The Myth That PowerPoint Is the Problem

The 50-Megabyte Insult

I was pacing the floor of an agency in Shoreditch when I saw it happen. A senior account manager was finalizing a monthly report. He was dragging screenshots of dashboards, pasting them into PowerPoint, and shrinking them down until they were the size of postage stamps. He then added a wall of bullet points in a font size that I can only assume was intended for mice.

He saved the file. It was 54 megabytes. He attached it to an email and fired it off to the client.

“I really hate PowerPoint,” he sighed, leaning back in his chair. “It just makes everything look so dense. I wish the client would just log into the live dashboard.”

I had to intervene. It was tragic. “PowerPoint didn’t do this,” I told him, tapping the screen. “You did this. You used a presentation tool as a digital filing cabinet. Sending a 50MB file of unreadable data is not a software issue. It is bad manners.”

We have created a corporate myth that “Death by PowerPoint” is an inevitable consequence of the software. We blame the medium for the message. But the truth is far more uncomfortable. The tool is fine. Our etiquette is atrocious.

The Clutter: Treating Slides as Storage

When we talk about cognitive load, we usually focus on the complexity of the charts. But the sheer density of a slide is just as damaging.

Why do we cram so much onto a single page? Fear. We are terrified that if a metric isn’t visible, the client will think we forgot to track it. So, we add more metrics. We frame this as “thoroughness,” but it is actually Noise. More numbers mean more questions you cannot answer. It introduces massive risk into the meeting.

We clutter the slide because we want the document to serve two opposing purposes: we want it to be a visual aid for a live presentation, and a comprehensive textbook that can be read independently later. You cannot do both. When you try, you get a Frankenstein’s monster that fails at everything.

If the font size is 8, you are hiding something. You are hoping they won’t read it, but you want the credit for having written it. The client looks at a slide with four charts and twelve bullet points, and their brain physically recoils. It is exhausting. It is the opposite of clarity.

The Clarity: Presentation Etiquette

A report is a tool for getting a Decision. A slide deck should be a frictionless glide path to that decision.

Good presentation design is just good manners. It is about respecting the punter’s time and their cognitive limits. Here are the rules of etiquette we must adopt if we want our work to be taken seriously.

First, one idea per slide. If you are talking about the drop in mobile traffic, that is the entire slide. Do not put the desktop traffic on there “just in case.” If they ask about desktop, you can tell them. But do not force them to filter out irrelevant data.

Second, the headline must be the conclusion. We do not write “Q3 Traffic Trends.” We write, “Mobile traffic dropped 14% due to the new checkout bug.”

Third, embrace white space. White space is not a vacuum waiting to be filled with another pie chart; it is oxygen for the brain. It signals to the client that you are confident in the few numbers you have chosen to display.

When you send the “After” version, the file is 2 megabytes. It opens instantly. The client can read it on their phone while waiting for a coffee. They understand the problem, they see the evidence, and they know the proposed action.

Stop blaming Microsoft for your bad habits. Clean up the slides, show some basic etiquette, and watch how quickly the client says, “Brilliant, go ahead.” Sorted.

FAQs

Why do clients zone out when I present my slide decks?

Because you are putting a 500-word essay and three complex charts on a single slide. When you do that, the client has to choose between reading the screen or listening to your voice. They cannot do both. Cognitive overload forces them to tune out.

But I need to include all the metrics to prove I did the work. How do I do that without clutter?

More numbers mean more questions you can't answer. You do not need to prove you did the work on the main slide. Put the exact answer on the slide, and put your math in the appendix. Respect the punter's time.

Is it okay to use animations to reveal data slowly?

No. It is too clever by half. Animations are friction. If the data is so complex that it needs to be spoon-fed via cross-fades, the design is wrong. Just show them the answer.
