Hang artwork at the right height
Most people hang artwork too high. Place a piece so its bottom is only three to eight inches above furniture—lower for large pieces and slightly higher for small pieces. When there’s too much space between furniture and a painting, the eye rests on the void, blank wall between the two pieces.
Rearrange the bookshelves
Organize 60 percent of books vertically and 40 percent horizontally on the shelves. This creates balance yet spontaneity (and shows off the back of the bookshelf if it’s lined with a decorative fabric). Stack horizontal books lower than vertical ones: If the vertical books are 12 inches tall, place three to four books horizontally up to four inches high. Add green plants to soften the bookshelf, but avoid flowers, which can look cluttered and distracting.
Create space with the right mirror placement
Mirror, mirror, on the wall: What is the best placement of them all? Centered at about 57 inches high, experts say. This is an easy, strain-free eye level for most people. To create the illusion of more space, mount a mirror opposite a window to bounce light.
