How to design CTAs for accessibility and screen readers?

You're designing a button for your email and you think about how it looks on your screen. But someone using a screen reader needs different information. They can't see your colors or your button shape. They hear words. That's why accessible CTAs matter for everyone, not just people with disabilities. Clear link text, strong contrast, and decent tap targets make your CTA work in every context.

Start with your link text. Say what it does. "Download the 2024 guide" tells your reader what happens next. "Click here" doesn't. The button text is your first accessibility layer. Next, contrast. Your button text and background need at least a 3 to 1 contrast ratio to meet WCAG standards. Most colors fail this without a tweak. On mobile, you need that 44x44 pixel minimum tap target we talked about. If your button's text doesn't explain the action clearly, add an aria-label. That's the thing screen readers actually announce. And never, ever rely on color alone to say "this is a button." Use shape, text, or position too.
