According to the 10-20-30 rule for presentations, what should be the font size for the text?

The 10-20-30 rule, established by Guy Kawasaki, is a guideline for creating effective presentations, particularly when using visual aids like slides. The rule suggests that slides should contain no more than 10 slides, should last no longer than 20 minutes, and should use a font size of at least 30 points.

The rationale behind choosing 30 points or larger for the font size is to ensure readability and to maintain audience engagement. A larger font size helps ensure that the text is legible from a distance, making it accessible to all audience members, regardless of where they are seated. This approach also encourages the presenter to focus on essential points rather than cluttering the slides with excessive text, promoting a clearer and more impactful delivery of information.

This focus on simplicity and legibility contributes to more effective communication, as it allows the audience to easily absorb and retain the information being presented. Therefore, using a font size of 30 points or larger is crucial for adhering to best practices in presentation design, facilitating a better learning experience for the audience.
