[OS X TeX] pdftex paper size

[André Bellaïche]

How can one order to Pdftex/LaTeX to output PDF files with a4 page  
size ?

I am using tetex + TeXShop, and I have selected the a4 option when  
installing the TeX i-package (expert installation). I didn't notice  
until now, but I have got PDF files of size 200,1 x 284,7 mm, or  
205,0 x 265,3 mm, or 194 x 251,2 mm, and no a4.

I didn't use the geometry package, nor am I willing to use it for the  
present purpose. I only want to have a4 as a default.

Thanks for any help,
