According to design recommendations, how many typefaces should be used for main text?

Using one typeface for main text is recommended because it promotes clarity and enhances readability. When a single typeface is employed, it allows for a cohesive and unified look, which is essential in materials related to fire and life safety education where clear communication is crucial. A single typeface helps maintain a focused visual hierarchy, allowing readers to easily navigate the content without being distracted by multiple styles. This approach also minimizes visual clutter, making the information more accessible, especially for individuals who may have difficulty reading or processing complex designs.

In contrast, using multiple typefaces can lead to confusion and can detract from the primary message, making the content less engaging and harder to read. Therefore, adhering to the practice of utilizing one typeface for main text is effective in achieving both aesthetic appeal and functional clarity in communication.
