What is a person hired to decorate the inside of a house called?

A person hired to decorate the inside of a house is called an interior decorator. Interior decorators help clients select and coordinate elements such as colors, fabrics, furniture, lighting, window treatments, wall coverings, and accessories.

The work focuses on the appearance, comfort, and furnishing of an interior. A decorator may create a color scheme, source furniture, arrange objects, recommend finishes, or supervise painting and installation. The goal is usually to shape the atmosphere and visual character of an existing space.

Interior decorator and interior designer are often used interchangeably in everyday conversation, but the professions can differ. Interior designers may also work with spatial planning, building systems, accessibility, and technical construction details. In some jurisdictions, the title “interior designer” is regulated, while “interior decorator” generally describes a broader decorating service rather than a legally protected professional designation.
