The terms interior designer and interior decorator are related and often used interchangeably, but they have distinct differences.
An Interior designer focuses on creating a functional and aesthetically pleasing space by designing the layout, considering elements such as lighting, acoustics, and the overall functionality of the space, selecting fixtures and accessories and choosing colors, materials, and finishes.
On the other hand, an interior decorator focuses on the style and appearance of a room, including the choice of artwork, rugs, curtains, and other accessories that complement the design.
Interior designers often collaborate with interior decorators to help choose appropriate furnishings and decorative elements that align with the overall design concept.
While there is some overlap between interior design and interior decoration services, they are fundamentally different disciplines that require different qualifications and expertise. If youโre looking to make changes to your living space, itโs important to understand what interior design is and what interior decorators do so you can find the right person for the job.

What is interior design?
The International Interior Design Association (IIDA) defines Interior design as the art and science of improving the interior of a building or space with the goal of creating a more functional and visually appealing environment.
It involves understanding and fulfilling a space’s functional and aesthetic requirements of a space by selecting and arranging decorative elements such as color, lighting, furniture, fabrics, and accessories.
Interior design also considers aspects such as traffic flow, spatial planning, acoustics, and sustainability. It can be applied to various types of spaces, including residential homes, offices, retail stores, hotels, and public buildings.
What is the purpose of interior design?
The purpose of interior design is to transform ordinary homes into something extraordinary by creating a living space that is both aesthetically pleasing and functional. Interior designers work hard to combine form and function so that residents can live in comfort, security, and beauty. They balance colors, textures, furniture pieces, window treatments, lighting fixtures, and more to give their clients the perfect home.
Interior design is about creating a space that is both enjoyable and practical to live in. That means considering the layout of a room, the design of furniture pieces, the materials used for flooring, wall coverings, and window treatments, as well as considering how people use a space and how they move around it.
What does an interior designer do?
An interior designer is a professional who can help transform your space into a beautiful, livable area that reflects your personal style.
Interior designers are also knowledgeable about architectural elements such as space planning and structural considerations. They will consider how much natural light comes in and what kind of flooring you have before deciding which pieces will work best in the room. Their expertise can help bring your vision to life with bespoke touches that make your home feel comfortable yet chic.
They work with clients to create a design plan that meets their functional and aesthetic requirements, including selecting and arranging furniture, choosing colors and materials, and designing lighting and other key elements of the space. They may also collaborate with other professionals, such as architects, contractors, and engineers, to ensure the design is implemented correctly and safely.
Architect vs. Interior Designer: Who Should You Hire?
One of the key differences between an architect and an interior designer is that architects focus on the design and construction of buildings. In contrast, interior designers focus on the interior spaces within those buildings.
Depending on the scope of your project, you may benefit from hiring one or both of these professionals. For instance, if you’re building a new home or making significant structural changes to your current space, you’ll likely need the services of an architect.
On the other hand, if you’re simply looking to refresh your interiors with new furnishings, lighting, and decor, an interior designer may be the better choice. Ultimately, the decision of who to hire will depend on your project’s specific goals and requirements.
Required Credentials for Interior Designers
To become an interior designer in the United States, one must pass an exam and register with a governing council such as the American Society of Interior Designers (ASID). ASID is the oldest and largest professional organization for interior designers, suppliers, and manufacturers.
So if you are looking to hire the services of an interior designer, make sure you look for someone with qualifications from a governing body like ASID.
Interior design requires extensive and systematic training, formal education, and a great eye for aesthetics. A talented interior designer must have experience in space architecture and be able to look at different surface finishes with artistic flair.
