While the terms 'interior designer' and 'interior decorator' are often used interchangeably, they represent distinct professions with some overlapping work. The primary difference lies in the scope of their projects.
An interior decorator focuses on the aesthetics of a space, making less permanent decisions about decor. Their work involves selecting colors, fabrics, furniture, wall art, paint, and other finishes to 'dress' a room and enhance its style.
An interior designer has a broader scope that includes a decorator's aesthetic focus but also extends to the structural and functional aspects of a space. Designers are qualified to plan layouts, make structural changes, and manage overall functionality. They handle permanent decisions regarding fixtures like cabinets and bathtubs, establish floor plans, and may hire contractors.
Due to the technical skills required, interior designers typically have formal education, certification, and may hold a license, which can result in higher fees. As a general rule, it is best to hire an interior designer for major remodeling projects and an interior decorator for projects focused on establishing or refreshing a home's interior style.
