Effective PowerPoint Slide Designs

Tips for Crafting Impactful PPT Presentations

1. Design & Visual Style

Keep it simple and consistent

Avoid clutter, limit fonts and colors, and use only necessary design elements for professional polish.

Use a cohesive color palette

Stick to one or two primary colors with decent contrast to highlight key points.

Embrace white space

Letting slides breathe improves readability and keeps focus on key content.

Limit fonts

To one or two sans serif options like Arial or Helvetica, with a minimum of 24 pt for body text and larger for titles.

2. Text Guidelines

Essential Steps:

  • Follow the 7×7 Rule: no more than 7 words per line and 7 lines per slide.
  • Or try the 5-5-5 Rule: 5 words per line, 5 lines per slide, 5 slides max—ideal for succinct pitches.
  • Guy Kawasaki's 10-20-30 Rule: max 10 slides, 20 minutes total, and at least 30-point font.

3. Visuals & Multimedia

Recommended Structure:

  • Use high-quality images, icons, and infographics to create visual interest and support your storytelling.
  • Simplify charts and graphs use them to clarify data, not clutter it.
  • Use multimedia (videos, animations) sparingly only when it enhances your message, otherwise it risks distraction.

4. Structure & Engagement

Know your audience

And tailor content to their interests, background, and level of understanding.

Frame your presentation as a story

With a clear flow: introduction, development, and conclusion.

Make slides interactive

Where possible polls, Q&A, or prompts boost engagement.

5. Practice & Delivery

  • Rehearse thoroughly, time yourself, and film or read aloud to refine pacing and clarity.
  • Use speaker notes to stay on track and minimize clutter on slides.
  • Anticipate questions and prepare to adapt based on your audience’s responses.
