When I was in high school, deciding what I wanted to be when I grew up, I asked my art teacher, “What is graphic design?” He had the most basic answer: “Anything that involves words.” He pointed to a bag of pretzels and said, “This is graphic design.”
My point of view is anything and everything that involves communication of an idea can be considered graphic design. Some very few examples would be as simple as street signs and complex as websites, brochures, apps, logos and etc. Since graphic design is all about communication, that would also include photography, illustration and painting.
GRAPHIC DESIGN IS…the combination of imagery and typography composed in an engaging way to communicate an idea.
