Creating presentations that are inclusive and accessible is not just good practice; it's essential for ensuring that everyone can engage with your content. Here’s how you can enhance your presentation’s accessibility to reach a diverse audience.
1. Use clear and simple language
Clarity is key. Use straightforward, jargon-free language to ensure your message is easily understood. Avoid complex words and sentences, and keep your slides concise. This approach benefits everyone, but especially non-native speakers and those with cognitive differences.
2. Employ high-contrast colour schemes
To aid visibility, choose high-contrast colour schemes for your slides. Dark text on a light background or vice versa ensures readability for everyone, including those with visual impairments. Avoid overly bright colours and ensure there is sufficient contrast to aid those with colour blindness. Using a tool like Adobe’s Colour Contrast Checker will help ensure your content is readable for all.
3. Incorporate descriptive alt Text for images
Always add descriptive alt text to images, charts, and diagrams. This allows screen readers to convey the content and context of visual elements to those with visual impairments. Be concise but descriptive, providing essential information that enhances understanding.
4. Ensure adequate font size and style
Use a large, readable font size (at least 18-24pt) and a clean, sans-serif typeface like Arial or Helvetica. Avoid decorative fonts and maintain consistent font sizes throughout your presentation. This practice helps those with visual impairments and ensures your text is easy to read from a distance.
5. Add captions and transcripts to multimedia
For videos, include captions and transcripts. This not only benefits those who are deaf or hard of hearing but also aids comprehension for non-native speakers and those in noisy environments. Most presentation software, including PowerPoint and Google Slides, offers easy ways to add these features.
6. Use descriptive links and buttons
If your presentation includes hyperlinks or interactive elements, make sure they are descriptive. Instead of generic text like “click here”, use clear, informative text that describes the destination or action. This approach assists users with screen readers and enhances navigation.
7. Structure content with headings and lists
Organise your content with clear headings and bullet points. This structure helps those with cognitive or processing difficulties to follow your presentation more easily. Use a logical flow and ensure each slide has a clear, focused message.
8. Test with accessibility tools
Before finalising your presentation, use accessibility tools and checkers available in most presentation software. These tools can highlight potential issues and suggest improvements, ensuring your presentation is as accessible as possible.
By integrating these practices, you can create presentations that are not only inclusive and accessible but also engaging and effective for all audience members. Remember, the goal is to communicate your message clearly and ensure that everyone has the opportunity to fully participate in your presentation.
