I’ve come to realize that many people don’t properly hang their photos. It becomes especially apparent when I deliver and install a big print. When I look around houses I see that art on the wall is usually hanging too high. The standard height for museums is to have the center of the art 57 inches off the floor. If you closely look at galleries you’ll see they don’t think about getting the top or the bottom of art on the same line, they are concerned with the center. Now hanging in a home or office is a bit different, you don’t want to hang your photo so low it is partially hidden by a couch. But you want to keep that art behind the couch as low as possible, don’t have it a foot about the furniture.
