Which new Success Criterion focuses on text spacing?

The focus of the Success Criterion on text spacing is aimed at ensuring that text is readable and accessible to all users, particularly those with visual impairments or reading difficulties. Success Criterion 1.4.12 emphasizes the importance of allowing users to adjust text spacing without loss of content or functionality. This criterion enables adjustments to line height, letter spacing, word spacing, and paragraph spacing, creating a more user-friendly reading experience.

By addressing text spacing, this criterion helps to improve legibility and clarity, which can significantly aid individuals with cognitive disabilities as well as those for whom English is a second language. The goal is to enhance the overall accessibility of text on the web, thereby catering to a wider audience and meeting diverse needs.

In contrast to other Success Criteria mentioned, such as Non-Text Contrast, Identify Input Purpose, and Motion Actuation, these do not focus on text spacing. Non-Text Contrast deals with the visibility of non-text elements, Identify Input Purpose addresses the identification of input fields for better user experience, and Motion Actuation pertains to user interfaces that require specific actions based on motion. Each of these contributes to accessibility in different ways, but they do not specifically target the aspect of text spacing like 1.4.12 does.
