finger had a vein that lead to the heart. :) <3
Right hand, ring finger.
On your ring finger, or the finger next to your little finger.
I suppose it depends where you're from.... traditionally, it's worn on the fourth finger of your left hand in some other countries and and cultures, it may be the same finger but on your right hand.
