A pecha-kucha presentation contains twenty slides, each of which appears on the screen for twenty seconds. That’s it. The rules are rigid, which is the point. It’s not nineteen slides or twenty-one seconds. It’s 20 x 20. Presenters make their pitch in six minutes and forty seconds of perfectly timed words and images. Then they shut up and sit down. The format promotes clarity through constraints. And because the slides advance automatically, presenters must convey their message with both elegance and speed.
