What's the best font and size to use for a powerpoint presentation?

Question

The presentation will be in a not-so-large auditorium. Is it true that Verdana is a good font for presentations? Which is better, a dark font on light background or the reverse?

Answer 1

Verdana is suitable for headers. For content, I prefer Arial. As for background, I use dark font on light background, because you'll need to turn off the lights to do your presentation.

Answer 2

Any Sans Serif Font is good. In general dark text on light background is easier to read. The font size should be about 32.
