Designing for Screen Readers: Best Practices

In today's digital age, accessibility is a crucial aspect of web design. As a responsible designer, it is essential to ensure that everyone, including those with disabilities, can access and navigate your website seamlessly. One of the most important considerations in web accessibility is designing for screen readers. Screen readers are assistive technologies that read aloud the content of a webpage to users who are visually impaired. By following best practices for designing for screen readers, you can create an inclusive and user-friendly experience for all your website visitors.

Understanding Screen Readers

Before we delve into the best practices, let's first understand how screen readers work. Screen readers use text-to-speech synthesis or braille displays to convey the content of a webpage to visually impaired users. They navigate through the page by reading the HTML structure, including headings, links, and other elements. Screen readers interpret the markup and provide users with an auditory or tactile representation of the webpage.

Importance of Designing for Screen Readers

Designing for screen readers is not only about making your website accessible to visually impaired users; it also benefits other users, such as those with cognitive disabilities or those who prefer to listen to content rather than read it. Additionally, designing for screen readers can improve your website's search engine optimization (SEO) by providing clear and structured content that search engines can understand.

Now, let's explore some best practices for designing for screen readers:

1. Use Semantic HTML

Semantic HTML is the foundation of an accessible website. By using appropriate HTML tags, you provide meaningful structure to your content, making it easier for screen readers to interpret. Here are some key elements to consider:

  • Use <h1> to <h6> tags for headings and ensure they are used in a hierarchical order.
  • Use <p> tags for paragraphs and break up content into logical sections.
  • Use <ul> and <ol> tags for lists and <li> for list items.
  • Use <a> tags for links and provide descriptive anchor text.

2. Provide Descriptive Text Alternatives for Images

Images play a significant role in web design, but they are not accessible to screen readers by default. To make images accessible, provide descriptive alternative text (alt text) that conveys the image's purpose or content. Alt text should be concise, descriptive, and relevant to the context. Avoid using phrases like "image of" or "picture of" in alt text, as screen readers already announce that the content is an image.

3. Ensure Keyboard Accessibility

Screen reader users often rely on keyboard navigation to navigate through a webpage. Therefore, it is crucial to ensure that all interactive elements, such as links, buttons, and form fields, are accessible via the keyboard. Here are some tips to achieve keyboard accessibility:

  • Use the tabindex attribute to define the order in which elements receive focus when navigating with the keyboard.
  • Provide a visible focus indicator, such as a highlighted outline, to indicate which element is currently in focus.
  • Ensure that the tab order follows a logical sequence, allowing users to navigate through the page in a meaningful way.

4. Use ARIA Roles and Attributes

ARIA (Accessible Rich Internet Applications) roles and attributes provide additional information to screen readers, enhancing the accessibility of dynamic and interactive elements. Here are a few ARIA attributes to consider:

  • role: Use the appropriate ARIA role to describe the purpose or type of an element, such as role="button" or role="navigation".
  • aria-label and aria-labelledby: Use these attributes to provide alternative text or reference an element that labels another element.
  • aria-expanded and aria-hidden: Use these attributes to indicate the state of collapsible elements, such as menus or accordions.

5. Test with Screen Readers

Designing for screen readers requires testing your website with actual screen reader software. This will help you identify any accessibility issues and ensure that your website is truly accessible. Here are some popular screen readers you can use for testing:


Designing for screen readers is an essential aspect of web accessibility. By following these best practices, you can create an inclusive and user-friendly experience for all your website visitors. Remember to use semantic HTML, provide descriptive text alternatives for images, ensure keyboard accessibility, utilize ARIA roles and attributes, and test your website with screen readers. By prioritizing accessibility, you not only improve the experience for visually impaired users but also enhance your website's SEO and usability for all users.
