Essential Tips for Creating Accessible UI Designs

Implementing effective accessibility features enhances user experience across diverse audiences, ensuring inclusivity in design.

Make Your UI Design Accessible to Everyone

TL;DR:

  • Use drag-and-drop features to add accessibility elements like alt text without coding
  • Choose templates that already meet basic accessibility standards
  • Follow WCAG guidelines for colour contrast, navigation, and content structure
  • Create proper heading hierarchies to help screen readers navigate your content
  • Test your designs with screen readers to understand the user experience
  • Remember that accessible design improves usability for everyone, not just disabled users

Accessible UI design means creating interfaces that work for everyone, including people with disabilities. This covers everything from colour contrast and font sizes to how screen readers interpret your content.

The good news is that most modern design tools make accessibility easier than ever. You don't need to be a coding expert to create inclusive designs that meet professional standards.

Why Accessibility Matters in UI Design

One in five people has a disability that affects how they use digital products. That's a massive audience you could be excluding with poor design choices.

But accessibility isn't just about disability. Good accessible design helps people using mobile devices in bright sunlight, anyone with temporary injuries, or users with slower internet connections. It's about creating better experiences for everyone.

Essential Accessibility Features

Colour and Contrast

Your colour choices directly impact readability. Text needs sufficient contrast against its background to be readable by people with visual impairments.

WCAG guidelines require a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Use online contrast checkers to verify your colour combinations meet these standards.

Avoid using colour alone to convey important information. If you're highlighting an error in red, also use an icon or text label to make the meaning clear.

Typography and Readability

Choose fonts that are easy to read at different sizes. Sans-serif fonts like Arial or Helvetica work well for digital interfaces.

Keep your font sizes reasonable. Body text should be at least 16px, and avoid using text smaller than 14px anywhere in your interface.

Line height matters too. Space your lines at least 1.5 times the font size to improve readability.

Create clear, logical navigation that makes sense to both sighted users and screen readers. Use proper heading structures (H1, H2, H3) to create a content hierarchy.

Every page should have a clear H1 heading, followed by H2 subheadings, then H3s under those. Don't skip heading levels or use them just for styling.

Add skip links at the top of your pages so keyboard users can jump straight to the main content without tabbing through your entire navigation.

Using Modern Design Tools

Drag-and-Drop Accessibility Features

Most website builders now include accessibility features that don't require coding knowledge. You can add alt text to images, create proper heading structures, and adjust colour contrast using visual editors.

Always fill in alt text fields for images. Describe what's in the image and why it's relevant to your content. For decorative images that don't add information, mark them as decorative so screen readers skip them.

Template Selection

Start with templates that already include accessibility features. Look for themes that mention WCAG compliance or accessibility in their descriptions.

Check that templates have proper heading structures, good colour contrast, and keyboard navigation support. It's much easier to start with an accessible foundation than to retrofit accessibility later.

Testing Your Designs

Use your keyboard to navigate through your entire interface. You should be able to reach every interactive element using only the Tab key, Enter, and arrow keys.

Try a screen reader to understand how your content sounds to users who can't see it. VoiceOver is built into Mac computers, and NVDA is a free option for Windows.

WCAG Guidelines Made Simple

The Web Content Accessibility Guidelines might seem overwhelming, but they're built around four main principles:

Perceivable: Information must be presentable in ways users can perceive. This means providing text alternatives for images, captions for videos, and sufficient colour contrast.

Operable: Interface components must be operable by all users. This includes keyboard accessibility and giving users enough time to read content.

Understandable: Information and UI operation must be understandable. Use clear language, consistent navigation, and help users avoid and correct mistakes.

Robust: Content must be robust enough to work with different assistive technologies. This means using clean, semantic HTML and following web standards.

FAQs

How can I test if my UI design is accessible?
Use automated tools like WAVE or axe DevTools to catch basic issues, then test manually with keyboard navigation and screen readers. The most important step is testing with real users who have disabilities.

Do I need to make my design work with every assistive technology?
Focus on following web standards and WCAG guidelines rather than targeting specific tools. When you use semantic HTML and proper markup, most assistive technologies will work with your design automatically.

What's the difference between AA and AAA accessibility compliance?
AA is the standard most organisations aim for and covers the majority of accessibility needs. AAA has stricter requirements and is typically only necessary for specialised applications like government services or healthcare systems.

How do I handle accessibility in complex UI components?
Use ARIA labels and roles to help screen readers understand custom components. When possible, build on standard HTML elements that already have accessibility features built in.

Jargon Buster

WCAG: Web Content Accessibility Guidelines – international standards for making web content accessible to people with disabilities

ARIA: Accessible Rich Internet Applications – HTML attributes that provide additional context to assistive technologies

Screen reader: Software that reads digital text aloud and describes interface elements to users who can't see them

Semantic HTML: Using HTML elements for their intended purpose (like headings for headings, not just for styling)

Alt text: Short descriptions of images that screen readers can announce to users

Wrap-up

Accessible design isn't a nice-to-have feature – it's essential for creating inclusive digital experiences. Start with the basics like colour contrast and proper headings, then gradually build your knowledge of more advanced techniques.

The tools and templates available today make accessibility much more achievable than it used to be. You don't need to be an expert to create designs that work for everyone.

Remember that accessibility is an ongoing process, not a one-time checklist. Keep learning, keep testing, and keep improving your designs based on real user feedback.
