Excessive squinting, headaches, general irritableness? You may be suffering from PowerPoint Myopia. It’s a condition we’re all victims of. After years of research, we may have found a cure to this appalling malady. Guy Kawasaki espouses the 10/20/30 Rule and thinks 30 point font is the answer. Others vary from 8 point minimums, to 24 point. TJ Walker ironically advocates using no text at all (in front of a PowerPoint that has TJwalker.com written in text) then goes on to vote for 18 point. When creating slides and decks, I don’t have a rule for text size or how big stuff should be. Instead, around our office, we have the 8ft. Rule.
