Pictures should be grouped with furniture and wall to give an impression of unity.
Pictures should be hung as flat as possible.
Care is to be taken, that wires and nails used for hanging pictures are not visible.
The devices used like nails, hooks, wires for hanging should not show conspicuously.
Pictures should be hung at eye level of a standing person.
Small pictures should be grouped according to a common theme or color. While grouping, the picture, it is desirable to leave less space between the pictures than the picture themselves.
Lower edges of all the pictures in a room should be at the same level from the floor.
Pictures should not be hung in a step up fashion. This makes the arrangement more noticeable than the pictures. Odd numbers symmetrically arranged are more desirable.
Pictures should be so hung; that the center of interest comes is achieved at about the eye level. One should not first see the furniture in a room and then look up and see a line of pictures on the wall.
Most pictures are hung too high, and the eye is carried up toward the ceiling instead of being kept at the most interesting points in the room, which are at about the eye level of a standing person and below that point.
In successful picture arrangement the principle of emphasis plays an important part. If pictures are to be thoroughly enjoyed there must be plenty of plain space around them. Too much space, however, results in meagerness and inadequacy.
Pictures should be hung over a single piece or a group of pieces of furniture so as to become an integral part of the furnishing of a room, rather than appear to be isolated spots. When a picture is grouped with a piece of furniture, it is desirable to see the two as a unit. This may be accomplished by hanging the picture very near or by actually resting it upon the piece with which it is to group.
Rhythm, or consistent movement, must also be considered when arranging pictures and decorative objects. Pictures possessing line movement should be so placed that their lines carry the eye toward a group, and not away from it.
They should not be so hung that they carry the eye up toward the ceiling. If pictures to be grouped are similar in size they may be hung so that their centers will come on the same straight line. It is also correct to hang them so that their tops are on a straight line, and this is particularly successful in rooms having varied heights in the furniture. Another option is to create a straight line at the bottoms of the pictures, a plan that may well be chosen when a large object underneath them, such as a sofa or a long table, has a definitely straight line across the top
