Creating effective PowerPoint (PPT) slides is about using the technology to support your message, not to replace it. A common mistake is to treat the slide as a script; instead, think of it as a visual anchor for your audience.
Here are the key points to creating a high-impact presentation:
1. The "Less is More" Rule
Your audience cannot listen to you and read a long paragraph at the same time.
Limit Text: Use the 6x6 rule: No more than 6 lines of text per slide, and no more than 6 words per line.
Use Phrases, Not Sentences: Slides should be prompts for you to speak, not transcripts for the audience to read.
One Idea Per Slide: Don't crowd multiple topics onto one page. If you have more to say, simply add another slide.
2. Design for Clarity
Font Size: Keep titles at 30–48 points and body text at 24–28 points to ensure readability.
Consistency: Use the same font, color scheme, and layout style throughout the presentation. This creates a professional, cohesive look.
White Space: Don't fear empty space. It helps the audience focus on the specific content that is on the slide.
3. Visuals Over Text
Human brains process images much faster than text.
Use Quality Imagery: Use clear, relevant photos, diagrams, or charts instead of generic clip art.
Data Visualization: If you have data, avoid just pasting an Excel table. Use simple, clean graphs that highlight the specific "take-home message" of that data.
SmartArt: Use built-in tools like SmartArt to show relationships between ideas (e.g., flowcharts or cycles) rather than using boring bulleted lists.
4. Logical Structure
Tell a Story: Your presentation should have a clear beginning (the hook/objective), a middle (the evidence/details), and an end (the summary/conclusion).
Clear Headings: Use headings that summarize the point of the slide. Instead of "Methodology," try "Survey Results Confirm Toin Residents' Needs."
5. Presenting with Power
Be the Focus: You are the presentation; the PPT is just the assistant. Don't turn your back to the audience to read from the screen.
Practice: Rehearse with your slides to ensure your timing is correct. A good rule of thumb is about one minute per slide.
Have a Backup: Always save a copy on a USB drive or in the cloud. If the technology fails, you should be able to deliver your core message without the slides.
Quick Summary Checklist
| Feature | Best Practice |
| Slide Count | ~1 slide per minute of speaking. |
| Text | Minimal; use phrases rather than sentences. |
| Fonts | Use clear, Sans Serif fonts (like Arial). |
| Visuals | Use images to illustrate, not just decorate. |
| Consistency | Stick to a 3-4 color palette and uniform style. |
Given that you are creating materials for your computer club and elementary school storytelling, which of these areas (design, structure, or visual aid) do you find most challenging to balance right now?
