What is a key factor to improve readability in text design?

The key factor to improve readability in text design is the contrast with the background. High contrast between text and background makes it easier for readers to distinguish letters and words, which is essential for effective communication. When text stands out clearly against its background, it reduces strain on the eyes and allows for faster comprehension.

For instance, dark text on a light background or light text on a dark background provides a clear visual separation, enhancing legibility and ensuring that the text can be read with ease. This principle is fundamental in design, as it directly affects how accessible the content is to the audience.

While using a variety of fonts can contribute to visual interest, excessive font variation can actually detract from readability. Similarly, complex graphics and frequent changes in text size can create distractions that hinder the reader's ability to focus on the text itself. Therefore, maintaining strong contrast between text and its background is widely recognized as a vital component for promoting readability in any form of text design.
