Guy Kawasaki is an American entrepreneur and public speaker from Hawaii. He worked for Apple and helped market the famous Macintosh computer in 1984. The marketing campaign was revolutionary as it showed the computer to be intuitive to use, it made it seem friendly.
Since then Mr. Kawasaki has worked as a business investor, author and speaker. In his years listening to “would be” entrepreneurs pitch him ideas using PowerPoint, he became convinced that most people’s presentation skills were very low and that they could easily be improved. This is how he came up with the 10/20/30 Rule of PowerPoint.
As he states in his website: “This is a simple rule that states that a PowerPoint presentation should have 10 slides, last no more than 20 minutes and contain no font smaller than 30 points.”
When you are presented with new information, taking in a number of new ideas/concepts is difficult, more than 10 is almost impossible. Below, Mr. Kawasaki lists as an example, the 10 PowerPoint slides for a new company seeking funding.

It is possible that you have been given an hour and you want to fill most of it with your presentation. This is a mistake. People arrive late, you might have technical problems or the timeslot is unexpectedly shortened. Make it 20 minutes, keep them interested and have ample time for questions or discussions.
Thirty Point Font
People tend to use fonts that are too small. Maybe because they think that lots of text makes the presentation look more convincing. Also they have lots of text as a reminder to themselves of the material. The advantage of a font that is 30 points in size is that you can’t fit a lot in the presentation, this forces you to edit and to only write the salient points. Being concise and to the point is a big advantage in presentations. A large font has the added advantage of being easier to read by everybody in the room.
