Here's a typical example. Couch and pictures tall enough to be eye-level with an NBA star or a giraffe. It might remind you of visiting your hubby's house (the bachelor pad) when you were dating. The walls, if it had art, were hung with 8x10 frames spaced too far apart high enough to cause a nose-bleed if you were to ever see it eye to eye.
So what's the rule? Museums typically hang their art 54 inches to the center of the artwork or grouping. This is prime viewing, even if you're in the NBA. It also happens to be a good decorating rule of thumb.
A simple change in picture height and arrangement can change and entire room! Take it from a 64 inch woman who's 54 inches off center tonight.... hanging pictures 54 inches TO center makes the room balanced and well arranged.

Off to bed. I'm going to paint the other direction tomorrow to even out my obvious resemblance to the leaning Tower of Pisa.
