I'm comparing it to my previous wallet which had room for an extra card on each side and we're talking an extra 3/8 inch in height and width and the leather is a bit thicker. Not much, but I have a lot in my pocket. Slightly thicker for the same number of cards. In the attached photo on the left is a new wallet, on the right is my old one.
