From A4 to A3 (A2, A1, A0)

I've prepared a poster. For the development purposes, the paper size is A4. Now I need to enlarge the paper size. Here is a sequence of the commands which got the things done:

pdftops poster.pdf
psresize -PA4 -pA3
ps2pdf -sPAPERSIZE=a3

Unfortunately, psresize doesn't know A2, A1 and A0 format. Therefore, direct dimension specification is required:

psresize -PA4 -w420mm -h594mm
psresize -PA4 -w594mm -h841mm
psresize -PA4 -w841mm -h1189mm
