What Sets Interior Designers Apart from Decorators

You might’ve heard the terms “interior designer” and “interior decorator” thrown around interchangeably, but the truth is, they’re two very different roles. Designers are the masterminds behind how spaces look and function, while decorators are the artistic stylists who add personality and flair. Here are ten differences between these two design pros to help you make the right call and understand who does what in the world of interiors.

Education Requirements

Many interior designers hold degrees in design, architecture, or similar fields, typically after years of study in design principles and structural concepts.

In contrast, decorators don’t necessarily have formal education, although some may take short courses in color theory or furniture selection. They rely on a natural flair for aesthetics and a good eye for what looks great together.

Role Scope

Think of interior designers as project managers for your space. They’re trained to handle structural changes, layouts, and even electrical plans if they’re designing rooms from scratch.

For decorators, the focus is on the final layer of decor—adding color, choosing furniture, and selecting accessories. They create the “look” of a room without changing its physical structure.

Collaboration With Contractors

Interior designers are used to working closely with contractors, electricians, plumbers, and even engineers. They often act as intermediaries between clients and tradespeople to ensure the project goes smoothly.

However, decorators have a different network of contacts, usually comprising furniture stores, art galleries, and decor suppliers rather than construction crews. Also, they might need to coordinate a few deliveries.

Technical Skills and Knowledge

A designer’s toolkit includes knowledge of building codes and ergonomic principles. They think about safety and accessibility—everything from the height of countertops to the width of hallways.

Meanwhile, decorators don’t typically need technical skills. Instead, they have an acute understanding of visual balance and color coordination. In short, they’re experts in creating harmony in a room.

Licensing and Certification

In many states, interior designers must pass an exam to become certified. Institutions such as the National Council for Interior Design Qualification ensure they know their stuff before letting them call themselves interior designers.

On the flip side, there’s generally no certification required to become a decorator, though some choose to become members of professional institutions like the American Society of Interior Designers.

Project Timing and Involvement

Designers are usually involved from the very beginning, often before construction starts. They take charge of creating the overall design concept.

When it comes to decorators, they usually step in at the end of a project once construction is finished and the walls are painted. Their job is to complete the look. Think of it this way: if designers set the stage, decorators bring the props.

Focus on Function vs. Flair

Functionality is prioritized by designers just as much as aesthetics, with layouts planned for optimal flow and rooms designed to suit daily life. Every inch is thoughtfully purposed.

For decorators, though, it is all about that final flair—their mission is to create an inviting, stylish atmosphere. They bring in the elements that catch the eye, like statement pieces and coordinated colors.

Skills in Space Planning

Using space efficiently is a skill, especially in tricky layouts. With CAD software, designers can reimagine a room’s proportions, making sure every inch counts.

While decorators also want the room to “flow,” they’re more concerned with the visual appeal rather than strict measurements. They’ll experiment with furniture placement for balance and ambiance.

Budget Management

Since designers work on larger-scale projects, they often manage extensive budgets. Plus, they need to track costs carefully, prioritizing both structural and aesthetic needs within the budget.

At the same time, decorators typically work with a smaller, set budget for decor items like furniture, art, and accessories. They’re all about helping you achieve a styled look within your means.

Client Approach and Consultation

During consultations, designers dig deep into how you’ll use each space, asking questions about routines, room usage, and personal habits to craft functional layouts.

In contrast, decorators keep things lighter—they’re more interested in your color preferences, favorite design styles, and decor desires. Their goal is to help you express your personality through design choices.
