Proven Accessible Web Design Tips to Avoid Costly Mistakes

Imagine visiting a website where the text blends into the background. You try to click a button, but it’s too small to tap. Or worse, you can’t navigate the site at all without a mouse.

For millions of users with visual, motor, or cognitive challenges, these issues aren’t just frustrating, they’re real barriers to access. And they’re more common than you might think.

Accessible website design isn’t just about checking boxes for compliance. It’s about making sure everyone can use and enjoy the web.

When you design with accessibility in mind, you create better experiences for all users, not just those with special needs.

In this guide, you’ll learn:

• What accessibility in web design really means
• Simple, high-impact fixes you can apply right away
• Common mistakes to avoid
• How tools like ZipWP help make inclusive design the default

Whether you’re a beginner or building sites for clients, these website accessibility best practices will help you build with confidence and empathy.

Let’s get started.

Why Web Accessibility Matters

Accessible web design means creating websites that work for everyone, including people with visual, auditory, motor, or cognitive challenges. But the benefits go far beyond special needs.

Accessible design also helps:

• Mobile users dealing with small screens or glare
• People on slow internet or outdated browsers
• Anyone recovering from injury, like a broken wrist
• Older adults with reduced vision or hearing
• Non-native speakers who prefer simpler language

Imagine trying to fill out a form on your phone while holding a coffee or reading a low-contrast page in bright sunlight. Accessibility in web design solves those everyday pain points too.

Ignoring web accessibility design is like locking the door on a segment of your audience. It’s also risky. In the U.S., the ADA requires ADA-compliant web design. Lawsuits over inaccessible websites are rising, especially in eCommerce and education.

In fact, in 2024 alone, plaintiffs filed over 8,800 ADA Title III complaints in federal courts. That’s a 7% increase from 2023 and more than triple the number filed in 2013. And the trend isn’t slowing down. Experts predict that in 2025, these numbers will remain between 8,000 and 9,000.

But accessibility is more than legal compliance. It’s a smart move for your business.

Accessible website design often leads to:

• Better SEO performance
• Higher conversion rates
• Smoother navigation for all users

That’s the core of UX accessibility, building digital spaces that are welcoming, usable, and intuitive for everyone.

By following website accessibility best practices, you’re not just designing for today. You’re future-proofing your site for a broader, more diverse audience.

7 Beginner-Friendly Accessibility Practices

You don’t need to be an expert to start designing for web accessibility. In fact, a few small changes can make a big difference.

These beginner-friendly accessibility practices improve usability for people with special needs, and they also enhance the experience for everyone else.

Here’s how to get started:

• Use high-contrast colors: Make sure text stands out clearly from the background. Aim for a contrast ratio of at least 4.5:1. For example, dark gray text on a white background works well, while light gray on white can be unreadable for many users.
• Add alt text to images: Write short, accurate descriptions for all images. This helps screen reader users understand your content and boosts SEO too.
• Use proper heading structure: Use semantic HTML like H1 for titles, H2 for subheadings, and so on. This creates a clear outline for assistive tools and improves page scanning for everyone.
• Make everything keyboard-accessible: Users should be able to tab through menus, forms, and popups without a mouse. This is critical for both ui accessibility and mobile use.
• Choose readable fonts and sizes: Stick to clean fonts like Arial or Roboto. Avoid overly decorative styles and make sure your body text is at least 16px.
• Label form fields clearly: Don’t rely on placeholder text alone. Use visible labels so users always know what to enter.
• Use descriptive link text: Instead of “click here,” say “view pricing plans” or “download our guide.” This improves ux accessibility and helps screen reader users navigate faster.

These steps align with WCAG best practices and are part of building a truly accessible website design.

Common Accessibility Mistakes to Avoid

Even with the best intentions, it’s easy to overlook parts of accessible website design. Here are some common issues to watch out for:

• Using color alone to communicate: Don’t rely on color to indicate meaning, like showing errors in red without labels. A person with color vision limitations may not notice it. Use icons, labels, or text in addition to color.
• Relying on placeholder text instead of proper labels: Placeholder text disappears when users type, which makes it useless for screen readers and confusing for everyone. Always include visible, persistent form labels.
• Overusing animations or auto-play videos: Movement can be distracting or even overwhelming, especially for users with attention challenges. Auto-play videos also interfere with screen readers and slow down mobile devices. Give users control over media playback.
• Ignoring mobile responsiveness: Accessibility isn’t just for desktop. A site that’s not mobile-friendly can frustrate users who rely on larger buttons, responsive layouts, and proper zooming. Good web accessibility design always includes responsive thinking.
• Forgetting keyboard navigation: If users can’t tab through dropdowns, modals, or interactive elements, your site becomes a dead end. This is a major ux accessibility gap.

To follow true website accessibility best practices, test your design from different perspectives. Use tools like screen readers, try navigating by keyboard only, and view your site on various devices.

That’s how you build a truly accessible web design experience, for everyone.

Tools to Test Your Website’s Accessibility

There are reliable tools that make testing web accessibility easier, even if you’re not a developer. These tools help ensure your accessible website design meets both real-world needs and WCAG best practices.

Here are a few essential tools to get started:

WAVE (Web Accessibility Evaluation Tool)

A free browser extension that visually highlights accessibility design issues right on your site. It flags missing alt text, contrast problems, and structural errors. Great for quick audits and visual learners.

Lighthouse (Built into Chrome DevTools)

Run a full web accessibility audit with performance, SEO, and accessibility scores. It’s ideal for spotting issues related to color contrast, ARIA labels, and heading structure.

axe DevTools

A more advanced option for developers. It offers detailed feedback on accessibility ux design issues and explains how to fix them, making it easier to implement design accessibility guidelines.

Screen Readers (VoiceOver for Mac, NVDA for Windows)

These let you experience your site the way someone with visual limitations might. Navigating your content using only keyboard and screen reader is a practical way to test accessible ui design.

Using these tools regularly is one of the most practical website accessibility best practices. It keeps your site user-friendly and compliant.
