# Changing the dimensions of a poster

I want to change the dimensions of the following A1 poster to be 22 x 28 inch. I do not want only to "stretch" it to manually fit the new dimensions but to have a new arrangement of the text according to the new dimensions size. I tried many different options but none of them:

1. Change the dimensions into non-proportional new dimensions (A1 is 23.4 X 33.1 and 22/23.4 not equal to 28/33.1)- so geometry doesn't fit.

2. Work well with xclolr, itemize and the other packages in the code.

Here is the code:

\documentclass[a1,portrait]{a0poster}
\usepackage{multicol}
\columnsep=100pt
\columnseprule=3pt
\usepackage{pdfposter}
\usepackage[svgnames]{xcolor}

\usepackage{times}
\usepackage{graphicx}
\graphicspath{{figures/}}
\usepackage{booktabs}
\usepackage[font=small,labelfont=bf]{caption}
\usepackage{amsfonts, amsmath, amsthm, amssymb}
\usepackage{wrapfig}

\begin{document}

\begin{minipage}[b]{0.75\linewidth}
\Huge \color{NavyBlue} \textbf{Title} \color{Black}\\
\huge\textit{Title}\\[2cm]
\huge \textbf{Name}\\[0.5cm]
\huge University\\[0.4cm]
\Large \texttt{email} \\
\end{minipage}

\begin{minipage}[b]{0.25\linewidth}
\includegraphics[width=20cm]{logo.png}\\
\end{minipage}

\vspace{1cm}

\begin{multicols}{3}

\color{Navy}

\section*{Research Question}

\begin{itemize}

\item blah blah

\end{itemize}

\section*{In This Paper}

\begin{itemize}

\item bla bla
\end{itemize}

\end{multicols}
\end{document}

• To explain my dificulty, if I add the following lines in the begining of the code: \documentclass[portrait,a1]{a0poster} \setlength{\paperwidth}{22in} \setlength{\paperheight}{28in} It is just stretch the paper, so part of the text disappear – Muly Sep 11 '17 at 21:48
• Are you aware of the geometry package? If not, take a look. – Dr. Manuel Kuehner Sep 11 '17 at 22:42
• Use the option showframe=true to help to understand the effects of the different parameters. – Dr. Manuel Kuehner Sep 11 '17 at 22:43
• Is your problem solved? If yes, consider accepting the best answer. – Dr. Manuel Kuehner Sep 13 '17 at 15:47

It is not enough to change the paperwidth, you also need to reset the textwidth. With geometry it works fine:

\documentclass[a1,portrait]{a0poster}

\usepackage{multicol}
\columnsep=100pt
\columnseprule=3pt
%\usepackage{pdfposter}
\usepackage[svgnames]{xcolor}

\usepackage{times}
\usepackage{graphicx}
\graphicspath{{figures/}}
\usepackage{booktabs}
\usepackage[font=small,labelfont=bf]{caption}
\usepackage{amsfonts, amsmath, amsthm, amssymb}
\usepackage{wrapfig,lipsum}
\usepackage{geometry}
\geometry{paperwidth=22in,paperheight=28in,margin=2cm}

\begin{document}
\lipsum[1]
\begin{minipage}[b]{0.75\linewidth}
\Huge \color{NavyBlue} \textbf{Title} \color{Black}\\
\huge\textit{Title}\\[2cm]
\huge \textbf{Name}\\[0.5cm]
\huge University\\[0.4cm]
\Large \texttt{email} \\
\end{minipage}

\begin{minipage}[b]{0.25\linewidth}
\includegraphics[width=20cm]{example-image}\\
\end{minipage}

\vspace{1cm}

\begin{multicols}{3}

\color{Navy}

\section*{Research Question}

\begin{itemize}

\item blah blah

\end{itemize}

\section*{In This Paper}

\begin{itemize}

\item bla bla
\end{itemize}

\end{multicols}
\end{document}


Be aware that a0poster inserts postscript specials which aren't really suitable for pdflatex. Imho a saner solution would be to use article.cls, set the page size with geometry and copy the few needed lines for the font sizes from a0poster.cls and a0size.sty.

• Thanks! a bit too late (I already printed the A1 size poster) but it works... – Muly Sep 14 '17 at 17:32
