The vast majority of Emacs refcards is using A4 layout, which I
think is fine for the Org refcard.

Attached are the current version and the one with the new layout. 
I do like the current version better, even for the (1/2) and (2/2)
parts, that I find missing.

José Miguel, what are you exactly trying to fix?  Is it about 
adding flexibility to the layout so that, if needed, one can use
the US letter format?
