Accessibility is the baseline, not a feature

Accessible design is now expected, not admired. Treating it as the starting point makes products better for everyone.

Across this year’s product design conversations, one shift stands out. Accessibility is no longer described as a feature or a nice extra. It is increasingly treated as the baseline every interface is measured against, much like performance or security. That is good news for the people who rely on accessible design, and it is also good news for product teams, because accessible products tend to be clearer, faster and easier for everyone. Here is how we approach it in our work.

Accessibility helps everyone

Accessible design is often framed around permanent disabilities, and those needs are essential. But the same improvements help many more people. Clear contrast helps someone with low vision and someone reading their phone in bright sunlight. Captions help people who are deaf and people watching on a noisy train. Large touch targets help people with tremors and people using a phone with one hand on a bus.

When teams see accessibility this way, it stops being a niche requirement and becomes part of good usability.

It is cheapest at the start

Fixing accessibility after launch is expensive. Colours have been chosen, components have been built and content has been written. Changing any of them affects many screens.

At the start of a project, the same decisions cost almost nothing. Choosing colours that pass contrast, type sizes that scale, layouts that reflow and flows that work with a keyboard is simply part of good design when it happens in the first sketches.

Content is part of accessibility

Accessibility is not only visual. Plain language helps people with cognitive disabilities, people reading in a second language and people who are tired or distracted. Clear headings help screen-reader users navigate and help everyone scan.

Link text should make sense on its own. Error messages should explain what went wrong and how to fix it. Instructions should not depend on colour or position alone. These are writing decisions as much as design decisions.

Structure that machines can read

Screen readers, voice control and other assistive technologies rely on the structure underneath the visuals. Real headings, real buttons, labelled form fields and meaningful image descriptions make a product usable for people who navigate without a mouse or without sight.

The same structure also helps search engines and the growing number of AI assistants that read pages on people’s behalf.

Testing with tools and with people

Automated tools catch a useful share of common problems, such as missing labels and low contrast. They should run as part of normal development, not only before launch.

But tools cannot tell you whether a journey makes sense. Testing key flows with people who use assistive technology reveals problems no checker will find, such as confusing focus order or instructions that only make sense visually.

Common myths

One myth is that accessible design looks plain. In reality, many of the most beautiful products are also highly accessible. Constraints such as contrast and clear structure often lead to stronger, more confident design.

Another myth is that accessibility only affects a small number of users. Permanent, temporary and situational disabilities together affect a very large share of people at some point, and older users are a growing audience for almost every product.

Where to start in an existing product

If accessibility has not been a priority, start with the most important journeys, such as sign-up, checkout or contact. Fix keyboard access, contrast, labels and error messages there first. Then move these fixes into shared components so they spread across the product.

Set a clear standard for new work so the problem does not keep growing while older parts are improved.

Making it the default

The most effective teams make accessibility part of their everyday standards: in the design system, in definitions of done, in reviews. When it is the default, nobody has to remember to add it at the end.

Baseline checks

  • Check colour contrast in every theme and background.
  • Make every action possible with a keyboard.
  • Write plain, self-explanatory content and error messages.
  • Test key journeys with people who use assistive technology.
