Which typefaces are more legible: Serif or Sans Serif?
A Serif typeface is a type of font widely used in traditional media such as newspapers and books. The main difference between Serif and Sans Serif is that Serif fonts have additional details on the edges of the font strokes. The best example of a Serif font is Times new Roman. Serif fonts are also known as Roman.
In the other hand, Sans Serif are, literally, fonts without Serif (Sans means "without" in french). Sans Serif typefaces are also known as Grotesque or Gothic. Good examples of Sans Serif fonts are Arial and Calibri.
