Keep It Legible
If you must include text in your PowerPoint presentation, go for a large font. Kawasaki says it should be no smaller than 30-point font, with the caveat that if you can determine ahead of time the oldest person in the room, you can knock their age in half and use that as a font benchmark. So, say your oldest audience member is 50, you can use a 25-sized font.
These size suggestions serve a couple of purposes. For starters, you can't fit a whole lot of text on each slide, which helps ax any verbosity you may be inclined to include in written form. This means you, the presenter, are compelled to convey your own narrative while cutting down on distractions.
When it comes to PowerPoint tips, our next and last suggestion is a little off the cuff, but well worth considering.
