Accessibility affects more than just design
Starting in June 2025, the European Accessibility Act requires companies to comply with accessibility requirements for individuals with disabilities when offering their products and services.
Accessibility isn’t just a design issue—it impacts every department involved in corporate communication, including Human Resources, IT, Marketing, and Communication.
As many factors are involved in ensuring accessibility, we’ve put together some practical tips and tricks, including helpful links.
What is accessibility?
According to the principles of Diversity, Equity, and Inclusion (DEI), people with physical, sensory, or cognitive impairments should have the same opportunities as those who do not have impairments. First, let us look at the existing barriers to accessibility and how we can address them with user-friendly design.
7 Tips – Practical ways to improve accessibility
Tip 1: Use high-contrast colors
- Use colors with high contrast values to emphasize differences. This applies to backgrounds and fonts.
- Be careful when combining colors and symbols to make it easier for users. Combinations that are easy to distinguish for many people may be challenging for those with impairments.

Tip 2: Make text easy to read
- Choose clear and distinctive font sizes. Headlines should be 18 or 24 points, while body text should be between 9 and 12 points.
- Avoid using all capital letters, which can reduce readability.
- For very small texts, use a light font.
- A good test for readability is the combination B+8,1+I+i+l.
- The DIN standard 1450 on fonts provides more in-depth guidance on this typography.
- Line spacing and layout – As a rule of thumb, line spacing should be 1.5 times the font size. However, you can trust your design skills and vary this when it makes sense.

Tip 3: Design user-friendly links, buttons, input fields, and forms
- Links and buttons: Use distinct colors for these elements to help differentiate them from the surrounding text.
- Remember: Links are for navigating (going), while buttons are for actions (doing). Good design choices make this distinction clearer.
- Input fields should be large enough to be easily recognizable.
- A calendar can make the selection of a date easier.
- Place explanatory texts below the input field, and clearly label required fields.
- Visually highlight active fields and place any error message directly below the field in question.
- In forms, a reading direction from left to right and top to bottom makes them more readable.
- Another way to improve readability is a clear layout
Tip 4: Arrange images and icons clearly
- In our visual world, clear graphics are particularly important.
- Select strong images with a clear central motif.
- Don’t forget alternative text (ALT), which is essential for screenreader users.
- Use icons with high contrast and combine them with text labels when possible.
Tip 5: Use clear language that is easy to understand
- Use simple, clear sentences.
- Use the Flesch Index to test the readability of your text. It measures the average syllables per word and the average sentence length.
- The recommended language level is 45-50 on this scale.
- You can test your content for readability on free tools such as this one – Flesch Index.
Tip 6: Add subtitles and autoplay to videos
- Always subtitle videos. AI tools can generate subtitles quickly.
- Autoplay can increase accessibility
- Make sure your video player supports keyboard navigation.
Tip 7: Check your website for accessibility
- Use free tools such as silktide to check the accessibility of your website.
- If you need to do more regular checks, consider the paid version.
- An excellent example of an accessible website is the online presence of our customer, Merck KGaA, which offers customizable views for different sensory needs.
- The company achieved this using the Digiaccess tool.
Summary
You can use these tips to improve the accessibility of your digital content in just a few steps.
