To make presentation slides that do not bore people, put one idea on each slide, cut the text down to a headline plus a visual, and give the whole deck a clear spine so your audience always knows where they are. The slides support what you say. They are not the script.
Most students and fresh grads in Singapore learn the opposite by accident. You copy your essay onto slides, read it out, and watch the room go quiet in the wrong way. This guide fixes that with a small set of rules you can apply to any deck: a class presentation, a pitch, an internship demo, or a work update.
Why most slides put people to sleep
A slide bores people when it does two jobs at once. It tries to be your notes and your visual aid at the same time. So it ends up as a wall of text in 12-point font that nobody at the back can read, while you stand there reading it word for word.
Your audience can either listen to you or read your slide. They cannot do both well. The moment a dense slide appears, they start reading, tune you out, finish before you do, and then wait, bored, for you to catch up. Communication is one of the core skills in the national SkillsFuture Skills Framework, and this is exactly the part it means: getting a message across, rather than only displaying it.
The fix is a shift in what the slide is for. The slide is the poster on the wall. You are the person explaining it. Design every slide so a stranger could glance at it for three seconds, get the single point, and then look back at you.
Rule one: one idea per slide
The strongest rule in slide design is also the simplest. Each slide carries one idea. Not one topic with five sub-points crammed in. One idea.
If you have a slide titled "Results" with a chart, three bullet points, a quote, and a logo, split it. The chart is one slide. The takeaway from the chart is the headline on that same slide. The quote, if it earns its place, is another slide. When you force yourself to one idea per slide, two good things happen: each slide gets simpler, and you stop hiding your point inside a pile of supporting detail.
A quick test: write the single takeaway of the slide as its title, phrased as a full sentence. Not "Sales" but "Sales doubled after we changed the sign-up flow." If you cannot write that sentence, the slide does not have a clear point yet, and neither will your audience.
Rule two: cut the text, show the visual
Once each slide holds one idea, strip the words. Aim for a short headline and one visual. That visual can be a chart, a photo, a diagram, a single number, or a screenshot. The University of North Carolina writing centre makes the same point for spoken presentations: visual aids should reinforce your words, stay simple, and never become something the audience has to decode. You can read their guidance on speeches and oral presentations.
Purdue's writing lab has a practical checklist for slide decks specifically, covering font size, contrast, and how little text a slide should carry. Their guide on designing effective slides is worth a read before your next deck. The short version: big readable font, high contrast, few words, one clear focal point.
Practical moves that kill boredom fast:
- Replace a bullet list with a single chart that shows the same thing.
- Turn a paragraph into one bold sentence and say the rest out loud.
- Use a real photo or screenshot instead of clip art or a stock handshake.
- Show one big number when the number is the point.
- Give charts a plain-English title that states the finding, not "Figure 3".
Rule three: give the deck a spine
People stay awake when they can follow the shape of your talk. A deck with a spine has a beginning that sets up the problem, a middle that walks through it in order, and an end that lands the ask or the takeaway. No spine, and every slide feels random, so the audience gives up trying to track where you are.
Open by telling them what the presentation is about and why it matters to them. Signpost as you go: "first, the problem," "here is what we tried," "here is the result." Close by repeating the one thing you want them to remember. If you want a deeper look at structuring a spoken message, our guide on improving your communication skills at work covers how to order what you say so it sticks.
Here is a plain do and don't table you can check your deck against before you present.
| Do | Don't |
|---|---|
| One idea per slide | Cram a topic with five sub-points onto one slide |
| Headline states the takeaway as a sentence | Vague labels like "Overview" or "Results" |
| Big font, few words, one visual | Paragraphs in 12-point that you read aloud |
| Chart title says the finding in plain English | "Figure 2" with no explanation |
| Clear open, ordered middle, firm close | Slides in random order with no signposting |
| High contrast, dark text on light or the reverse | Light grey text, busy backgrounds, clip art |
| Practise out loud once before presenting | Read the slides for the first time on stage |
Delivery still carries a plain deck
Good slides fail if you mumble at the screen with your back to the room. The deck is half the job. How you speak is the other half.
The basics are boring and they work. Face the audience, not the projector. Pause instead of filling silence with "um". Slow down, because nerves make everyone rush. Look at a few friendly faces around the room. If you get nervous presenting, that is normal and fixable, and our guide on doing public speaking at work without panicking walks through calming the nerves before you stand up.
One more habit that saves plain decks: open strong. The first fifteen seconds set the room's attention level. A sharp opening line, a real question, or a single striking number buys you goodwill for the rest of the talk. The same skill helps when you introduce yourself, which we cover in how to give an elevator pitch about yourself.

A simple checklist before you present
Run through this the night before, not five minutes before you start.
- Every slide passes the three-second glance test.
- Every slide has one idea, stated in the title.
- No slide has a paragraph you plan to read out.
- The deck opens with the problem and closes with the takeaway.
- You have said the whole thing out loud at least once.
None of this needs design talent. It needs restraint. The people who make slides that do not bore anyone are usually the ones who deleted the most.
Common questions
How much text should a slide have?
As little as possible while still being clear on its own. A short headline plus one visual is the target. If you find yourself writing full sentences in the body, move them to your spoken notes and leave the slide with the single point.
How many slides is too many?
There is no fixed number, because one idea per slide means the count follows your content. A tight ten-minute talk might run fifteen simple slides or five dense ones, and the fifteen simple ones will feel faster. Judge by clarity per slide, not total count.
Can I use a template to make slides that do not bore people?
Yes, a clean template helps with contrast and spacing, but a template will not fix a slide with too much text or no clear point. The rules here come first. The template just makes a well-planned slide look tidy. Pick a plain, high-contrast one and resist adding decoration.
Practising all of this in front of real people is the fastest way to improve, and it is exactly the kind of skill we drill in the free six-week FINternship masterclass. If you would rather just start applying these rules, take your next deck and delete half of every slide. Your audience will thank you.
