Last month, Janine from a Fortune 500 tech company asked us something that made us pause:
"Why do our presentations feel exhausting even before we present them?"
Our Creative Director didn't miss a beat:
"Because you're treating every slide like a storage unit instead of a communication tool."
As a presentation design agency, we work on dozens of corporate decks, pitch presentations, and keynote speeches throughout the year, and in the process we've observed one common challenge: people confuse more content with more value.
So, in this blog, we'll talk about what are lean presentations & how to create them.
In case you didn't know, we specialize in only one thing: making presentations. We can help you by designing your slides and writing your content too.
What Is a Lean Presentation?
A lean presentation is exactly what it sounds like: no excess fat. Every slide serves a purpose. Every word earns its place. Every visual element moves your message forward. If something doesn't actively contribute to your goal, it doesn't belong there.
But here's what it's not: it's not about making everything minimal for the sake of aesthetics. It's not about having exactly 10 slides because some guru said so. And it's definitely not about dumbing down your content until it's meaningless.
Think of it like this. You know those recipes that list 47 ingredients and take four hours to make? Then you find a version with eight ingredients that tastes just as good in 30 minutes? That's the difference between a bloated presentation and a lean one. Same outcome. Less waste.
Why Lean Presentations Are More Efficient
They Respect Everyone's Time
Time is the only resource you can't get back. When you present, you're asking people to give you their time. A 45-minute presentation with 50 slides isn't just long. It's disrespectful.
A lean presentation says: "I value your time enough to figure out what actually matters." We've timed this. A well-structured 15-slide deck that takes 20 minutes to present accomplishes more than a 40-slide deck that takes an hour. Why? Because people are still paying attention at minute 20. By minute 60, they've mentally checked out.
They Increase Retention and Action
Here's something most people don't think about: the goal of a presentation isn't to present information. It's to change what people think or do. And overloading people with information is the fastest way to ensure they do nothing.
We ran an experiment with a client in financial services. They had two versions of their investor presentation. Version A: 35 slides with comprehensive data. Version B: 15 slides focusing on three key insights. Same content, different depth.
Version B generated 40% more follow-up meetings. Not because it had better information. Because people could actually process and remember it. Their brains had space to think about what they heard instead of drowning in slides.
They Give You Control
Ever been in a presentation where you're on slide 15, you've got 20 more to go, and you're already 10 minutes over time? That's panic. You start rushing. Skipping slides. Saying "I'll move quickly through this section." The audience feels your stress. Your credibility drops.
A lean presentation gives you breathing room. If you've got 20 minutes and 12 slides, you can actually slow down. Make eye contact. Read the room. Answer questions without worrying about the clock. That's not just more efficient. That's more effective.
How to Create a Lean Presentation From Scratch
Start With Your End Goal
Most people start presentations by opening PowerPoint and adding slides. Wrong. Start with a blank document and write one sentence: "After this presentation, I want my audience to ___."
Not "understand our product." That's too vague. Be specific. "Schedule a demo call." "Approve this budget." "Change their customer service process." Whatever it is, write it down. If you can't write it in one clear sentence, you're not ready to make slides yet.
We worked with a healthcare startup that wanted to present to hospital administrators. Their first draft goal was: "Educate them about our solution." That's not a goal. That's an activity. After pushing them, the real goal emerged: "Get them to pilot our software in one department." Now we had something to build around.
Identify Your 3-5 Key Points
Once you know where you're going, figure out the essential stops along the way. What are the 3-5 things your audience absolutely must understand to reach that end goal? Not 10 things. Not everything you know. The 3-5 that matter most.
This is hard. It requires you to make judgments about what's important. But that's the job. You're the expert. You should know what matters.
For that healthcare startup, their key points were: the current process is costing hospitals money, here's specifically how much, our solution fixes this specific problem, here's proof it works, here's what a pilot looks like. Five points. That's the spine of the presentation.
Build Slides That Support Each Point
Now and only now do you open your slide software. Each of your key points becomes a section. Under each section, create the minimum number of slides needed to make that point clear and credible.
One point might need one slide. Another might need three. That's fine. What you're not doing is creating slides just to have slides. Every slide should be able to answer: "Which key point does this support?"
Cut Everything Else
This is where it gets painful. You've got slides about your company history. Your team credentials.
That award you won. That interesting tangent about market trends. And none of it directly supports your key points.
Cut it. All of it. If it's not essential to your argument, it goes in the appendix or in a leave-behind document. Your presentation is not a repository for everything you know. It's a tool for achieving your specific goal with your specific audience.
We had a client fight us on this. They insisted they needed five slides about their company background "for credibility." We compromised: one slide. Guess what? No one ever asked for more. Because when your main content is strong, people assume you're credible.
How to Design Lean Presentation Slides
One Idea Per Slide
This is the golden rule of lean presentation design. One slide, one idea. Not one topic with multiple sub-points. One discrete idea.
If you're explaining a three-step process, that's three slides. If you're comparing two options, that's two slides. When you cram multiple ideas onto one slide, your audience doesn't know where to look. They're reading ahead while you're still talking. They're confused about which element you're referencing. It's cognitive overload.
We redesigned a sales deck for a software company. Their "Features" slide had 12 bullet points. Twelve features on one slide. When we asked which features actually closed deals, they said: "Honestly? Three of them." So we made three slides. One feature, one benefit, one example per slide. Their sales team actually started using the deck instead of avoiding it.
Use Visuals That Clarify, Not Decorate
Here's the test for any visual element in your lean presentation: does it make the point clearer? If you removed it, would the audience lose understanding?
If the answer is no, delete it. That stock photo of a handshake? Gone. That decorative icon that "makes it look professional?" Gone. That chart with 15 data series when you're only talking about one? Simplified or gone.
Good visuals in a lean presentation do heavy lifting. A simple before/after image. A single data point shown large. A diagram that makes a complex concept instantly graspable. These earn their place because they communicate faster than words could.
Embrace White Space
White space scares people. They think empty space means they're not getting their money's worth or that the presentation looks unfinished. Wrong. White space is what makes everything else visible.
We took a client's slide that had a paragraph of text, two charts, and three images, and broke it into four slides with lots of white space. They were nervous it looked "too simple." Then they tested it. The audience comprehension scores doubled. Because people could actually process what they were seeing.
Think of white space like pauses in speech. You don't talk in a constant stream without breaks. Why would you design slides that way?
Limit Your Font Choices and Colors
Here's a simple rule: two fonts maximum. One for headings, one for body text. That's it. And colors? Pick three. Your brand color, a neutral, and an accent. Stick to them religiously.
Every additional font and color is a decision your audience's brain has to process. In a lean presentation, you're eliminating unnecessary processing. You want their brains focused on your ideas, not figuring out why this heading is suddenly in purple Comic Sans.
How to Practice and Deliver Your Lean Presentation
Know It Cold
Here's the paradox: a lean presentation requires more preparation, not less. With 40 slides, you can kind of wing it. There's so much content that you'll cover something. With 12 slides, every moment matters. You need to know exactly what you're saying and why.
Practice your lean presentation until you can deliver it without looking at your notes. Not memorized like a script, but internalized. You should be able to have a conversation around each slide, not recite bullet points.
Build in Flexibility
One advantage of a lean presentation: it's easier to adapt in real time. If your audience asks a question that's relevant to slide 8 but you're on slide 3, you can jump ahead. With 12 slides, that's manageable. With 40 slides, it's chaos.
Build your lean presentation so each section can stand somewhat independently. If you need to skip a section or reorder on the fly, you can. This responsiveness makes you look confident and in control.
Let the Slides Support You, Not Replace You
In a bloated presentation, the slides do the talking. You're just there to advance them and read them aloud. In a lean presentation, you do the talking. The slides support and enhance what you're saying.
This means making eye contact. This means pausing. This means reading the room and adjusting your energy. Your lean presentation gives you the space to actually present instead of just clicking through slides.
The point of making your presentation lean isn't to make it shorter for the sake of being short. It's to make it effective. And effectiveness comes from clarity, focus, and respect for your audience's attention. Cut the excess. Keep what matters. And deliver it like you actually want people to hear it.
