Interior Designer vs Decorator: What Is the Real Difference?
Not sure whether you need an interior designer or a decorator? Here is a clear breakdown of what each one does, how they are trained, what they cost, and how to choose the right pro for your project.
The terms “interior designer” and “interior decorator” get used interchangeably all the time, but they describe two different jobs. One deals with how a space works. The other deals with how it looks. Knowing the difference can save you from hiring the wrong professional, or paying for expertise you do not actually need.
In short: an interior designer is trained to shape the structure and function of a space, often working alongside architects and contractors. An interior decorator focuses on the finished look, choosing furniture, color, fabric and accessories for a space that already works. Here is how the two compare, project by project.

What an Interior Designer Does
Training and scope
Interior designers typically complete formal education in design, covering space planning, building codes, materials and sometimes structural basics. Many pursue professional certification. Because of this training, designers can work on projects that involve moving walls, reworking a floor plan, or coordinating electrical and plumbing changes alongside architects and contractors.
What they handle
- Space planning: Deciding how a room or home should be laid out for the way you actually live.
- Structural input: Working with architects or contractors on walls, windows and layout changes.
- Materials and finishes: Selecting flooring, countertops, cabinetry and fixtures.
- Project management: Coordinating contractors, timelines and budgets on renovations.
- Aesthetics: Many designers also handle furniture and decor, blending function with style.
Hire a designer if…
- You are renovating, building new, or changing a floor plan.
- Your project involves structural, electrical or plumbing changes.
- You want one professional managing both function and look.
What an Interior Decorator Does
Training and scope
Interior decorators do not need formal education or licensing, though many take design courses or build a portfolio through hands-on work. Their focus stays on the visual layer of a space rather than its structure. A decorator works within the walls, windows and layout you already have.
What they handle
- Furniture selection: Choosing and arranging sofas, tables, chairs and storage.
- Color and fabric: Paint colors, upholstery, drapery and rugs.
- Accessories: Art, lighting, mirrors and decorative objects that pull a room together.
- Styling: Arranging existing pieces alongside new ones for a finished, cohesive look.
- Refreshes and staging: Updating a room’s look or preparing a home to sell, without construction.
Hire a decorator if…
- Your layout and structure already work, and you want a new look.
- You need help choosing furniture, color or fabric.
- You are staging a home for sale or refreshing a room on a shorter timeline.
Matching the Professional to the Project
| Project type | Best fit | Why |
| Kitchen or bathroom remodel | Interior designer | Involves plumbing, electrical and layout decisions |
| New home build | Interior designer | Requires coordination with architects and structural planning |
| Living room furniture refresh | Interior decorator | Works within the existing layout on furniture and styling |
| Home staging for sale | Interior decorator | Focused on visual appeal, not structural change |
| Open-concept conversion | Interior designer | Requires wall removal and structural expertise |
| Color and decor update | Interior decorator | Purely aesthetic, no layout changes needed |
Cost Comparison
Fees vary widely by location, experience and project scope, but the general cost structures below hold true across most markets.
| Fee structure | Interior Designer | Interior Decorator |
| Hourly rate | Often higher, reflecting technical training and project management | Typically lower, focused on styling time |
| Flat project fee | Common for renovations; scales with project complexity | Common for a room refresh or full-home styling package |
| Percentage of project cost | Sometimes used on larger renovations (a percentage of construction or furnishing spend) | Less common; more typical on large furnishing budgets |
| What drives the cost | Scope of structural work, permits, coordination with contractors | Number of rooms, furniture budget, sourcing time |
Tip: Ask any professional, designer or decorator, for a written estimate or fee structure before work begins, and clarify whether furniture and materials are billed separately from their fee.
Questions to Ask Before Hiring Either Professional
- Can I see a portfolio of projects similar to mine?
- How do you charge, and what is included in that fee?
- Who selects and purchases furniture, materials or finishes, and is there a markup?
- What is the expected timeline for a project like mine?
- Do you carry insurance, and do you hold any relevant certification?
Frequently Asked Questions
What is the main difference between an interior designer and a decorator?
An interior designer handles the function and structure of a space, often working with architects and contractors, while a decorator focuses on the look of a space that already works, such as furniture, color and styling.
Do interior decorators need a license?
No. Decorating is not a licensed profession in most places, while some interior design work, especially involving structural changes, may require certification or licensing depending on location.
Is an interior designer more expensive than a decorator?
Often, yes, because designers bring more technical training and may manage contractors and construction. Costs still vary widely based on project scope and location.
Can one person do both jobs?
Yes. Many interior designers also handle decorating tasks like furniture and styling, so a single professional can sometimes cover the full project.
Do I need a designer for a small room refresh?
Usually not. If you are just updating furniture, paint and decor without changing the layout, a decorator is typically enough.
Who do I hire for a kitchen remodel?
An interior designer, since kitchen remodels usually involve layout changes, plumbing and electrical work that a decorator is not trained to handle.
Final Verdict
If your project involves changing a layout, moving walls, or coordinating with contractors, an interior designer is the right call. If your space already works and you just want it to look better, an interior decorator can get you there, often faster and for less.
Some projects call for both: a designer to shape the bones of the space, and a decorator to bring in the finishing touches. Either way, matching the professional to the actual scope of your project is the surest way to get a result you love without overpaying for expertise you did not need.
