5 Rules for Better PowerPoint Presentations

The Web is awash with guides for creating PowerPoint presentations, most of which would make awful PowerPoint presentations. Having just finished editing a 125-slide presentation, I have few suggestions that you might not find elsewhere.

1. Never build a 125-slide presentation. Audiences have a limited attention span. Any presentation that takes longer than 15-20 minutes is a losing proposition.

Beware false ranges

“The new BMW 500 arrives loaded with cutting edge technology, everything from in-dash GPS to electronic stability control.”

Did you spot the problem with this sentence? It suffers from a common communication fault called a false range. These sentences usually take the form of “everything from ‘A’ to ‘B’.” The problem arises when the reader has no way of knowing what comes between A and B.

In our example, the reader can guess which technologies are in the new BMW, but it’s unlikely that the car really has every automotive technology available.
