Page shrinking or scaling

Hi y'all,

 

Is there a way to shrink the page size in Docbook without having to 
reformat the doc going to PDF (FOP).

 

My users would like to have a "half size" manual to travel with instead of 
a regular US Letter size page. I guess I could to this at the printers, but it 
would be nice if I could do it at the office.

 

I tried adjusting the page.height and .width but that just messed things up 
because the fonts were still the same size as were the images.

 

Any ideas?

 

Regards,

Dean Nelson
