Welcome to PowerPoint PowerPoint, I work in TV comedy. As you know, when it comes to comedy, timing is everything.
Presentations are no different.
So, if your assignment is a 30-minute presentation on dinosaurs, you'll know if your presentation is too long or too short. You want time to get across the information you need, but you don't want your audience falling asleep or fidgeting in their seats. Timing your presentation When you select Rehearse Timings, your Slide Show starts running, and PowerPoint starts timing it. The timing is displayed in the Rehearsal dialog box. When the Slide Show comes to an end, PowerPoint will give you the final running time.
