Reduce the Data on Your PowerPoint Slides-Video PowerPoint Tip
Too Much Data on Your PowerPoint Slides: Your PowerPoint slide deck should be a visual aid to help you explain your point, so if you put too much data on a slide (too much text, too many numbers, or charts and graphs – gasp – Is he saying we can’t use charts and graphs?) you will overwhelm you audience and cause them to attempt to draw their own conclusions about the data.
Your PowerPoint slide should convey a simple concept at a glance.
A good rule is what we call 6X6, which means to limit your number of words per line to six and limit your number of lines to about six as well. That way, no matter how big or small your room is, your audience will be able to read your data, and it will be easy for the audience to instantly understand the concept you are communicating.
