Interior Designer vs. Decorator: What’s the Difference?
If you’ve ever found yourself wondering, “Do I need an interior designer… or a decorator?” you’re in very good company. It’s one of the most common questions I hear from homeowners. The confusion makes total sense—the terms are often used interchangeably—but they do describe different roles. And understanding that difference can help your project feel a lot smoother (and save you a few headaches along the way).
So let’s break it down. No jargon, no judgment, and definitely no design snobbery.
An interior decorator focuses on the finishing touches—the elements that bring a space to life. Furniture, rugs, pillows, art, window treatments, paint colors… all the fun, visible details that make a room feel cohesive and intentional. Decorators work within an existing layout and help refine your style, elevate your space, and avoid those impulse purchases that seem like a good idea at the time but somehow never quite work once they’re home.
If your home functions well as-is and you’re mainly looking to refresh a room, update furnishings, or finally replace that sofa you’ve been side-eyeing for years, working with a decorator may be exactly what you need.
Interior designers, on the other hand, tend to zoom out a bit more—sometimes literally. In addition to selecting finishes and furnishings, designers are trained to think about space planning, flow, functionality, and how a home actually works for the people living in it. That often means getting involved earlier in the process, especially for renovations, kitchen or bathroom remodels, and larger-scale projects that require coordination with architects, builders, and trades. Interior designers also go through formal training and testing. I’m an NCIDQ Certificate holder, which means I’ve completed rigorous exams that assess knowledge, skill, and expertise in interior design—including health and safety standards, building systems, and core design principles. For clients, that translates to thoughtful decisions that aren’t just beautiful, but well considered and appropriate for how a space is actually used.
Designers consider things like space planning, lighting plans, cabinetry layouts, material durability, and how decisions made today will hold up to everyday life tomorrow. In New England homes—where historic details, older construction, and quirky layouts are common—this type of problem-solving can be especially valuable. Many homes across the South Shore and around Boston need thoughtful updates that respect their character while making them comfortable and functional for modern living.
The key difference isn’t about “better” or “worse”—it’s about scope. Hiring a decorator when you really need a designer can lead to frustration and costly do-overs (no one wants to fall in love with a light fixture only to learn it can’t actually be installed). On the flip side, bringing in a designer for a simple refresh might feel like more than you need.
The right fit depends on your project, your goals, and how much support you want along the way.
As a South Shore–based interior designer, my work often blends both worlds. I care deeply about beautiful furnishings and thoughtful details, but those choices are always grounded in function, planning, and long-term livability. Especially in Duxbury and greater Boston homes, good design isn’t just about how a space looks on day one—it’s about how it supports real life for years to come.
At the end of the day, interior designers and decorators both play valuable roles. The most important thing is understanding what your project actually needs and finding a professional whose experience aligns with that vision. And if you’re not sure which direction makes sense? That’s completely okay. A quick conversation can usually clear things up faster than another hour of scrolling design inspiration (though no judgment there - we all do it!).
If you’re planning a renovation, rethinking your home’s layout, or simply looking for guidance on finishes and furnishings, working with an experienced interior designer can make the process feel clearer and far less overwhelming. With nearly 20 years of experience designing complex commercial spaces—and now bringing that same strategic, detail-driven approach to residential projects—I help homeowners across Duxbury, the South Shore, and greater Boston create homes that are both beautiful and highly functional.
