+@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.
