If you go over this, it's easy to lose attention when speaking too much instead of showing and telling. Generally, I try to keep my slides under 15 minutes. This will allow viewers freedom to move around and engage with other things during a presentation. Anything smaller and you risk losing people who walk by your presentation.Īs far as actual measurements go, the golden rule is to make sure that eye level is not more than six feet away from the screen. I'd like to see the most of the text at 28 or 32 points, with titles ranging from 36 to 44 points. In most presenting contexts, I find that any font size less than 24 points is too tiny to be read comfortably.
