What the font?

In typography, there are two different types of fonts; serif and sans serif. The difference between these two categories is the way the end of the strokes are designed. 

Serif   – Sans Serif

The first word, serif, has details on the ends of some of the strokes, these are the serifs. The sans serif typeface has no details at the end of the strokes. This is especially visible at the bottom of the r, i and f.

Generally, the serif font is used for printed works such as newspapers and books, because they are often considered easier to read in long passages. On websites, the sans serif font is usually used, because it is believed that these are easier to read on a computer screen. This is visible on, for example, Facebook and Twitter.



Here you can see these websites use the sans serif typeface.
