How long does it take to become an interior designer?

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

While the terms interior designer and interior decorator are often used interchangeably, they each have different job descriptions and duties. Interior designers are required to have more in-depth education and their duties can include making structural design changes and understanding building regulations and codes. Interior decorators, on the other hand, don't work with architects or other professionals to create new spaces, but instead, work with clients to decorate spaces that already exist.
