If you're planning a project, you've probably noticed that "interior designer" and "interior decorator" get used as if they mean the same thing. They don't, and hiring the wrong one is one of the more expensive mistakes a homeowner can make. Not because either is better, but because they solve different problems.
The short version: a decorator works on the surface of a space. A designer works on the space itself, and then on the surface too. Here's what that means in practice.
What an interior decorator does
A decorator furnishes and styles rooms that already exist. They work with the walls, windows, and floor plan you have, and focus on what goes inside: furniture, rugs, window treatments, lighting, art, color, and accessories.
A good decorator has a strong eye for color, scale, and balance, and knows where to source pieces that suit your taste and budget. If your home is structurally sound and laid out the way you like, a decorator can transform how it looks and feels without touching a single wall.
What an interior designer does
A designer does everything a decorator does and also works on the structure and function of the space. (For the full walkthrough, see what an interior designer does.) That includes:
Space planning. Deciding how a room or an entire floor is organized: where walls go, how traffic flows, where the kitchen island sits, how a primary suite connects to its bath and closet.
Drawings and specifications. Producing the floor plans, elevations, lighting plans, and material specifications that contractors build from. On a renovation, these documents are the project.
Construction coordination. Working with architects, general contractors, and trades during the build, answering questions, solving problems on site, and making sure what gets built matches what was designed.
Custom work. Designing millwork, cabinetry, built-ins, and details that don't exist in a catalog. See our residential design service for how this works across a whole home.
Then comes the part a decorator also does: furniture, finishes, color, and styling, now chosen in the context of a layout the designer planned from the start.
Residential Design
Interior designer vs. decorator at a glance
Focus. A decorator focuses on appearance: furnishings, color, and styling. A designer focuses on both function and appearance: layout, structure, and finishes.
Construction involvement. A decorator typically has none. A designer is involved in renovations and new builds, and works with contractors and architects.
Deliverables. A decorator produces mood boards, furniture selections, and a styled room. A designer produces all of that plus plans, elevations, specifications, and a coordinated build.
Best for. A decorator suits a refresh of rooms you already like the bones of. A designer suits renovations, new construction, and any project where the layout needs to change.
One note on titles: "interior designer" and "interior decorator" are both used loosely, and neither is a license to build. Structural work still requires an architect or engineer and a licensed contractor. What matters when you hire is the scope of work the person has actually done, so ask to see completed projects like yours.
Which one do you need?
A simple way to decide is to ask whether anything is changing besides what's in the rooms.
You probably need a decorator if your layout works, your finishes are staying, and you want help furnishing, styling, and pulling a space together. A single room refresh or a furnished-and-staged home often falls here. Our interior styling and furniture sourcing services are built for this kind of project.
You need a designer if you're renovating a kitchen or bathroom, moving or removing walls, building an addition or ADU, building a new home, or redoing the floor plan in any way. These projects involve drawings, permits, and contractors, and the decisions interact: the lighting plan depends on the ceiling, the cabinetry depends on the plumbing, and the furniture depends on the layout.
The problem we see most often is a homeowner who starts a renovation with a decorator, then discovers at the contractor stage that nobody has drawn the plans. Fixing that midway costs time and money. When in doubt, start with a design consultation: design consulting is a low-commitment way to find out which kind of help your project needs before you commit to a full engagement.
How fees compare
Designers generally charge more than decorators, because the scope is larger and includes planning, drawings, and project management. But the fee alone isn't the right comparison. A decorator is the lower-cost option for a project that is genuinely decorating-only. For a renovation, hiring a decorator and discovering you also needed a designer usually costs more than hiring the designer first.

Common questions
Is an interior designer the same as an interior decorator? No. Decorators focus on the look of a finished space. Designers do that and also handle space planning, drawings, and construction coordination.
Can an interior designer also decorate? Yes. Decorating is part of interior design, and most designers handle everything from layout through final styling.
Do I need an interior designer or a decorator? If your walls and floor plan are staying as they are, a decorator may be enough. If you're renovating, building, or changing the layout, you need a designer.
Which costs more? A designer, usually, because the scope is wider. But the right choice depends on the project, not the fee: the cheapest option is the one that gets the job done once.
