How many slides for a 30 minute presentation

30 minute presentations are very common in different situations and scenarios. Some business meetings are arranged for 30 minutes only, and then the PowerPoint presenter can be eventually available for questions or exchange ideas with the audience. Also during a presentation in the classroom, a 30 minute presentation is good to leave more space for other student presentations during the same day. This way, many groups can perform the presentation in a single day.

But the question here is, how many slides for a 30 minute presentation? And of course it is not an accurate answer available since every slide and presenter is different and it could take less or more time. But as a rule of thumb we can get some estimates about how many slides to include in 30 minutes PowerPoint presentation.

Let’s start thinking on this idea. If we have to perform a presentation in 30 minutes and we want to make it on time, let’s imagine every slide should take 2 minutes as most. Then, using 15 slides we’ll be able to present it in a timeframe of 30 minutes.

As a rule of thumb,

  • Estimate how much time do you require to present your slides in average and add 30 more seconds to the result.
  • Then divide 30 minutes by the time spent on a single slide.
  • The result will give you an idea about how many slides for 30 minutes.

Why are we adding 30 more seconds to every new slide? It is very common that we as presenters underestimate the length in minutes for a slide, so adding a few more seconds for every slide, we’ll be safe in the total presentation time.

Why 30 minute if you can present it in 20 minutes and using less slides?

Alternatively, if you need to wrap a presentation in 5 minute presentation or 10 minutes or 20 minutes, then you should be aware that are some well known methodologies, rules and frameworks that are interesting to know in advance. For example, 10/20/30 Rule of PowerPoint is a rule that Guy Kawasaki is evangelizing and that is a very simple concept.

10/20/30 Rule of PowerPoint. It’s quite simple: a PowerPoint presentation should have ten slides, last no more than twenty minutes, and contain no font smaller than thirty points.

by using 10/20/30 rule of PowerPoint for example, you can make less boring presentations, with only 10 slides and no font smaller than thirty point.
