The position of address plaque is not just about the way they look, but it is also about making it useful. The first factor to consider is the visibility of the house number. Ideally, this must take precedence over everything else. Then comes the style aspect. Try to make it symmetrical if you can. Align the plaque such that it complements the architectural features of your home. Unless you have no other options, it is always better to place the house number on the front door. Also, hang it such that the number is at the eye level for the average person.
