What aspect of display design does text size impact significantly?

Text size plays a critical role in accessibility because it directly affects how easily individuals can read and understand the displayed information. For people with visual impairments or difficulties, larger text can enhance readability, making it more inclusive and accommodating. Ensuring that text is adequately sized helps to create an environment where everyone, regardless of their visual abilities, can access the content effectively.

While visual aesthetics, design complexity, and navigation ease are important factors in display design, they do not address the core need for inclusivity and comprehension as clearly as accessibility does. For example, a visually appealing design might use small text that could hinder accessibility, illustrating why text size’s impact on accessibility is paramount.
