- This requirement does not require authors to set any of their content to a specified metric, nor does it intend to imply that all users will adjust the specified metrics. Rather, it specifies that should a user choose to set any of these metrics they can do so without any loss of content or functionality. The author requirement is both to not interfere with a user's ability to override the author settings, and to ensure that modified content is not visually distorted within the adjustment ranges of the requirement.
- Range: Line height (line spacing) to at least 1.5 times the font size.
- Range: Spacing following paragraphs to at least 2 times the font size.
- Range: Letter spacing (tracking) to at least 0.12 times the font size.
- Range: Word spacing to at least 0.16 times the font size.
- Test: Use a browser extension or bookmrklet to test your content.
