Chances are, older adults constitute a major percentage of your target audience. That’s not going to change anytime soon: The National Council on Aging estimates that the U.S. population of adults aged 65 or older will reach 80.8 million by 2040.
The best practices of web accessibility can help you reach that (growing) market. Here’s how to improve experiences for older adults by following the Web Content Accessibility Guidelines (WCAG) and prioritizing inclusive design.
1. Use color (and color contrast) in an accessible way
One 2023 study found about 25% of adults who are 71 years and older have some degree of visual impairment. That may be a low estimate, depending on how “visual impairment" is defined.
The bottom line: Purely visual content is not accessible for a significant portion of users. WCAG contains requirements called success criteria that establish best practices for using color:
- WCAG Success Criterion (SC) 1.4.1, “Use of Color,” requires that color is not used as the only visual means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. For more guidance, read: Use of Color for Accessibility Explained.
- WCAG SC 1.4.3, “Contrast (Minimum)” requires that the visual presentation of text and images of text has a contrast ratio of at least 4.5:1, with limited exceptions. This makes content more accessible for people with color vision deficiencies (CVD) and other vision issues that impact their ability to read low-contrast text. For additional guidance, read: Designing for Color Contrast: Guidelines for Accessibility.
As you build your website, think about how you use color. Are you leaving people out of the conversation by making assumptions? Does your website use color alone to convey meaning (for example, an instruction that reads “click the green button")?
Color contrast is especially important, and unfortunately, it’s one of the most common WCAG failures. The Bureau of Internet Accessibility provides the a11y Color Contrast Accessibility Validator, a free online tool that tests URLs or color-pairs against WCAG requirements.
2. Make sure your website works when magnified to 200%
Many people with vision disabilities use screen magnifiers or “zoom in" with their browsers. Enlarging the content allows them to read comfortably, but if a website isn’t designed for scalability, it might break.
Two WCAG success criteria can be used to test your content for compatibility with screen magnifying tools:
- WCAG SC 1.4.1, “Reflow,” requires that content can be presented without loss of information or functionality and without requiring scrolling in two dimensions for a set viewport.
- WCAG SC 1.4.4, “Resize Text,” requires that text can be resized up to 200% without loss of content or functionality.
If you zoom in on your content using your web browser’s controls, nothing should break — you should be able to read the content without scrolling in two directions, and everything should appear in the same order.

3. Test your website for keyboard accessibility
Many people don’t use a mouse. They might have arthritis or other conditions that affect their mobility, or they may use screen-reading software to browse the web. In some cases, they simply prefer a keyboard to a mouse — many developers fall into this category — but regardless of why they’re using keyboards, you need to provide them with a decent user experience.
The principles of keyboard accessibility are straightforward:
- Your website must be fully navigable with a keyboard alone.
- You shouldn’t restrict or change the user’s default keyboard shortcuts (hotkeys).
- You should provide a mechanism to skip repetitive elements (read about “skip to" links and their importance for accessibility).
You can perform a basic test by browsing your website without a mouse. Use the arrow keys and the Tab and Shift+Tab commands to move around. Does everything work as expected?

4. Make your website predictable and provide clear instructions
Well-designed websites are predictable: Elements appear in a predictable order from page to page. When people interact with the website, they’re never surprised; they’re completely in control of the experience.
This is especially important if you’re building content for older adults. For example, a hyperlink that reads “learn about our services" shouldn’t take them to their shopping car; That’s not a great experience for any user, but it may be especially frustrating for someone with disabilities.
When web content is unpredictable:
- A person with mobility disabilities may need to spend extra time navigating the website.
- A person with vision disabilities may assume that they activated the wrong hyperlink.
- A person with cognitive conditions may feel confused or overwhelmed.
- Users of all abilities will wonder why the website is working against them.
You can improve predictability by ensuring that navigation elements are repeated in the same order from page to page. Provide hyperlinks with accurate link text and include relevant titles and subheadings on content-heavy pages.
Most importantly, provide clear instructions for forms, shopping carts, and other user interactions. Instructions tell the user exactly what you want them to do and exactly what they can expect when they take those actions.

5. Have an accessibility testing strategy
According to the Centers for Disease Control and Prevention (CDC), about 40% of adults aged 65 or older have at least one disability. Testing your content against WCAG helps you reach those users (and may help you avoid a lawsuit under the Americans with Disabilities Act and other non-discrimination laws).
