Frequently Asked Questions
Interior decorator vs. an interior designer: what's the difference?
If you're considering a career in design, it's essential to understand the key differences between an interior decorator and an interior designer.
An interior decorator focuses on the visual appearance and ambiance of a space. Decorators work with color palettes, textiles, lighting, furniture, and accessories to enhance the aesthetic of homes or commercial environments. They do not typically make structural changes.
In contrast, an interior designer will focus on the visual appeal of a space and may collaborate with architects and engineers to plan structural layouts. This means that interior designers often require knowledge of building codes and spatial planning.
Whether you aspire to become an interior decorator or designer, QC Design School's online Interior Design course equips you with the skills and knowledge to build a successful, rewarding career. You'll master the elements and principles of design, color theory, textiles, furniture selection, and space planning to create stunning, functional interiors your clients will love.
How much does an interior designer earn?
According to the Bureau of Labor Statistics, the average interior designer salary is typically around $68,530 per year.* Your earnings will vary based on experience, location and services offered. Earning your professional certification from QC Design School demonstrates your expertise and credibility so that you can charge higher rates. The global design market was valued at $747.75 billion in 2024 and is expected to grow to over $1 trillion by 2032. You can be part of that industry and earn a salary as an interior designer in less than a year!
