Presentation Skills: Structure, Slides and Delivery
A presentation is not a speech with slides. The audience can read faster than you can talk, so the moment your slide says everything, you become the slowest way to consume it. This guide covers structure first, slides second, delivery third, in that order of importance.
Key takeaways
- Structure first, slides second, delivery third. Most people work in the reverse order and wonder why it does not land.
- If the slide says everything, you are the slowest way to read it. Slides support, they do not duplicate.
- Open with the conclusion for senior audiences. Building up to it wastes the attention you had at the start.
- On video, raise the camera, light your face from the front, and slow down about 10 percent.
A presentation is not a speech with slides
The moment you put words on a screen, you have introduced a competitor. People read at roughly 250 words a minute and you speak at about 140, so the audience finishes your slide long before you do and then waits, or drifts.
That single fact explains most bad business presentations. The slide carries the full argument, the speaker narrates it, and the audience is doing two versions of the same thing at once. Everything below follows from fixing that split.
The order of work matters too. Structure determines whether the talk succeeds. Slides can only help or hurt a structure that already exists. Yet most people open the deck first, because building slides feels like progress in a way that thinking does not.
Structure: three patterns that cover most work presentations
Answer first (for decisions and senior audiences)
State the recommendation in the first 30 seconds, then support it. "We should move the renewal date to January. Three reasons." Executives are trained to look for the ask, and making them wait eight slides for it is the most common way to lose a decision meeting.
It also protects you against the meeting being cut short, which happens constantly. If you get four minutes instead of fifteen, the important thing has already been said.
Problem, solution, evidence, ask (for proposals)
Establish the problem in terms the audience already feels, propose the change, prove it with evidence, then state exactly what you want from the room. The last step is the one people skip. Ending on "any questions?" instead of "I need sign-off on the budget by Friday" turns a decision into a discussion.
Past, present, future (for updates and reviews)
Where we were, where we are, where this goes. Simple, and it stops status updates from becoming a list of activities with no shape. More on this pattern in impromptu speaking, where it does double duty.
What actually goes on a slide?
One idea per slide. If a slide needs a paragraph, it is a handout, not a slide.
| Instead of | Do this |
|---|---|
| Six bullets of full sentences | One headline that states the point, plus one image, chart or short list |
| A title like "Q3 Results" | A title like "Q3 revenue grew 12 percent, driven entirely by renewals" |
| A chart with everything on it | The one series that matters, with the rest greyed out or removed |
| Your speaker notes on screen | Your speaker notes in the notes pane, where they belong |
| A dense appendix slide shown briefly | A separate appendix section after the closing, for questions |
Write the headline as a full sentence stating the conclusion. If someone flicks through your deck reading only the headlines, they should get the whole argument. That test alone improves most decks more than any design work.
Practical minimums: 24 point text or larger in a room, high contrast, and no more than two fonts. If you are tempted to shrink text to fit, the slide has too much on it.
Charts people can read in four seconds
A chart in a presentation has a different job from a chart in a report. In a report the reader can study it. On screen they get a few seconds while you talk.
- Say the point in the title. "Churn doubled after the pricing change", not "Monthly churn".
- Highlight one thing. Color the series that matters, grey the rest. Do not make people hunt the legend.
- Cut the decoration. Gridlines, 3D effects, shadows and extra axis labels all cost reading time.
- One chart per slide. Two charts means the audience compares them instead of listening.
- Label directly. Put the series name next to the line. Legends force a lookup.
Delivery in the room
Most of the general delivery advice applies, and it is covered in the main public speaking tips guide. Three things are specific to presenting with slides:
Never turn your back. Put a laptop or confidence monitor in front of you so you never need to look over your shoulder. If you must indicate something on the screen, use the hand nearer the screen and keep your shoulders open to the room. Details in the eye contact guide.
Advance the slide, then pause, then talk. A new slide takes the room's attention for about two seconds no matter what you do. Talking through those two seconds means your first sentence is lost. Click, let them look, then speak.
Use a black screen. Pressing B in PowerPoint or Google Slides blanks the screen. When you want the room's full attention on a point, or during discussion, blank it. Nothing pulls focus back to you faster.
Presenting on video calls
Remote presenting is a different medium, not a degraded version of the same one. The audience can leave without leaving, so the tolerance for a slow start is close to zero.
- Camera at eye level. Books under the laptop are fine. Shooting up your nose is the single most common remote mistake.
- Light from the front. A window or lamp facing you. A window behind you makes a silhouette.
- Slow down about 10 percent. Compression and lag eat the fast parts of speech and consonants suffer most.
- Say the shape up front. "Three things, about eight minutes, then questions." Remote audiences need to know when the end is.
- Break every three to four minutes. Ask something, take a poll, use a name. Uninterrupted monologue is where remote attention dies.
- Turn off self-view. Watching your own face degrades your eye contact and your concentration.
- Stand if you can. It changes your voice and energy even though only your top half is visible.
Also share a specific window rather than your whole screen, and close everything that produces notifications before you start.
Handling questions
Q and A is where presentations are won and lost, because it is the part you cannot script and the part senior people pay most attention to.
- Repeat or rephrase the question. Everyone hears it, you get thinking time, and you can gently reframe a loaded one.
- Answer the question asked. Answering a nearby easier question is transparent and it costs trust.
- Keep answers under 90 seconds. Longer and you are presenting again. The PREP framework keeps them tight.
- Say when you do not know. With what you would need and when you will follow up. This gains credibility rather than losing it.
- Close after Q and A, not before. Take questions, then deliver your prepared final line so the meeting ends on your message.
Prepare for questions specifically: write the eight hardest ones you could be asked and answer each out loud once. Most "surprise" questions in a work context are entirely predictable.
A realistic preparation timeline
| When | What |
|---|---|
| Day 1 | Write the one-sentence ask and the three supporting points. No slides yet. |
| Day 2 | Write slide headlines only, as full sentences. Read them in order and check the argument holds. |
| Day 3 | Build the slides. Charts last. |
| Day 4 | First full run out loud, standing, timed. Cut whatever put you over. |
| Day 5 | Run it for one colleague. Write the eight hardest questions and answer them out loud. |
| Day 6 | One clean run. Test the room, the cable and the clicker. |
The full method behind days 4 to 6 is in the five-session practice routine.
Frequently asked questions
How many slides should a 20-minute presentation have?
There is no fixed rule, but 10 to 20 slides works for most business talks. Count minutes per idea instead of slides: a slide you speak to for 10 seconds and a slide you speak to for two minutes are both fine.
How much text should be on a slide?
One idea per slide, expressed in six words or fewer where you can. If a slide needs a paragraph, it is a handout, not a slide.
How do you present well on a video call?
Raise the camera to eye level, light your face from the front, and speak about 10 percent slower than you would in person. Compression and lag eat the fast parts of your speech.
