Stop Making “War and Peace” Presentations: How to Create Slides That Keep Your Audience Engaged

A presentation should support your message, not compete with you for the audience’s attention.

One of the most common mistakes presenters make is trying to put everything they intend to say onto their slides. It can feel reassuring: if the information is on the screen, surely nothing will be forgotten. But there is a problem. Your audience can read much faster than you can speak.

By the time you have finished your first sentence, they may already have read the entire slide. Their attention then shifts from listening to you to reading, and the opportunity for genuine engagement begins to disappear.

As I highlight in my 5 Minute Guide to Effective Presentations guide (please get in touch if you'd like a copy), the purpose of a visual aid is to illustrate and reinforce your presentation - not to become a script for it.

Executive delivering a presentation utilising data visualisations to emphasise key points.

Keep It Simple

A good slide is clear, engaging and focused on supporting the point you are making.

That starts with minimal text. Use short bullet points, keywords or phrases rather than lengthy sentences and paragraphs. Your audience should be able to understand the purpose of the slide quickly, while listening to you provide the explanation and context.

Think of the slide as a visual prompt, not a transcript.

Reveal Information as You Need It

Animation can be useful when it has a purpose.

Rather than displaying six bullet points at once, consider revealing each one as you discuss it. This helps direct the audience’s attention to the point you are making and prevents them from reading ahead.

The key is restraint. Animation should support your presentation, not become the presentation.

Let Images Do Some of the Talking

A relevant, high-quality image, chart or graphic can communicate an idea far more effectively than a block of text.

Visuals should have a reason for being there. Blurry photographs, irrelevant stock images, unclear graphs and dated clip art can make an otherwise professional presentation look careless.

Ask yourself: Does this image help communicate my message?

If the answer is no, leave it out.

Be Consistent

Professional presentations generally have a consistent visual identity.

Use the same or complementary fonts, colours, layouts and design conventions throughout. Consistency allows the audience to concentrate on your message rather than noticing unnecessary changes from one slide to the next.

Clean and professional does not have to mean boring. It simply means that the design should work with your content rather than distract from it.

Make Your Slides Easy to Read

Your audience may be sitting some distance from the screen, so readability matters.

Choose straightforward, readable fonts such as Arial or Calibri and make sure the text is large enough to be read comfortably from the back of the room.

Contrast is equally important. Dark text on a light background or, light text on a dark background, can work well when there is sufficient contrast. Avoid combinations that make your audience work to decipher the words.

If people are squinting at your slide, your font is probably too small.

Give Every Slide One Job

One of the most useful principles is one idea per slide.

If a slide is trying to communicate five different messages, the audience has to work out where to look and what matters most.

Instead, give each slide a clear purpose. One slide might introduce a problem; the next might show the evidence; another might present the solution.

This creates a natural flow and makes your presentation easier to follow.

Don't Be Afraid of Empty Space

Empty space is not wasted space.

Trying to fill every available part of a slide often produces clutter. White space or, simply unused space, gives important information room to breathe and makes the content easier to process.

When designing a slide, don't ask, “What else can I fit on here?”

Ask, “What can I remove?”

The Warning Signs of a Poor Slide

Poor slides tend to have a few characteristics in common:

• Too much text

• Small or difficult-to-read fonts

• Low-quality or irrelevant images

• Inconsistent fonts, colours and formatting

• Graphs that don't instantly highlight what you're saying

• Excessive animation and transitions

• Cluttered layouts

• Poor contrast between text and background

• Multiple competing messages

None of these problems necessarily happens in isolation. A slide can become particularly difficult to follow when several appear together.

The solution is usually surprisingly simple: remove anything that does not help communicate your central message.

Don't Turn Your Presentation Into “War and Peace”

Sometimes you genuinely have a lot of information to share.

That doesn't mean all of it belongs on your slides.

Trying to squeeze every fact, statistic, explanation and piece of background information into a presentation can result in what might be described as “War and Peace - the presentation.”

Instead, focus your presentation on the top-line results, key messages and conclusions.

If your audience needs the detail, give it to them separately.

A well-prepared handout can contain additional facts, supporting information, references and further reading for those who want to explore the subject in greater depth. This allows the presentation itself to remain focused and engaging without sacrificing useful detail.

And there is one practical point that is easy to overlook: prepare your handouts in advance and remember to take them with you!

Your Slides Are Not the Star - You Are

The most important principle is perhaps the simplest: your slides should support you, not replace you.

A strong presentation combines a confident presenter with visual aids that clarify, emphasise and reinforce the message.

Keep the text brief. Use meaningful visuals. Maintain consistency. Make everything readable. Focus each slide on one idea. And when there is too much information, move the detail into supporting material rather than overwhelming your audience.

The best slide is not the one that contains everything you know.

It is the one that helps your audience understand, remember and engage with what you are saying.
