Personally, I simply change the size of the device I'm plotting on. When I 
plot on a large device, the fonts will be relatively smaller, and vice 
versa. This is what I do when including graphics in PDF files (papers, 
slides, reports, etc.).

For fine control, you can set the arguments of the labeling function 
employed. ?strucplot shows that the default is ?labeling_border which has 
several arguments. For example you can set the graphical parameters of the 
labels (gp_labels) or the graphical parameters of the variable names 
(gp_varnames). Both arguments take ?gpar lists ("grid" graphical 
parameters). For example you may do

   mosaic(UCBAdmissions)

and

   mosaic(UCBAdmissions, labeling_args = list(
     gp_labels = gpar(fontsize = 12, fontface = 3),
     gp_varnames = gpar(fontsize = 16, fontface = 2)
   ))

etc.

Hope that helps,
