In desktop publishing, when are serif fonts typically used?

Serif fonts are typically used for body text in desktop publishing due to their enhanced readability in longer passages. The small lines or decorative features at the ends of the strokes in serif fonts help guide the flow of the text, making it easier for the reader to follow along. This characteristic is particularly beneficial in print materials where text is often dense, allowing the eyes to move efficiently from one letter to the next.

In contrast, sans-serif fonts are commonly chosen for headlines and subheadings because they provide a cleaner and more modern aesthetic, often standing out more effectively in those contexts. Thus, the use of serif fonts for body text emphasizes their purpose in facilitating reading comfort and clarity in substantial written content.
