Many people confuse the two. We explain why a good graphic designer isn't necessarily a good web designer, and vice versa.
"I have a cousin who knows Photoshop, he can build my website." This is the most dangerous sentence in digital business.
Both need to understand color and layout. But a web designer must also understand Code Limitations and User Experience (UX). A graphic designer might design a button that looks cool but is impossible to code efficiently.
1. Can one person do both? Yes, "Unicorns" exist, but they are rare. Usually, professionals specialize in one.
2. Which is more expensive? Web design is typically more expensive because it involves coding and maintenance.
3. Do I need both? Yes. You need a graphic designer for your Logo/Brand and a web designer for your Website.
We have distinct teams for Branding (Graphic Design) and Development (Web Design). Get the best of both worlds.
