Even small UI mistakes can make your design feel messy, unpolished, or hard to use. The good news? Most of them are easy to fix—once you know what to look for.
Let’s go through some of the most common UI mistakes to make—and how to avoid them.
Poor spacing
Does your design feel cramped or uneven? You’re probably not using a consistent spacing system. Adopt a 4pt or 8pt grid. It instantly makes your design feel more organized and professional.
Too many fonts
Using three or four different fonts on one screen? It’s too much. Stick to one or two fonts. Use different weights and sizes to create visual variation. A good rule of thumb is four text styles per screen!
Random alignment
If something feels off and you can’t figure out why—check your alignment. Your elements probably aren’t anchored to each other. Use grids, guides, and consistent spacing to align elements with purpose. Clean alignment = professional feel.
Low contrast
Light gray text on a white background? Stop right there. Poor contrast makes content hard to read and fails accessibility standards. Use a contrast checker and follow WCAG guidelines to ensure your UI is usable for everyone. Accessibility isn’t optional; it’s a must.
Bad color choices
Using too many colors without structure can make your UI look chaotic.
Keep it simple:
Use a limited color palette.
Assign meaning to colors. This helps users navigate your design more easily.
No consistency
Random border radii, colors, and styles across your UI? Inconsistency makes your UI feel immature. Use a style guide or design system to maintain consistency across your interface. Consistency signals professionalism.
Final words
Clean UI isn’t just about beauty; it’s about clarity, usability, and trust. Fixing these small but common UI mistakes will make your design feel more polished and easier to use.
