Even though visual representation of information is preferable, text is still necessary for clarification, prompts, and summaries (see figure).


  • Use calm colours and fonts that don’t clash with your background
  • Keep it simple and minimal. As a rule of thumb: use only 6 words per line and not more than 6 lines per slide.
  • One slide per idea/message. This way the audience can follow what you are saying and what is written on the slide at the same time.

Example slide with listed text kept to a minimum. Only key words are used. Illustration to the right is focal point. Slide and figure: Stan Schouten
