Website accessibility ensures that websites are usable by everyone, including people living with disabilities. In 2025, creating an inclusive online experience is not only best practice – it’s increasingly expected by users, regulators, and search engines alike.
This article explores what website accessibility means, why it’s important, and how it applies to real-world web design. Whether you’re building a site from scratch or reviewing an existing one, understanding the basics of accessibility can help you make more informed decisions about your online presence.
What Is Website Accessibility?
Website accessibility refers to the design and development of websites that can be used by people with a wide range of abilities. This includes individuals who are:
- Blind or have low vision
- Deaf or hard of hearing
- Living with mobility or motor limitations
- Neurodivergent, including people with dyslexia, ADHD, or autism
The goal is to remove barriers that prevent access to digital content and functionality. When a website is accessible, more people are able to read, navigate, and interact with it comfortably – regardless of the technology or assistance they use.
Why Is Accessibility Important?
- Social inclusion: Accessibility helps create a more equitable internet. It supports equal participation in education, work, and commerce.
- Search engine optimisation: Many accessibility best practices (like good headings and alt text) overlap with SEO techniques.
- Improved usability for all: Accessible websites tend to be easier to use, even for users without disabilities. For example, keyboard navigation benefits power users and those with temporary injuries alike.
Accessibility and Readability
Clear and readable content is a key part of website accessibility. Readability helps users absorb information more easily, and is especially important for people with cognitive differences, low literacy, or visual impairments.
- Use accessible fonts: Choose sans-serif fonts like Arial, Verdana, or Open Sans. Avoid cursive or overly decorative fonts.
- Maintain strong contrast: Make sure there’s enough colour contrast between text and background. Tools like WebAIM’s Contrast Checker are useful here.
- Support dyslexic readers: Avoid justified text, use sufficient line height, and break long blocks of text into smaller paragraphs.
- Font size and spacing: A base font size of 16px is recommended. Let users resize text without layout issues.
- Plain language: Write in clear, straightforward language. Short sentences and bullet points improve comprehension.
Assistive Technologies and Device Access
Many people access websites using assistive tools like screen readers, screen magnifiers, or speech recognition software. To work properly, a website needs to be structured with correct HTML so that these tools can interpret the content.
Accessibility also applies across devices. Users may be browsing from a mobile phone with one hand or using voice commands while driving. Designing for different inputs and screen sizes benefits a wide range of users.
Getting Started with Website Accessibility
If you’re building or reviewing a website, the following are helpful first steps:
- Use semantic HTML elements (like
<nav>,<header>, and<button>) - Add meaningful alt text to all images
- Ensure buttons and links can be accessed using a keyboard
- Check colour contrast and font choices
- Test your site using free tools like WAVE or Accessibility Insights
