average presentation time per slide
Via Webcast â average time spent per slide = 73 seconds. Live seminar â average time spent per slide = 85 seconds. Note that the webcast delivery method had no audience participation until the presentation was finished and our executive opened it up for questions.
I categorize each of the slides into âflashâ, âfastâ, or âdescriptiveâ. Flash slides take about 30 seconds to deliver, fast slides take about a minute, and descriptive slides about 3 minutes. Then, using these rough estimates, I can calculate how long it should take to make the presentation.
