What is the difference between an interior designer and an interior decorator?

Interior designers are professionally trained in space planning. In 18 states, they must pass a strict exam and be licensed by the National Council for Interior Design Qualification (NCIDQ). Although Colorado is not yet legislated, look for qualified designers who have chosen to take the NCIDQ test.  While both designers and decorators are concerned with aesthetics, style and mood, interior designers have comprehensive training and command skills that may include an understanding of:
  • flame spread ratings, smoke, toxicity and fire rating classifications and materials for commercial spaces
  • space planning for public and private facilities
  • national, state and local building codes
  • standards regarding the needs of disabled or elderly persons and other special needs groups
  • ergonomics
  • lighting quality and quantity
  • acoustics and sound transmission
A decorator works only with surface decoration - paint, fabric, furnishings, lighting and other materials. Because no license is required, upholsterers, housepainters, and other tradespeople also claim the name "decorator."
