You may have occasionally heard the terms for interior decorator and interior designer interchanged. However, there is a difference between the two titles. An interior decorator generally refers to someone who deals with finishes, surfaces, furniture, and wall coverings. Also, an interior decorator may work in a variety of venues from a design showroom to a remodeling retail store.
An interior designer is a more specialized career field, requiring a certain combined level of education, work experience, and licensing. An interior designer may create spaces for the inside of a commercial office building, design the lighting for a restaurant, or select the furnishings of a home. An interior designer may also deal with issues of safety like accessibility and building codes.
