Look at the color and style of the rooms adjacent to the front hall. Note the dominant colors and the overall style of the art and accessories in those rooms.
Think about the impression you want to make on your guests when they enter the home. A sense of humor, love of antiques or a dramatic flair are some traits that will be defined by your decoration of the entry hall.
Measure the unobstructed portion of the wall in the front entryway. Exclude areas covered by furniture.
Search for artwork that matches the overall style, colors and personality of the adjacent rooms. For example, if the adjacent room features a beach theme with blue colors, a seashore print can be a nice incorporation.
Purchase one art print that is big enough to fill the majority of the available wall space, allowing for several inches on each side.
Order UV protective glass and a suitable frame for the artwork. The type of frame should reflect the style of art you have chosen. For example, a modernist print will use a simple black or white picture frame.
Hang the artwork at eye-level, centering it on the wall above any furniture present.
