If the presentation is bad, 90% of what it’s said is gone after 30 seconds.
- One message: Bring just one message per slide, in order for the listener to have the full attention on that single message, and not be distracted by other messages.
- Avoid wall of text: the listener cannot both listen and read.
- Size: use size in order to give importance to the elements. Humans give more attention to signaling colors, high contrast colors, moving things and big objects. The headline should not be the biggest thing, since most of the time it’s not the most important part of the slide.
- Contrast: use high contrast on items you want to draw attention to. It’s also important to use a dark background, in order for the speaker to result more important than the presentation itself, other than being more easy on the eyes.
- Reduce the number of objects shown in a single slide. Usually 6 items is the perfect number.
