I categorize each of the slides into âflashâ, âfastâ, or âdescriptiveâ. 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.
Most people probably have 20, or 30, or 100 slides for a 1-hour presentation. Trimming this number down to 10 forces you to evaluate the necessity of each and every slide. Just like every element of your presentation, if the slide isnât necessary, it should be cut. It also encourages a presenter to design wisely.
