How many slides for a 15-minute presentation?

A 15-minute presention should have a maximum of 15 slides. This is the right amount of information for audiences to grasp without feeling overwhelmed or bored. If you can give this type of presentation in 10 minutes or less, it’s even better.

How many slides for a 20-minute presentation?

How many slides for a 30-minute presentation?

A 30-minute presentation would require no more than 30 slides. You can use 5-7 bullet points per slide or 8-10 bullet points if the presentation is necessary to convey ideas in great detail. If you are including lots of images and charts to help illustrate your point, then reduce the amount of bullet points used.

It’s a good idea to follow this rule because too many slides can make it challenging to keep track of all the points you are trying to make, and your audience will be more likely to lose interest in what you’re saying or miss important ideas as they go by quickly. It’s also easier for people to focus on your presentation when it’s broken up into smaller sections.

On 30 minute presentations, it is a good idea to leave a few minutes for Q&A. This will allow your audience to ask questions about things they didn’t understand or missed in the part of the presentation. It also gives your audience a reason to get involved in the session.

How many slides for a 40-minute presentation?

For a 40 minute presentation, you should try to keep it to 40 slides maximum, you can dole out some information in detail and leave a bigger chunk of time for Q&A. People will stay attentive when the material is broken up into smaller segments.

You should keep in mind that different people respond to different mediums and will better understand an idea when it’s presented to them in a way they are accustomed to receiving information (i.e. some people benefit from text and others from images, some people need the material broken up into small pieces while others prefer a long, steady stream of information).

It will also depend on the type of presentation you are doing. If it’s a demonstration or special event, then more slides are better (and less time per slide is good). If you’re there to present statistics, research, comparison charts, etc., fewer slides with more information per slide would be best.

How many slides for a 50-minute presentation?

A 50-minute presentation should include no more than 50 slides. You can have more slides than this if you have a very engaging visual presentation with limited amounts of information per slide.

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.

As a general rule of thumb, experienced public speakers or subject matter experts are the ones who feel the most comfortable holding longer presentations and sessions, which allows them to go into greater detail in certain areas.

If you’re new to this kind of work, it might be best to keep your presentations between 30 and 40 minutes and leave the rest of the time slot open for questions from the floor.

A 50-minute presentation would require no more than 20-25 slides, as the only purpose they serve here would be just as a reminder for the speaker to stay on point as he conveys the story to the audience.

How many slides for a 60-minute presentation?

A 60-minute presentation should include no more than 60 slides. If you have a very engaging visual presentation with limited amounts of information per slide, you can have more slides than this.

If the presentation is going to be more interactive, then it’s better to cut down on the number of slides and instead focus on how much each slide will contribute to the overall story you’re telling. You must also leave plenty of time for a Q&A session at the end. 


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. You must know what you want to accomplish with each slide, how long it will take to read the text and absorb information from a chart or graph and how much time you have for Q&A.

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.
