How many slides for a 50-minute presentation?

Similar to a 40-minute presentation, a 50-minute presentation can allow you to go into a lot of detail in some places and remain at a high level. You should also feel free to leave out certain information if it is not essential in a particular presentation’s overall scheme of things.

The number of slides for a presentation varies. While too many can bore your audience, not enough will leave them wondering what you’re talking about.

Your slides can serve as visual reminders of your talk and also help you maintain a narrative flow in your presentation.

Remember that slides can and should be used as visual aids, not as the main point of the presentation. The speaker needs to convey that information, not just read it from their slides.
