7 Common Mistakes Beginner UI/UX Designers Make and How to Avoid Them

Over the years, we’ve seen the same mistakes made by beginners. Here are seven of the most common:

1. Too many elements on one screen
   Solution: Apply the “one screen — one goal” principle.
   
2. Ignoring hierarchy
   Everything looks equally important. Solution: Start with a wireframe and clearly define priorities.
   
3. Using random colors
   Solution: Create a semantic color system (primary, success, warning, etc.).
   
4. Lack of spacing system
   Solution: Create an indentation scale (4, 8, 16, 24, 32 px) and stick to it.
   
5. Working without user flow
   The designer draws screens one at a time. Solution: Always draw the full user journey before creating screens.
   
6. Ignoring mobile-first
   First they make a desktop, then they “squeeze”. Solution: Start the design on the smallest screen.
   
7. Not testing on real people
   The most common mistake. Solution: Even 3–5 guerrilla tests provide a huge amount of insights.

In our guides (especially in Zenith Pass and Flux Guide) we analyze in detail how to avoid these mistakes already at the stage of the first projects.
