Twenty minutes

A full conference talk, a keynote at a smaller event, a guest lecture, or a sermon. Guy Kawasaki’s often-quoted 10/20/30 rule for pitches is built around it: ten slides, twenty minutes, and no font smaller than 30 points.

Twenty minutes is also close to the 18-minute limit of a TED talk, which TED chose because it is long enough to be serious and short enough to hold attention.
