5 mistakes in presentation design that can put you at risk of failing your pitch

Error 1: Slides are overloaded with text

One of the biggest and most common mistakes is trying to fit all the text you want to say on a slide. Imagine a slide full of small text from top to bottom. What does it make your audience feel? Like closing their eyes and falling asleep. Slides loaded with text are not read, they are not perceived. They create information noise and distract attention from the speaker. A person cannot read small text and listen to you at the same time. Your slide is a visual support for your words, not a complete transcription of them.

How to fix it? Use the principle of “one thought – one slide”. Reduce the text to a minimum – only key points, figures, facts. You are the main source of information, and slides are your assistants.

Mistake 2: Lack of a single corporate identity

A presentation made up of slides of different colours, fonts and styles looks unprofessional and amateurish. It looks like a bad jigsaw puzzle whose pieces don’t fit together. The lack of a unified style indicates inattention to detail and has a bad effect on the perception of the brand as a whole. When each slide looks different, it breaks the audience’s attention and makes it difficult to understand the information. Using a corporate presentation style is not just a designer’s whim, but a powerful branding tool.

How to fix it? Create and use a template with a single colour palette (2-3 colours), one or two fonts, and the same design elements (lines, icons, borders). This will create a coherent image and increase your credibility.

Mistake 3: Poor quality images and visuals

The slogan “a bad image is better than no image” is a road to nowhere. Stretched out, low-quality, tasteless images on the first page of a search kill the professionalism of your presentation. Such bad images in a presentation create the impression of disrespect for the audience and indifference to your project. Visuals are a powerful tool of influence. It is much more memorable than text.

How to fix it? Use only high-quality stock photos from paid or free image banks (e.g. Unsplash, Freepik). Prefer light, natural photos to soulless clipart. Watch the resolution – images should not be blurry or pixelated.

Mistake 4: Lack of visual hierarchy and structure

When all the information on a slide is the same size and boldness, the audience doesn’t know what to look at first. The eyes wander around the slide, trying to find a focal point, but to no avail. The lack of visual hierarchy is a guarantee that the main idea will be lost. Key messages should be the most prominent, and secondary messages should be smaller.

How to fix it? Work with font size, boldness, and colour. The headline should be the largest, the subheading smaller, and the body text even smaller. Use colour to highlight the most important numbers or keywords. Use spaces – they help the composition to breathe and focus attention on the main point.

Error 5: Incorrect font selection

Comic Sans, outdated fonts from the days of Windows 95, or just a terrible mix of the two – all of these instantly destroy credibility. The wrong fonts for a presentation look unprofessional and can even be difficult to read. Some fonts are hard to read from a long distance, while others look ridiculous in a business context.

How to fix it? Use modern sans-serif fonts, such as Open Sans, Montserrat, Roboto. They are clear, easy to read and look neutral. Limit yourself to two fonts: one for headlines and one for the main text. This will create order and harmony. And never use Comic Sans – it’s a taboo!
