Alright, let’s talk real for a second.
A lot of UI designers focus on making things look “nice”… but miss the small details that actually make a product usable.
And no, this is not about colors or Dribbble trends. This is about those tiny decisions that silently kill your product.
I’ve seen this over and over—especially with junior designers. So here are 5 common UI mistakes… and how to fix them properly.
1. Everything Looks Important (So Nothing Is)
This is the classic one.
Big titles. Bold text. Bright colors. Multiple buttons.
Everything is screaming.
The result? The user freezes.
— The brain needs hierarchy. Always.
Fix:
Use one primary action per screen, reduce visual noise, guide the eye intentionally (size, contrast, spacing)
If everything is loud… nothing is heard.
2. Buttons That Don’t Feel Clickable
This one hurts.
You design something that looks beautiful… but the user doesn’t know it’s interactive.
Flat text, no affordance, no feedback.
— If users hesitate, you already lost time.
Fix:
Add clear affordances (color, shape, elevation), Use hover / pressed states and make clickable elements feel obvious
No guessing. No confusion.
3. Inconsistent Spacing (Yes, This Matters More Than You Think)
This is a silent killer.
Margins, paddings, gaps… all slightly different.
Users won’t say “this spacing is wrong” but they will feel that something is off.
— Inconsistency = cognitive friction.
Fix:
Use a spacing system (4pt, 8pt, whatever—just be consistent), Align everything intentionally and respect rhythm and repetition
Clean spacing = perceived quality.
4. Too Many Options (Hick’s Law in Action)
More choices ≠ better experience.
Actually, it’s the opposite.
— The more options you give, the longer it takes to decide.
And sometimes… users just don’t decide.
Fix:
Limit options per screen
Group related actions
Highlight the primary path
Make decisions easy, not overwhelming.
5. Important Actions Are Hard to Reach (Fitts’ Law Ignored)
This is especially bad on mobile.
Your main CTA is small… or far away… or both.
— That increases effort. And effort kills conversions.
Fix:
Make key actions big and easy to tap, place them in thumb-friendly zones and reduce distance and precision needed
Design is not just visual. It’s physical interaction.
Final Thought (Read This Twice)
Good UI is not about decoration.
It’s about:
clarity
intention
reducing effort
And honestly…
Most mistakes are not big design failures. They’re small details nobody paid attention to… So next time you design something, ask yourself:
Is this easy… or just pretty?
Because users don’t care about pretty, they care about effort.
And if your product feels heavy…
They’re gone.
