5 Common Presentation Design Mistakes and How to Avoid Them

Whether you're preparing a presentation for work or a special event, the design is just as important as the content. The design can either enhance your message or distract your audience, and it’s easy to fall into common traps. 

Below are five of the most common presentation design mistakes and some tips on how to avoid them.

1. Overloading Slides with Text

2. Inconsistent Design Elements

3. Poor Colour Combinations

4. Overusing Animations and Transitions

5. Ignoring Visual Hierarchy


1. Overloading Slides with Text

One of the biggest mistakes people make is creating slides with too much text. We’ve all seen those slides that look more like a novel than a visual aid. It's overwhelming, hard to read, and can very quickly disengage your audience.

How to avoid it: Keep your slides clean and focused. Only include the most essential information, the rest can be placed into the notes section to help guide you if you need. 


2. Inconsistent Design Elements

Inconsistency can make or break a presentation. Different fonts, clashing colours, or varying slide layouts can make your presentation feel chaotic and unprofessional.

How to avoid it: Stick to a consistent theme for your entire presentation. Use your brand guidelines or if you’re creating a new presentation, choose a font pairing and colour scheme early on.


3. Poor Colour Combinations

You might love neon pink and lime green, but that doesn’t mean they should headline your presentation. Bad colour choices can hurt readability and make your slides hard to follow. Sometimes, the colours can even clash with the projector or screen, making it difficult for your audience to view the presentation.

How to avoid it: Opt for high-contrast colour schemes that make your text easy to read. Dark text on a light background (or vice versa) is a safe option. Going one step further, test your presentation on the display screen when possible to ensure everything looks clear.


4. Overusing Animations and Transitions

Animations can add flair, but they can also distract from your message if overused. We've all been in a presentation where every slide transition was a spinning cube or every bullet point came bouncing in. This can make your presentation feel cheesy rather than professional.

How to avoid it: Use animations and transitions sparingly. Stick to subtle effects like fade-ins, and only use them when they serve a purpose (like revealing new information). The simpler, the better.


5. Ignoring Visual Hierarchy

When all the elements on your slide are competing for attention, it’s hard for the audience to know where to focus. If there’s no visual hierarchy, your main points can get lost in the shuffle.

How to avoid it: Use visual hierarchy to guide your audience. Make your headlines/titles larger than your body text, use bold fonts for key points, and use colour to highlight important information. Arrange elements in a way that naturally draws the eye to the most important parts of the slide.


In the end, great presentation design is all about balance. Keep your slides clean and focused, and let your design support the message you’re delivering, not distract from it. By avoiding these common mistakes, you’ll ensure that your audience stays engaged and that your message comes through loud and clear.
