There is a lot to say about the use of text in a presentation deck, but this is for sure: Minimize the number of words per slide. In this e-book Really Bad PowerPoint, Seth Godin suggests to use a maximum of 6 words. In the clip below, former Apple Chief Evangelist Guy Kawasaki talks about his 10-20-30 principle. The 30 stands for 30pt (pt = point) as the minimum font size in a slide.
To make this rule more precise take a look at the image below. Both sentences are written in 36pt, but one sentence is bigger than the other one (click on the image to enlarge.)
- contain simple lines
- have large counters and wide openings
- little or no weight derivation.
I interpret Seth's rule as "maximum one relative simple sentence per slide!" Actually, you could take it a little further: one sentence per slide, one idea per slide. This stuff makes perfect sense! I'll finish for today with two more examples. The first is a sign inside the streetcars in Leipzig.
