Creating Outstanding PowerPoints

Avoiding False Advice
Hi Reader, how are things going?
Giving presentations is one of the most important skills to master - no matter which career path you choose.
The way you design your slides can make the difference between a good and a great talk.
Today, I’ll share my simple but powerful tricks to take your PowerPoint presentations to the next level - and I even made a little video for you!
Slide Design
At first, you must nail the basic design principles; otherwise, any advanced addition will just add noise. Let’s go through it super quickly:
Keep a margin Leave some space between your text or pictures and the edge of your slide. Without it, your slides feel cramped and overwhelming.
There is no clear rule for how much space you should leave at the edge of your slide. However, making sure that only the title and possibly a design element are close to the edge will make your slides look less overwhelming and better composed. It may be difficult at times, but it will naturally nudge you to focus on one or just a few key points per slide. Pro tip: one core message per slide, with a maximum of 5–7 elements.
Create a clear visual flow Arrange your content so the audience’s eyes easily know exactly where to go next.If you combine items, keep them in the same relative position each time (e.g., text always below the image it explains).
Limit your fonts and sizes Choose a sans-serif font that matches your topic’s tone. For example, a rounded font can feel friendly and playful, while a sleek, thin font can make your talk feel more serious or modern.
However, use no more than three font sizes across your entire presentation.
Now we can move to some spice that makes your presentation go from good to great.
Using Animations Effectively
Animations should serve one purpose: guiding the audience’s attention.
The simplest and most useful is the “Appear” effect.
I can only urge you to use Appear effects, they will really guide your listeners' attention. You can watch the effect in action in this video I put together for you.
Instead of showing everything at once, reveal each bullet point, image, or diagram only when you talk about it.
This keeps your audience focused on your words instead of jumping ahead and reading the entire slide. It also helps latecomers or people who briefly lose focus to quickly re-engage with the content.
Advanced animations
Fade In Similar to “Appear,” but smoother. You can control the timing so that elements glide into view in half a second for a more polished feel.
I put together a video for you where I show some of the effects and briefly explain how to add them. Don’t worry - you can also watch it on mobile without any issues.
Fly In Ideal for sequences, like showing a stack of documents when talking about your previous publication or documents one after another.
Wipe Perfect for showing processes or growth. For example, you can make an arrow “draw” itself onto the slide or reveal a bar in a chart from left to right, matching the direction of progress.
When using advanced animations, keep them purposeful and consistent—too much variation can feel like a slideshow of random effects.
The Hidden Key: Transitions
Slide transitions are an overlooked tool for professional presentations.
The “Morph” transition in PowerPoint detects identical elements between slides and automatically moves, resizes, or fades them to match their new position.
The left arrow points to where you can find the transitions. So far, I’ve only found the Morph and Push transitions useful—but feel free to experiment yourself. Just be careful not to overdo it, otherwise people might think your slides are straight out of the 1990s, when wild web designs and flashy animations were popular. If you click on “Animations” in the top panel instead, you can open the Animations Pane, which the right arrow points to. This is where you fine-tune your Animation settings. I explain it in the video too.
Here’s how you can use it effectively:
Zoom in on an image – Copy all your images from one slide to the next, move most of them off-screen, and enlarge the one you want to focus on. When you switch slides, the other images will slide away while your main image appears to zoom in naturally.
Create a visual reminder – Keep a small version of an image in the corner as you move on to a new point. This acts like a “breadcrumb” for your audience, reminding them of the bigger picture while you discuss details.
These small transitions can make your presentation feel like a seamless story rather than a disconnected set of slides.
Bonus - Sharing Experiences
These tips work best for in-person talks or recorded videos. In online presentations (e.g., Zoom), movement animations can appear laggy due to data transfer. It’s not a big issue, but too many “Fly In” effects can feel clunky for viewers.
Also, always keep a simplified version ready. Once, I gave a talk where the host’s computer had so little memory that even in-person my slides lagged - it took nearly 30 seconds just to enter presentation mode.
What's a Society Journal? Hi Reader, let’s talk about something that has been essential to the development of the scientific system. They published the first scientific journal ever (despite it being far different from what we call a journal today). I am sure many scientists have even published in “them” without realizing it - I am referring to Society Journals. I bring this up because they might represent one of the best antidotes to predatory publishing and the larger issue of publication...
What's the Right Journal? Hi Reader, where do you normally publish your papers? But why exactly there? It remains one of the most important decisions for your career. If you’re unsure where to publish or if you’re considering switching journals, how do you find a good fit? Here is a pragmatic 7-step framework that should help you make a decision: Step 0 – Build an Initial List First, create a list of potential journals. While several will be top of mind, consider including those that you...
What Makes a Journal? Hi Reader, how many active, peer-reviewed academic journals exist today? There are 40,000! And are you interested in how many papers they publish every day? So, how can you know which journal to publish in? Today, we will discuss five key features of journals to help you differentiate them: What Differentiates Journals With so many journals available, it is easy to think that they differ only by name or impact factor.
