Interior design and interior decorating are often mistaken as the same thing, but the terms are not completely interchangeable. There are many similarities between the two jobs—so many, in fact, that opinions vary on exactly where to draw the distinction. There are also more than a few differences between the professions—some subtle, some significant. As you decide which kind of help you need when planning changes in your home, it will help to understand the differences between professional designers and decorators—their schooling, the credentialing, their services, and their clientele.

Interior Design

Schooling: Interior design is a profession that requires specific schooling and formal training. The work involved usually includes studying color and fabric, computer-aided design (CAD) training, drawing, space planning, furniture design, architecture, and more. Upon graduating, designers often apprentice with a registered and established interior designer before moving on to establish their own companies.

Credentials: In some states and provinces, professional designers are required to pass an exam and become registered with a governing council (which one will depend on what country and state/province he or she is in) before they can be called designers. However, there are just as many locations where no credentialing is required. So it's a good idea to find out what the situation is in your area before starting your search.

What they do: Designers are comfortable with spatial planning and can help design and renovate interiors—from drawing up the initial floor plans to placing the last decorative accent. Designers don't just enhance the look; they also enhance the function of a room.

Who they work with: Interior designers often work closely with architects and contractors to help achieve the look the client desires, whether that client is designing a residential home, an office, a hotel, or any other interior space.
