Well designed presentations use consistent format, wisely chosen colors and type fonts. Poor choices not only communicate poorly but also can distract from your message and you. Keep content simple and short. Use key words instead of complete sentences. Text on each slide should reflect the main points of your presentation.
Bulleted items can introduce or summarize key points.
Text should not recite verbatim what you plan to say. Plan on spending 2-5 minutes or less verbally presenting the content of each slide. Don't squeeze too much info on the page Five to seven words per line and five to seven lines per page is a good starting place. 25 words per page is a good guideline. Headings should be short.
