Building the Product

What are the most common design mistakes that make an early product feel amateur, and how do I avoid them?

A starting point

The tells are usually spacing and consistency, not talent: cramped padding, five different button styles, mismatched fonts, and text jammed against edges. As a starting point, pick one font, one accent color, a consistent spacing scale, and generous whitespace, and you'll clear the "looks amateur" bar without being a designer. Polish is mostly restraint and repetition.

  • Use spacing, hierarchy, and font weight, not just color, for visual hierarchy.

Why we picked it Use this as the checklist you run before you ship. It walks through 18 specific tells that make an early product feel amateur (clashing colors, inconsistent buttons across screens, weak visual hierarchy, cramped spacing) and pairs each one with a plain fix. It closes with a short before-you-ship checklist, which is exactly the moment most of these mistakes are still cheap to catch.

18 Common UI Design Mistakes and How to Fix Them

From mockflow.com by MockFlow Long read, 18 mistakes plus a pre-ship checklist

  • Inconsistency is the biggest amateur signal: mixing button styles, colors, and type across screens quietly lowers how much people trust the product.
  • Spacing and hierarchy do most of the work: crowded screens usually just need more breathing room and one clear focal point per view.
  • Keep it as a pre-ship pass: run the closing checklist against each screen before release, since fixing these later costs far more.
