Unix X-System also has these named fonts, so that you can be pretty sure that your user will at least have these fonts. Examples can be found on this page . When selecting the font, bear in mind what purpose it is going to be used for. If you answer these questions you are more than halfway towards selecting the correct font. Bear these points in mind.
Titles Remember what purpose a title serves.
It is there to draw attention or announce a section, to aid the reader in his navigation around a page, and in scrolled media it may assist in easy scrolling. With the latter in mind try and make sure that every screen has at least one title, or subtitle, which will result in a frequency of titles much greater than that required for the printed page. Almost any font can be used as a title as long as it fits in with the over all theme of the page and is not grossly incompatible with the reading font. A traditional combination, used in these pages is 'Arial' for the titles, and 'Times New Roman' for the text. The prime consideration here is that the typography should not call attention to itself, but rather show off the content.
