How to build accessibility into your web design process

Accessibility works best when I treat it as part of the design process, not a final check. When I plan for accessibility from the start, the site is easier to use, easier to build, and easier to maintain.

This is the approach I use on real projects.

Start with real users and clear goals

Accessibility begins before I open a design tool.

I ask simple questions early on:

  • Who will use this site
  • What tasks do they need to complete
  • What might make those tasks harder

This helps me avoid assumptions. For example, users may rely on keyboards, screen readers, larger text, or high contrast. Designing with these needs in mind leads to clearer layouts and better content for everyone.

Use structure before styling

Good structure is the foundation of accessible design.

Before focusing on colours or visuals, I think about:

  • clear page hierarchy
  • meaningful headings
  • logical reading order
  • simple navigation

Wireframes are ideal for this. They let me check that the page makes sense without relying on colour or layout tricks. If the structure works in a basic wireframe, it will work better for assistive technology later on.

Design with colour and text in mind

Visual design choices can either support accessibility or work against it.

I pay close attention to:

  • colour contrast between text and backgrounds
  • readable font sizes and line spacing
  • avoiding colour as the only way to show meaning

This does not limit creativity. It encourages better decisions. Clear contrast and readable text improve usability for all users, including people viewing the site on small screens or in bright light.

Think about interaction and focus

Accessibility is not just about how a site looks. It is also about how it behaves.

During design, I consider:

  • how users move through the site with a keyboard
  • where focus should be visible
  • how forms, menus, and buttons behave

Designing these states early makes development smoother and avoids guesswork later. It also reduces the risk of inaccessible interactions being built into the site.

Work closely with development

Accessibility can break down if design and development are disconnected.

I make sure handover includes:

  • clear heading structure
  • guidance on focus states and interactions
  • notes on accessible components and patterns

This shared understanding helps ensure the finished site matches the intent of the design and meets accessibility standards.

Review and improve over time

Accessibility is not a one-off task.

After launch, I look for opportunities to improve based on:

  • user feedback
  • content changes
  • new accessibility guidance

Small improvements over time make a big difference. This mindset keeps the site inclusive, usable, and future-friendly.

If you read this and a question came up, I am happy to talk it through. Everyone is coming from a different angle, but I offer a chat about your project with no obligation. You do not have to have a brief ready. Most people just want to know if what they have in mind is achievable and what it might cost. Let's talk about your project.
