Episode #262: Stop Killing Your Professional Presentation With Terrible Amateur Slides

When we are on stage, the visuals can make or break us. People often ask us at Dale Carnegie: how much is too much when it comes to slides? Let’s keep it simple: your visuals should support you, not compete with you. We want the audience’s attention on us, not the screen. That means stripping it back. Paragraphs? No. Sentences? Preferably not. Bullet points, single words, or strong images work best. Say less, so you can talk more.

Follow the two-second rule. If your audience can’t “get it” in two seconds, it’s too complicated. Think clean, punchy and minimal. The six-by-six rule is a good anchor: no more than six lines per slide, and no more than six words per line. And fonts? Go big. Try 44-point for titles and 32-point for text. Then test it from the back of the room. If you can’t read it, no one else can either.

Use sans serif fonts like Arial—they’re easier to read than fancier serif fonts. Avoid shouting at your audience with all caps. Use bold, underline and italics sparingly. These are tools to emphasise—not to overwhelm.

When it comes to builds and animations, either reveal one idea at a time or present all the information at once. But be consistent. Don’t make your content jump around. Confusion is not a learning style.

Images are gold. A sharp, relevant photo can say what three slides can’t. Once your audience sees the point of the picture in two seconds, you can then talk to it. Use bar graphs for comparisons, line charts for change over time, and pie charts for parts of a whole—but keep it simple. Too many variables and even a pie chart becomes a mess.

Colours are the trap most presenters fall into. Black, blue, and green work well. Stay away from red, orange, and grey—especially red, which often disappears on screen. The contrast is everything.

Slide decks reveal the pro instantly. The polished know what works and why. The rest, the great unwashed? They give the game away before they even open their mouths. Let’s not be in that camp. Let’s keep it sharp, tight, and professional.
