The May issue of House Beautiful magazine has a 4 page spread of 101 Designer Secrets. We read them and decided to share along with some commentary. Not all 101 will be shared, but you can click on the link above to HB, or subscribe to their hard copy magazine to read them all if you wish to.
SECRET #4:
The hang up–where to hang my artwork? I’ve found that 63″ on center above the floor is a perfect viewing height for most pieces-Hunter Kaiser
Commentary by S Interior Design–
It is definitely one of the most common faux pas —hanging the artwork too high on a wall. If the person doing the hanging is 6′-3″ their perspective is different from someone who is 5′-5″. This is a good rule of thumb to begin with, 63″ above the floor. Variables to consider include whether the art is above a piece of furniture and the height of that furniture.
When the art is not being hung above a piece of furniture, the guideline changes. I like to ‘own the wall visually’ if that is the only element being placed. Then lower placement and stacked art work higher on the wall often makes more sense.

SECRET #5
When you are hanging a series of pictures together, keep the gap between them 2 to 2 1/2″ to really utilized the wall space, and keep a minimum of 9″ between the art and the tops of sofas and chairs-Milly De Cabrol
Commentary by S Interior Design-
Agree and then a small disagree. Yes to the gap between pieces of art being hung together, but we generally keep the space between the art and tops of sofas and chairs to 7″. Again, style of the furniture, height of the ceiling and the composition of the art being hung are variables to be considered.
Summary-
There are good rules of thumb but all situations should be evaluated as unique to determine the best way to hang and display your artwork.
