TL;DR

Slides That Don't Hurt You

Most presentation slides do the opposite of their intended purpose: they give the speaker something to read and give the audience something to read instead of listening. The 10/20/30 rule is a useful constraint for keeping slides honest.

10 slides
The upper limit for a standard presentation. More than this usually means the content hasn't been prioritized yet. Force yourself to cut.
20 minutes
The maximum speaking time before most audiences lose focus. Even in longer scheduled slots, aim to leave time for questions and breathing room.
30-point font
The minimum font size. If your text is smaller than this, you've put too much on the slide. The audience is reading instead of listening, and you're probably going to read it too.

The purpose of a slide is to give the audience something to look at that reinforces what you're saying, not to display your full script. If every word you plan to say is on the slide, you don't need to be there, they could just read it.

Managing Nerves

Stage fright is a physical response to adrenaline. Your heart races, your palms sweat, your voice may shake slightly. This happens to experienced speakers too. The difference is that experienced speakers have stopped fighting it and started working with it.

A few things that genuinely help:

Structure That Works

People remember stories and arguments, not bullet points. This structure works for almost any presentation, from a class research paper to a workplace pitch.

01

The hook

Start with something that earns attention: a surprising statistic, a provocative question, or a brief story that connects to your topic. Don't start with "Good morning, my name is..." The first 30 seconds matter most.

02

The problem

Why does this topic matter? What happens if nobody addresses it? This is where you create investment in what comes next. The audience needs to care about the problem before they'll care about your solution.

03

The content

Your research, findings, or argument. Organized around a few key points rather than everything you know. When in doubt, cut.

04

The "so what"

How does this change anything for the people in the room? This is the most frequently skipped step and the one audiences remember most. Make it concrete and specific to them.

05

The call to action

What do you want them to do, think, or feel differently after this? End with clarity, not a summary slide that says "Questions?"

Delivery

Handling Questions

The Q&A is often the part people fear most because it can't be scripted. A few things that help:

Record one practice run

Use your phone to record yourself practicing once. Watch it back. You will notice filler words, pacing issues, or physical habits you didn't know you had. One viewing of a practice run teaches you more than ten more rehearsals without it.
