How Long is the Perfect Presentation?


When it comes to creating a PowerPoint or Prezi Presentation, one of the most common questions is:

“How long should it be?”

The answer to this question is not a simple one, as the length of a perfect presentation or pitch will vary depending on a number of factors.

Let’s analyze five key subtopics that can help determine the ideal length of your presentation.


The first consideration when determining the length of your presentation should be your audience. You need to think about whether they experienced professionals in your field or can they be considered with little knowledge of the topic?

Will they be attending the presentation in person, or will they be viewing it remotely via online presentation tools?

The level of familiarity your audience has with your topic and the context in which they will be viewing the presentation will greatly influence how much information they can absorb and follow.

Presentation Topic

The complexity and difficulty of the topic also plays a big role in determining the overall length of your presentation.

A simple topic with a clear message can be effectively communicated in a shorter amount of time, while a more complex topic may require a longer presentation and a Q&A at the end.


The purpose of your presentation should also be taken into account when determining its length.

Are you trying to inform, persuade or simply entertain your audience? The purpose of your presentation will influence the amount of information that needs to be covered.

Attention Span

The average attention span of an adult is around 5-10 seconds, so it’s important to keep your audience engaged throughout the presentation.

Too much information at once can be overwhelming and cause everyone to tune out at some point. In order to maintain the attention, you should aim to keep your presentation concise and to the point at all subtopics.


It’s important to consider the timing of your presentation, including how much time you’ve been allocated and how much time you need to effectively communicate your message.

It’s better to have a shorter, more focused presentation that leaves a lasting impact on everyone, rather than a longer one that may not be fully understood.


The length of the perfect PowerPoint presentation will vary depending on:

  • audience;
  • topic;
  • purpose;
  • attention span;
  • timing.

A general rule of thumb is to keep the presentation as short as possible while still effectively communicating the information you need.

Most experts recommend limiting your presentations to 15-25 minutes to keep the audience engaged and avoid overwhelming them with too much information.

Remember, it’s not about the number of slides, it’s about the amount of information that needs to be conveyed.
