Really large poster in a0poster or other package

Question

I am designing a poster for a conference (first one in many years). I am using a0poster, but the poster allows for two panels, one of which is 4 feet square, the other 4 feet by 2 feet, with a hinge between.

a0poster seems to have a maximum size of 33" by 46". I could make two posters, one a0 and one smaller, but is there a way to make it in one poster?

Answer 1

Beamerposter can handle custom page sizes, at least. Not sure about other classes, but since I already was using beamer for presentations, beamerposter was an easy transition.

Example (72" wide, 48" high):

important bit (lengths in cm by default, may be able to change to more comfortable units):

\usepackage[size=custom,width=182.88,height=121.92,scale=3]{beamerposter} % e.g. for custom size poster

Full example:

\documentclass[final]{beamer} % beamer 3.10: do NOT use option hyperref={pdfpagelabels=false} !
\mode<presentation> {  %% check http://www-i6.informatik.rwth-aachen.de/~dreuw/latexbeamerposter.php for examples
  \usetheme{Berlin}    %% you should define your own theme e.g. for big headlines using your own logos
