Resizing text falls under which accessibility principle?

Resizing text is primarily associated with the principle of perceivable accessibility. This principle emphasizes that information and user interface components must be presented in ways that users can perceive, meaning that the content should be accessible through a variety of sensory modalities.

Text resizing ensures that content can be adjusted according to the user’s needs, which is crucial for individuals with visual impairments or other disabilities who may require larger text to read comfortably. By allowing users to resize text, web content becomes more easily perceivable, ensuring that all users can access and understand the information provided.

The other principles, while important for different aspects of accessibility, focus on different areas. For instance, operable relates to making user interface components accessible, understandable deals with the clarity of information and functionality, and robust refers to creating content that can be reliably interpreted by a variety of user agents, including assistive technologies. However, the primary focus of resizing text aligns specifically with the requirement to make content perceivable.
