Text can be resized to 200% without loss of content or function.


Some users with visual impairments need to resize text to understand it fully.

To help these users, your website should allow for up to a 200% resize of text without dropping any content or functions. This should be accomplished in a browser and therefore not require any assistive technology.

How to Pass

Users can resize text content in their web browser up to 200% without loss of meaning or function.


  • Images of text (but don’t use images of text, because they don’t resize well)
  • Captions


As all modern browsers allow for resizing text, a website based on good HTML and CSS should comply.

If your website doesn’t resize correctly to at least 200% in a browser, add a feature that enables users to resize text (by CSS) based on three or four predetermined options, including 200%.

Resizing text is different to zooming in (which enlarges text, images and layout without preserving formatting).

Check your website by resizing to 200% in a variety of browsers.

Make sure your resized text doesn’t require the user to scroll horizontally and you fulfil part of 1.4.8 – Visual Presentation for Level AAA.
