By default, Emacs displays text in the font named `9x15', which makes each character nine pixels wide and fifteen pixels high. You can specify a different font on your command line through the option `-fn name'.
Under X, each font has a long name which consists of eleven words or numbers, separated by dashes. Some fonts also have shorter nicknames---`9x15' is such a nickname. You can use either kind of name. You can use wildcard patterns for the font name; then Emacs lets X choose one of the fonts that match the pattern. Here is an example, which happens to specify the font whose nickname is `6x13':
emacs -fn "-misc-fixed-medium-r-semicondensed--13-*-*-*-c-60-iso8859-1" &
You can also specify the font in your `.Xdefaults' file:
A long font name has the following form:
Use only fixed-width fonts--that is, fonts in which all characters
have the same width; Emacs cannot yet handle display properly for
variable-width fonts. Any font with `m' or `c' in the
spacing field of the long name is a fixed-width font. Here's how
to use the
xlsfonts program to list all the fixed-width fonts
available on your system:
xlsfonts -fn '*x*' xlsfonts -fn '*-*-*-*-*-*-*-*-*-*-*-m*' xlsfonts -fn '*-*-*-*-*-*-*-*-*-*-*-c*'
To see what a particular font looks like, use the
xfd -fn 6x13
displays the entire font `6x13'.
While running Emacs, you can set the font of the current frame (see section Setting Frame Parameters) or for a specific kind of text (see section Using Multiple Typefaces).
