- Create a custom PowerPoint theme with a consistent and appropriate color scheme, readable fonts at least 24pt size, and bold keywords for emphasis. Avoid hooked fonts. - Warm colors help call for action and promote optimism while cool colors create a serious tone and relax the audience. - Keep information concise with less than 6 words per line and 6 lines per list. Only display needed information and use charts, tables and graphics to emphasize your message. PowerPoint should supplement the presenter, not be the sole focus.
