Serifs are the small ticks at the end of letters. Serif fonts use these ticks, and in printed media, can guide the reader’s eye from one letter to the next. I believe that serif fonts in screen media are too busy, and so these fonts should be reserved for print. The classic example of a serif font is Times New Roman.
Sans-serif fonts lack the small ticks at the end of the letters. Traditionally, in print, these fonts were reserved for headlines. In screen media, however, I believe these fonts look cleaner and are more readable. Sans-serif fonts can be crudely broken down into the following sub-categories.:
^ Name ^ Description ^ Examples ^ ^ Grotesque | Traditional sans-serif fonts. Straight with low variation of width. | Grotesque | ^ Neo-grotesque / Transitional | A more modern take on grotesque | Arial, Helvetica, Univers | ^ Humanist | A more moden class of san-serif, where letters have more varied widths | Johnson, Gill Sanes, Frutiger, Myriad, Segoe UI, Optima | ^ Geometric | Based on geometic shapes - lines and curves with first order continuity | Avant Garde, Century Gothic, Futura, Gotham, or Spartan |
