How many slides for a 10 minute presentation and the 3-2-1 rule for presentations

Preparing for a presentation can be a daunting task for anyone. If you are presenting to an important client, a large audience, or a group of classmates, it can feel like it's impossible to figure out where to start.

However, with some planning and preparation (and help from wonderful blog posts like this one!), you can go into your presentation with confidence and deliver your message effectively. So don't worry, we've got you covered!

Here are some tips to help you determine how many slides you need for your presentation, based on the length of time you have to speak.

How many minutes per slide for a presentation?

A general guideline is to allocate approximately 2 minutes per slide. This means that for a 10-minute presentation, you should aim for around 5 slides, plus or minus 1 to 2 slides. Try the calculator below or read the 3-2-1 Rule for presentations for a more in-depth guide on how to budget the number of slides for your next presentation.

How many slides for a presentation? (Calculator)

Here is a calculator that can help you budget how many slides you will need for your presentation depending on the time you need to present for. Just type in how long your presentation needs to be in minutes, and it will give you a suggestion for the number of slides.

minutes
Your presentation should have ...
5 slides, plus or minus 1 to 2 slides

While this is a simple calculation, the number of slides in your presentation can vary widely depending on the complexity of the content, the type of presentation, and the goal of the presentation.

For example, a slide deck for an 18 minute TED talk might only have a few slides with very little text, while the slide deck for a ~18 minute research presentation might have 30 slides (although many of them could be backup slides in an appendix).

Here are some additional rules for thinking about the number of slides in a presentation: 

  • When using this calculator, enter the amount of "presentation" that you will be actively presenting. Don't worry about time that will be spent in discussion or Q&A
  • If you are presenting data, try to reduce the complexity of the presentation itself and put most of the charts and data in an appendix.
  • If you are creating a presentation as a 'leave-behind' that can stand by itself, you should aim for the higher end of these recommended ranges. If you are creating a presentation that is a visual aid for you to tell a story, you should aim for the lower end of these ranges.

Follow the "3-2-1 Rule" for presentations

Follow the "3-2-1 Rule" for presentations. THREE takeaways for your audience, TWO minutes to present a slide, ONE idea per slide

While every presentation is different, and everyone's presentation style is different, the 3-2-1 rule is a good rule of thumb to plan the overall structure of a presentation. This applies whether you are a management consultant advising Fortune 500 CEOs or if you're a student making a high school presentation.

Here are the three components of the 3-2-1 Rule:

  • THREE takeaways for your audience
  • TWO minutes to present a slide
  • ONE idea per slide

As you create the outline for a new presentation or revise an existing presentation, you should ask yourself:

  1. What are the 3 things that I want my audience to remember from my presentation when I am done talking (or they are done reading)?
  2. How many slides will I have to make these points? Divide the time of your presentation by 2 to get a general idea for how many slides you will need in your presentation
  3. What is the main idea for each slide? A common refrain among professional consultants is that you should be able to understand the story of a slide deck just by reading the slide titles

Regardless of the length of the presentation, you should always start the planning or revision process by thinking about the key points that you want your audience to take away (that's the whole point of a presentation, really!).

Then, if you are making a 10 minute presentation, you probably need 5 slides plus or minus 1 to 2 slides depending on the style of presentation or depth of content. If these are slides to start a conversation, you probably need fewer. If these are slides to present your takeaways from a research project, you may need more (and maybe some backup slides in an appendix, too).

From there, write out the key idea for each slide. One great way to do this is to make the key idea of the slide the slide title itself. Then, you should be able to read all of the slide titles one after another and make sure that they deliver a cohesive story.

If you need a quick way to get started, try using an AI presentation maker to generate the first draft of your presentation.

How many slides do I need for a 5 minute presentation?

If you are making a 5 minute presentation, your goal should be for your audience to only remember one or two key ideas, so you should have 2 or 3 slides max.

  • For work: Try to create 1 slide with your main idea, along with 1 or 2 backup slides that can present supporting data like a data visualization, customer quotes, or an execution plan.
  • For sales: Try to create 1 slide to focus your discussion, along with 1 or 2 backup slides that can help answer customer questions.
  • For school: Try to create 1 slide for each key point in a story or research idea and make sure the key points can tie themselves together in a conclusion.
  • For storytelling: Try to create one slide with a poignant story, quote, or data point to help your audience remember the key message from your presentation. Then, you may also want to have 1 or 2 slides to build up to the idea or present conclusions from that idea.

How many slides do I need for a 10 minute presentation?

In a 10 minute presentation, you should aim for 5 slides, plus or minus 1 to 2 slides. Here are some suggestions based on the type of presentation:

  • For work: Create 2 or 3 primary slides to present your key points (e.g., a framework slide, a key data visualization, or a plan of action), and 2 to 3 additional slides with supporting data or examples.
  • For sales: Create 3 main slides that highlight the benefits of your product or service (e.g., problem statement, customer story, value proposition), and 2 additional slides for testimonials or data to help support the conversation if your customer wants to dive deeper on a specific topic.
  • For school: Create 2 or 3 main slides for your key arguments or findings, and 2 to 4 additional slides for evidence or further explanation. A book report, for example, could have a slide with a plot summary and another slide with the key themes in the story.
  • For storytelling: Create 3 main slides that build a narrative arc (introduction, rising action, conclusion), and 2 additional slides for impactful quotes or visuals. The key slides for a TED talk might be an image to tell a captivating story, a slide to present a shocking statistic, and end with a story about a hopeful new project to solve a key problem.

How many slides do I need for a 15 minute presentation?

For a 15 minute presentation, aim for 7 slides, plus or minus 1 to 2 slides. Here are some suggestions based on the type of presentation:

One thing to note here is that the length of a storytelling slide deck does not need to get much longer for 15, 20, or 30 minute presentations.

How many slides do I need for a 30 minute presentation?

At 30 minutes and above, it becomes increasingly likely that you won't be expected to present for 30 minutes straight, and the "presentation" itself becomes more of a conversation aid that can support a back-and-forth discussion about a topic.

For these types of presentations, you should calculate how much time is going to be used in a "single-sided" presentation and how much time will be used in discussion. If you expect 10 minutes of your 30 minute presentation (or more) to be a discussion, you should refer to the section on "How many slides do I need for a 20 minute presentation?"

If you think you will need to present for a full 30 minutes, here is our recommendation for the number of slides you need, based on the type of presentation.

For a general 30-minute presentation, aim for 15 slides, plus or minus 2 to 3 slides.

How many slides do I need for a 45 minute presentation?

45 minutes is a long time for a one-sided presentation, so it's more likely your presentation will be used to facilitate a back and forth conversation (which may use slides as support to make a strategic decision), or present an in-depth look at research data and conclusion (which may use slides with in-depth data analysis).

For these types of presentations, you should calculate how much time is going to be used in a "single-sided" presentation and how much time will be used in discussion. If you expect half of the time to be a discussion, you should refer to the section on "How many slides do I need for a 20 minute presentation?"

If you think you will need to present for 45 minutes, here is our recommendation for the number of slides you need, based on the type of presentation.

For a general 45-minute presentation, aim for 20 slides, plus or minus 3 to 5 slides.

How many slides do I need for a 60 minute presentation?

60 minutes - one hour - is a very long time for a one-sided presentation. For these types of presentations, you should calculate how much time you expect to give a "single-sided" presentation and how much time will be used in discussion or Q&A. 

If you expect half of the time to be a discussion, you should refer to the section on "How many slides do I need for a 30 minute presentation?"

If you think you will need to present for 60 minutes, here is our recommendation for the number of slides you need, based on the type of presentation.

For a 60-minute presentation, aim for 25 slides, plus or minus 3 to 8 slides.
