Resizable Text – Accessibility Guidelines

Accessibility GSA Section 508

Except for captions and images of text, text can be resized without assistive technology up to 200 percent without loss of content or functionality.

Development Considerations

  • Web pages should be designed to be “responsive” to the size of the display on which they are viewed. Performing a 200% zoom should not affect the content or functionality of the page.
  • If you need to specify height and width, using em units in padding can help keep things in proportion because em units are relative to font size.
