best presentation design tips

PowerPoint is one of the most widely used tools in the world — but most users unknowingly make mistakes that dilute their message and hurt their credibility. At HappySlide Presentations, we’ve reviewed thousands of decks, and these are the most common issues we see.

1. Too Much Text on a Slide - best presentation design tips

Problem: Your audience starts reading instead of listening.

Fix: Use one idea per slide, and highlight keywords only.

2. Poor Font Choices and effects

Problem: Inconsistent or unreadable fonts look unprofessional.

Fix: Stick to 1–2 clean fonts like Calibri, Segoe UI, or Montserrat.

Use font size 24+ for visibility.

3. No Visual Hierarchy

Problem: All elements look the same — the audience doesn’t know where to look. - best presentation design tips

Fix: Create contrast using size, boldness, and color.

4. Low-Quality Images

Problem: Pixelated or generic visuals kill your credibility.

Fix: Use HD images from free or professional sources.

5. Overuse of Transitions & Animations

Problem: Too many animations can distract instead of impress.

Fix: Stick to subtle transitions. Let content shine, not effects.

6. Inconsistent Colors

Problem: Random colors ruin brand consistency.

Fix: Define a brand color palette and reuse it across all slides.

7. Ignoring Data Design

Problem: Raw charts or tables overwhelm your audience.

Fix: Simplify data visuals. Use icons, infographics, and callouts.

8. Reading from Slides

Problem: Presenter reads slides word-for-word.

Fix: Use slides to support your talk, not replace it. Use speaker notes instead.

9. Not Using Slide Masters

Problem: Inconsistent formatting and alignment across slides.

Fix: Use Slide Master View to create templates and save time.
