Sometimes we struggle to find things and get frustrated when they don’t appear, whether it’s locating your house keys, finding Wally in a sea of Wally impostors or hunting down the partner to that lone sock at the bottom of the washing basket. Or maybe it’s replacing fonts that PowerPoint…
Good PowerPoint presentations are the culmination of many hours of hard work and careful planning. Whether your slides are of the bullet-points-and-comedic-images variety or well-designed masterpieces, the chances are you’ve spent a lot of time researching, fact-checking, structuring and practising that all-important presentation.
Now, what if I were to tell you that, despite all your hard work, there’s a good chance that at least 10% of your audience will have a hard time accessing any of your content? It seems like a real shame for you to have put all that time into a PowerPoint presentation that will frustrate or alienate many in your audience, potentially even that key potential client you’re trying so hard to impress.
Dyslexia affects 1 in 10 adults to some degree. Dyslexia is a life-long specific learning difficulty which, while having no bearing on intelligence, can have an impact on people’s day-to-day activities. People with dyslexia can find tasks involving reading, spelling, organisation and verbal memory more challenging. Symptoms vary from individual to individual and most adults will have developed methods for overcoming the challenges presented in their specific work context. There are times, however, when the way you receive verbal or written information is out of your control, such as company PowerPoint presentations or sales pitches.
Text-heavy PowerPoint presentations are hard work and unengaging for everyone – it’s impossible to listen and read at the same time, so most people will do one or the other, or simply switch off. For people with dyslexia, blocks of text on a white screen is nothing short of a headache. Your audience members will be bored, frustrated, and, critically, will get no benefit from your slides.
So, what can you do to ensure that your slides are engaging and accessible?
1. Avoid big blocks of text in your PowerPoint presentations
This is for everyone’s benefit, especially yours as the presenter. Large blocks of text will be indecipherable for dyslexic audience members, and plain boring for everyone else. Your audience will be working so hard straining their eyes to read what’s on the screen that they’ll ignore you entirely. Instead, minimise the text on the screen and opt for more compelling and visually engaging ways to tell your story. Flowcharts and graphics are a simple way to explain procedures or results in a clear, visual way.
2. Consider the layout of your PowerPoint presentations
Where text is unavoidable, space out the material to avoid dense, cramped paragraphs. Opt for a left-justified alignment and avoid narrow columns or lines that are excessively long. Avoid starting a sentence at the end of a line and ensure line spacing is at least 1.5. Make sure different ideas are separated in a clear and organised manner.
3. Choose a simple font
Keep the font clear and simple. Evenly spaced sans serif fonts, such as Arial tend to be easier to read. There are many alternatives, including Verdana, Tahoma, Century Gothic and Trebuchet. Avoid condensed and cursive fonts. The optimum font size depends on the individual and the screen you’ll be using, but make sure the text is at least size 18. Text should be dark on a light background. Try to stick to one colour for any one section of text and avoid the use of red, pink and green as these colours are often problematic for colour-blind individuals.
Dazzling white backgrounds should be avoided as they can appear too glaring. Cream or a soft pastel colour can eliminate this. Different individuals will have their own colour preference, so it’s difficult to choose the optimum background shade for everyone. As a rule, avoid bright white and ensure there is enough contrast for the text to stand out.
Underlining and italics can make letters and words run together, rendering them harder to read. Instead, opt for bold text in a larger font for headings and emphasis. BLOCK CAPITALS are again more difficult to interpret, so stick to lower case or sentence case.
And there you have it: 5 simple steps to make your presentations more accessible. Fortunately, adopting best practice for a dyslexic audience has the advantage of making presentations easier on the eye, and more compelling, for everyone. Now, go out there and wow your audience!

This two-part series will teach you how to make an effective infographic in PowerPoint. Humans have used pictures to communicate for thousands of years – from pictograms on cave walls to eggplant emojis – so it’s no surprise that we often use infographics to share information.

In our information-rich world, we like to gorge ourselves on data. There are stats and facts for just about any topic you can imagine, just a Google search away. But are data on their own informative enough? When you’re presented with a wall of numbers, are you able to easily decipher the context, background and ramifications of all that information? Probably not – which is why data visualization is becoming increasingly important.
