Many designers are guided by what is known as the "golden ratio." This mathematical ratio describes the ideal proportions of a room or building in terms of approximately 60/40. Throughout history, many designers, painters and architects have used this principle, including those who built the Taj Mahal and the Parthenon. In the field of interior design, the golden ratio principle can relate to the placement of objects or influence the use of color in the room's palette:

  • 60 percent neutral colors
  • 30 percent darker furniture
  • 10 percent warmer colors including 5 percent bright accents and a touch of cooler tones.

The room's dimensions determine the size and shape of furniture, window coverings and accent pieces so that the room's design remains in proportion. Interior designers use the basic dimensions and shape of a room to create focal points and lines of vision.

Geometric elements themselves come in and out of fashion periodically in terms of furnishings and patterns for textiles and housewares. Strong geometric elements and repetitive patterns are thought to have a calming effect.
