@defvar face-font-rescale-alist
|

This variable specifies scaling for certain faces. Its value should
|
||||
be a list of elements of the form
|
||||
|
||||
@example
|
||||
(@var{fontname-regexp} . @var{scale-factor})
|
||||
@end example
|
||||
|
||||
If @var{fontname-regexp} matches the font name that is about to be
|
||||
used, this says to choose a larger similar font according to the
|
||||
factor @var{scale-factor}. You would use this feature to normalize
|
||||
the font size if certain fonts are bigger or smaller than their
|
||||
nominal heights and widths would suggest.
