What are the six types of interior designers

You'd think interior design is just one thing, right? Pick some curtains, call it a day. But nah, it's way more broken up than that. Lots of folks are generalists sure, but the real magic happens when you get someone who actually knows their specific corner of the industry. So whether you're hiring or thinking about jumping into the field yourself, knowing these six distinct types is kinda essential. They're split up by what they actually do day-to-day, where they work, and the weird technical stuff they gotta know.

1. Residential Interior Designer

This one's the most obvious. These designers work on actual homes—houses, apartments, condos, whatever. Their whole deal is making living spaces that actually work for the people living there. We're talking space planning, picking out furniture, figuring out color schemes that don't clash. Lighting too. And here's the thing—they're not just decorators. They'll talk to contractors about knocking down walls or moving stuff around. Real structural changes.

2. Commercial Interior Designer

Commercial folks handle the non-home stuff. Offices, restaurants, hotels, stores, even hospitals. Functionality is huge here, but so is brand identity. Like, a law firm's lobby should feel different than a hip coffee shop, right? They've gotta know building codes inside out—ADA stuff, fire safety, all that boring but critical stuff. Traffic flow matters, ergonomics matters, and they're always thinking about materials that won't fall apart after a thousand people walk on them.

3. Healthcare Interior Designer

This is a super specific niche within commercial design. Hospitals, clinics, dental offices, assisted living places. They don't just guess what looks good—they use actual science. Evidence-based design, they call it. Studies show the right lighting and layout can actually help patients heal faster and feel less stressed. Infection control is a massive deal. Privacy laws (HIPAA) matter. Noise reduction too. And wayfinding? Huge. Nobody wants to wander around a hospital feeling lost and anxious.

4. Sustainable or "Green" Interior Designer

Eco-conscious designers, whatever you wanna call them. These folks are all about minimizing the damage we do to the planet. They pick materials with low VOCs (that's the stuff that off-gasses and makes you sick), hunt down reclaimed or recycled furniture, and try to maximize natural light so you don't need as many lamps. Energy efficiency is their jam. Some have fancy credentials like LEED or WELL certification. And yeah, they can work on both homes and commercial spaces.

5. Universal Design Specialist

This one kinda overlaps with residential and healthcare, but it's its own thing. Universal designers create spaces that anyone can use—doesn't matter how old you are, how tall, or what your physical abilities are. It's not just wheelchair ramps, though that's part of it. Think lever-style door handles instead of knobs, showers without barriers, countertops that can go up or down, flooring you won't slip on. The goal is "aging in place"—staying in your home as you get older. And it doesn't have to look clinical. It can still be stylish.

6. Interior Decorator vs. Interior Designer

People mix these up all the time. A decorator? They're strictly surface-level. Paint colors, fabric choices, furniture arrangement, accessories. They don't touch walls. They don't change floor plans. No structural work whatsoever. Meanwhile, the five types above—residential, commercial, healthcare, sustainable, universal—they're all actual designers. They've trained in spatial planning, building codes, construction documentation. In some states, calling yourself an interior designer is legally protected. You need to pass the NCIDQ exam and everything. So yeah, decorators are kind of the sixth "type" in the sense that they exist in this separate, legally-defined space.

People Also Ask: Common Questions

What is the difference between an interior designer and an interior decorator?

Scope and training, basically. Designers can modify structures—walls, ceilings, electrical stuff. They understand building codes and manage construction projects. Decorators just pick the pretty finishes, furniture, and accessories. They don't mess with the architecture. And like I said, in plenty of US states, you can't legally call yourself a designer without passing that NCIDQ exam.

Which type of interior designer makes the most money?

Commercial and healthcare designers usually pull in more than residential folks. Makes sense—the codes are more complex, the regulations are stricter, the projects are bigger. Corporate office designers and hospitality specialists tend to have the highest median income from what I've seen. Though, if you're a high-end residential designer working with rich clients? You can do pretty well for yourself too.

Can one interior designer be all six types?

Theoretically possible, but rare. You might get a "generalist" who handles both residential and light commercial work. But true expertise in healthcare (infection control is no joke) or sustainable design (LEED certification takes serious study) requires specialized education and experience. Most successful designers eventually pick one or two types to focus on. Builds a stronger reputation that way.

What type of interior designer do I need for my small business?

Commercial designer, full stop. Even if it's just a tiny shop or a little café, a residential designer probably won't know the specifics of commercial flooring, fire-rated materials, egress codes, or ADA requirements. A commercial designer will make sure your space looks good AND doesn't get you sued.

Checklist: How to Choose the Right Type

Before you hire anyone, run through these questions. They'll point you to the right specialist:

• Are you changing walls or floor plans? If yes, you need a designer (not a decorator).
• Is this a business or public space? You need a commercial designer.
• Is the space for medical care? Hire a healthcare specialist.
• Do you have mobility concerns? A universal design expert is critical.
• Is sustainability your top priority? Look for a green or LEED-certified designer.
• Do you only need paint, furniture, and curtains? A decorator is sufficient.
