A great presentation isn’t about how much you say, but it’s definitely about how well you say it. The truth is, most presentations fail because they overwhelm, bore, or confuse the audience. But what if there was a simple formula to fix this?

Enter the 10-20-30 Rule, a straightforward yet powerful approach to presentations that helps bring out the best in presentations. Created by Guy Kawasaki, a venture capitalist and former Apple evangelist, this rule is widely embraced in the corporate world, particularly for investor pitch decks, corporate presentations and other business presentations. It’s a formula that helps speakers get their point across efficiently and memorably.

So, what exactly is the 10-20-30 Rule, and how can you use it to transform your presentations? Let’s break it down in an easy way.

The Origin of the 10-20-30 Rule

Before we get into the details, let’s talk about how this rule came into existence.

Guy Kawasaki spent years listening to investor pitches from entrepreneurs seeking funding. He noticed a pattern. most presentations were painfully long, crammed with text, and used fonts so small that he needed a magnifying glass.

He realized that investors don’t want to sit through hour-long presentations filled with unnecessary details. They want clarity, brevity, and compelling insights.

So, Kawasaki devised a simple framework to make presentations more effective and digestible:

  • 10 slides – Because people can't absorb more than that.
  • 20 minutes – Because no one has the patience for a marathon session.
  • 30-point font – Because readability matters more than cramming information.

This formula quickly gained traction and is now widely used in business, education, and public speaking. But why does it work so well?

The Science Behind It

Our brains have limited cognitive load, which means we can only process so much information at once. Overloading your audience with excessive slides, lengthy explanations, and tiny text is a surefire way to lose their attention.

The 10-20-30 Rule forces presenters to be concise, clear, and engaging, making it easier for the audience to understand and remember the key points.

Breaking Down the 10-20-30 Rule

Now, let’s break it down into actionable steps so you can apply this rule to your own presentations.

The 10-Slide Rule

According to Kawasaki, your presentation should have no more than 10 slides. Why? Because people can only retain a limited number of ideas in one sitting.

For example, here’s a suggested breakdown of those 10 slides for an investor pitch deck:

  1. Title Slide – Your company name, tagline, and contact info.
  2. Problem Statement – The issue your business solves.
  3. Solution – Your product/service and how it fixes the problem.
  4. Business Model – How you make money.
  5. Market Opportunity – The size and potential of your market.
  6. Competitive Advantage – How you stand out from competitors.
  7. Go-to-Market Strategy – How you plan to reach customers.
  8. Financial Projections – Revenue forecasts and key metrics.
  9. Team – Who’s behind the company and why they matter.
  10. Call to Action – What you need (investment, partnership, etc.).

This structure ensures that your audience stays focused on the essentials rather than getting lost in unnecessary details.

What If You Need More Than 10 Slides?

If you feel like 10 slides aren't enough, resist the temptation to add more. Instead, consolidate your points. Remember, the goal is to communicate efficiently, not dump everything onto slides.

The 20-Minute Rule

Your presentation should last no longer than 20 minutes. Why? Because attention spans are shorter than ever. Even if you’re given a full hour, Kawasaki suggests wrapping up the main content in 20 minutes to leave time for Q&A, discussion, and interaction.

Here’s how you can structure your 20 minutes effectively:

  • First 5 minutes- Capture attention (problem, solution, impact).
  • Next 10 minutes-  Dive into details (market, strategy, financials).
  • Last 5 minutes- Summarize and end with a strong call to action.

Keeping it tight and engaging ensures that your audience remains hooked from start to finish.

What If You Have More Time?

Use the extra time for discussions, storytelling, and audience interaction rather than stuffing more slides into your presentation.

The 30-Point Font Rule

Now, let’s talk about one of the most common (and painful) mistakes in presentations- tiny text crammed onto slides. According to the Kawasaki’s rule, you should use a minimum 30-point font size.

Here’s why:

  • Readability-  If people can’t read it, they’ll stop paying attention.
  • Conciseness- Bigger fonts force you to keep your message short and impactful.
  • Better Design- Clean slides with fewer words look more professional.

What If You Have a Lot to Say?

That’s what your voice is for! Your slides should support your words, not replace them. If you find yourself adding long paragraphs, cut it down to bullet points or use visuals instead.

How to Apply the 10-20-30 Rule in Real Life

Now that you know the rule, how can you use it effectively? Here are some practical tips:

  1. Start with a Strong Hook- Your title slide and opening words should grab attention immediately. Start with a powerful statement, a thought-provoking question, or an interesting fact.
  2. Keep It Visual- Use images, charts, and graphics instead of walls of text. People remember visuals better than words.
  3. Practice Ruthless Editing- Go through your slides and remove anything that doesn’t add value. If a point isn’t essential, cut it.
  4. Time Yourself- Rehearse your presentation and stick to the 20-minute rule. Avoid rushing through slides, speak clearly and with confidence and always practice your delivery.
  5. Test It on Someone Else- Before presenting, test your pitch on a colleague or friend. If they get lost, simplify it further.

Why the 10-20-30 Rule Works (and Why You Should Use It)
