Individuals can decorate walls with art by hanging a picture or a group of pictures so that the center point is at the average person's eye level, says About.com. It's best to select art that highlights the wall space and dimensions of nearby furniture.
When hanging several pictures in one space, the group should be considered as a single unit, notes About.com. Laying the pictures out on the floor or on a large table and trying various combinations before hanging is a good strategy. Large pictures complement wide walls, and small pictures complement narrow walls. Other considerations to keep in mind include balance, line and symmetry.
