Frequently Asked Questions

What is interior design software?

Naturally, there’s more to the interior design industry than picking out pretty paint or fabric swatches. Designing residential or commercial projects requires acute attention to scale, layout, and measurements—and that’s before you act as a liaison between a bunch of subcontractors. Fortunately, the best interior design software can make a professional’s job a lot easier by offering a convenient place to sketch 2D floor plans, convert them into 3D designs, and execute a big project efficiently, effectively, and elegantly.

How much does the best interior design software cost?

Though the right room design software can be invaluable to your business, you don’t have to spend a small fortune on an app or program. While several options like Homestyler and Planner 5D have lightweight, pared-back options for free, many platforms cost under $100 per month. Or, if you are looking to save, a few systems like Autodesk AutoCAD LT will offer a generous discount if you purchase an annual or multiyear subscriptions upfront.

What do interior designers use the most?

While professional interior designers use a breadth of platforms, computer-aided design (or CAD) software continues to be some of the most sought-after programs. “It’s a widely used program for 2D and 3D drawings across architectural and interior design,” Burnham shares. “Many years ago, one of my early team members taught me the basics of CAD and the rest I learned by doing. To this day, I draw my own furniture plans, and the exercise is what connects me to each project.” That said, most design businesses don’t operate on CAD software alone. For example, Burnham shares that her firm also uses SketchUp, Photoshop, and a task-based service like Asana.

Is there an app for interior decorating?

From touring in-progress projects to attending industry events, a professional interior designer’s day is seldom spent at a desk. Fortunately, it’s possible to design and manage on the go with app versions of popular interior design programs like Autodesk AutoCAD LT, Houzz Pro, and Adobe Express, among others. If your go-to interior design software doesn’t have an app version, don’t worry: Since many programs are cloud- and web-based, you can also use your smartphone’s browser to access your platform—anytime, anywhere.

How to choose the right interior design software for you

Beauty lies in the eye of the beholder—and so do your interior design programs. The first thing you’ll want to figure out is your level of expertise. While established professionals will get a lot of mileage out of a CAD program like Autodesk AutoCAD LT or TurboCAD, decorating beginners might want to look at an easier, more intuitive program like Planner 5D, Spoak, or one of the up-and-coming AI alternatives. The size of your firm is another factor to consider: While sole proprietors have the luxury of selecting software that gels well with their specific preferences, larger companies will need to look into options that allow seamless, real-time collaboration.
