Interior Design vs. Interior Decorating: Know the Difference

If you’ve ever wondered whether you need an interior designer or an interior decorator, you’re not alone. These terms are often used interchangeably — even by professionals — but they actually refer to two distinct services.

Understanding the difference can help you choose the right expert for your project, avoid miscommunication, and get the most value for your investment.

Let’s break it down.

What Does an Interior Designer Do?

Interior designers are trained professionals who work with both the function and the form of a space. Their work typically begins before the space is even built — or during major renovations — and often involves collaboration with architects, builders, and contractors.

Key responsibilities include:

• Space planning and layout optimization

• Structural changes (like moving walls or modifying floorplans)

• Selecting materials like flooring, tile, countertops, and cabinetry

• Ensuring the space meets building codes and safety regulations

• Designing for accessibility, ergonomics, and daily functionality

Designers often hold formal education in interior design or architecture and are knowledgeable in construction practices, lighting design, and building systems.

Think of interior design as a blend of science, strategy, and creativity — all working together to shape how a space functions and feels.

What Does an Interior Decorator Do?

Interior decorators, on the other hand, come in after the structural work is done. Their focus is on aesthetics — the finishing touches that make a house feel like a home.

Decorators help with:

• Selecting furniture, rugs, lighting, and window treatments

• Choosing paint colors and wallpaper

• Styling shelves and coffee tables

• Creating mood boards and visual inspiration

• Layering textures and patterns to create a cohesive look

Decorators may or may not have formal design training, but they have a keen eye for color, composition, and balance. Their goal is to make a space beautiful, personalized, and emotionally resonant.

Which One Do You Need?

The answer depends on the scope of your project:

• Building or renovating? You likely need an interior designer to help with layout, materials, and functionality.

• Want to refresh a room with new furniture or decor? An interior decorator is a great fit.

• Not sure? Many professionals (ourselves included!) offer both design and decorating services, which means you get a seamless experience from concept to completion.
