The limit to what a human can take in

Today I want to draw your attention to one of my favourite business-related blog posts of all-time. It’s nearly three years old, but it’ll still ring true in thirty-three years’ time. And it’s to do with making slide-show (e.g Powerpoint) presentations.

In The 10/20/30 Rule of PowerPoint on How to Change the World, Guy Kawasaki draws on his experience of being “presented-at” for years. As an editor who’s sat through far too many interminably long press conferences, I can thoroughly sympathise with him. And here’s what he suggests: 10 slides, 20 minutes, and no font under 30 points. It’s a great guideline, and if you think it can’t be done, read his reasoning why it should be.

I’m doing a slideshow presentation about the time many of you will be reading this. I’ll try to follow the rules.
