1.4.12 Text Spacing (Level AA)
Specifies the minimum spacing around the text and requires to do not interfere with user stylesheets and other CSS based client side interventions. Line height, letter spacing or word spacing, spacing underneath paragraphs must be able to adapt to required sizes.

About

For following this guideline, distances between paragraphs, rows, words and characters must be able to be increased to certain values without leading to loss of functionality or loss of content.

Failing at this could result in pieces of text overlapping, hence becoming unreadable. It could also result in components (links or buttons) being moved into places where they can’t be interacted with (outside the viewport or behind other elements).

  • Line height (line spacing) to at least 1.5 times the font size;
  • Spacing following paragraphs to at least 2 times the font size;
  • Letter spacing (tracking) to at least 0.12 times the font size;
  • Word spacing to at least 0.16 times the font size.
