Principles Of Interior Design by Kathy Iven
Whether you are working with existing furnishings and fabrics or “starting from scratch” with an empty room, you should always use the elements and principles of design as a guide in choosing everything. The elements are your tools or raw materials, much like paints are the basics to a painter. The elements of design include space, line, form, color, and texture. The principles of design relate to how you use these elements. The principles of design are balance, emphasis, rhythm, proportion and scale, and harmony and unity.
Principle #1: Balance Visual equilibrium in a room is called balance. It gives a sense of repose and a feeling of completion. A well-balanced room gives careful consideration to the placement of objects according to their visual weight. The elements of line, form, color and texture all help determine an object’s visual weight, which is the amount of space it appears to occupy. Balance also refers to how and where you place the elements (line, form, color and texture) within a room. To maintain balance, try to distribute the elements throughout the room.
- Formal balance, often referred to as symmetrical balance, creates a mirror image effect.
- Informal balance uses different objects of the same visual weight to create equilibrium in a room. It is more subtle and spontaneous and gives a warmer, more casual feeling.
Principle #2: Emphasis Emphasis is the focal point of the room. The focal point should be obvious as you enter the room; it is the area to which your eye is attracted. Whatever is featured, as the center of interest –a fireplace, artwork or a window treatment framing a beautiful view – must be sufficiently emphasized so that everything else leads the eye toward the featured area. You can add emphasis to a natural focal point or create one in a room through effective use of line, form, color and texture.

Element #1: Space
Space defines the boundaries and sets the limits on the functional and decorative things you can do. Usually you will not determine the space; instead, you will be faced with the challenge of using the existing space effectively.
Element #2: Line
The lines in a room are second only to color in importance when it comes to setting the overall mood or feeling of a room. The lines of window fashions should support the dominant line of the room. In most situations, the dominant line is straight (vertical, horizontal or diagonal) rather than curved. Your choice of emphasizing the direction of lines will determine the mood you want to create.
- Vertical lines add height and dignity, creating a more formal atmosphere. Vertical lines also balance the horizontal lines found in most furniture.
- Horizontal lines tend to create a restful, informal feeling. They work well in casual rooms or as relief to the strong verticals of formal rooms.
- Diagonal lines attract attention and lead the eye. They can be disturbing unless supported by verticals or opposing diagonals.
- Curved lines add a softening effect and keep the room from becoming too stiff. Use curved lines with some restraint to keep the room from becoming too soft and overly feminine.
