What is essential for text readability in UD web design?

The emphasis on having sufficient contrast between text and background is crucial for text readability in universal design web design. High contrast ensures that text is easily distinguishable from the background, which is particularly beneficial for users with visual impairments or color blindness. A well-contrasted text not only enhances legibility but also improves the overall user experience, making information accessible to a wider audience.

Inappropriate choices might include using artistic fonts that could compromise clarity or utilizing dark backgrounds exclusively, which, depending on the text color, might not provide adequate contrast. Minimizing the amount of text on a page can help to reduce clutter, but it doesn't inherently improve readability if the remaining text lacks sufficient contrast. Hence, maintaining high contrast serves as a fundamental principle in accessible web design.
