title: LATEX paper size
body: <p>I can't get paper size working with a custom width and height in cm. DVI and even PDF then when they are generated are US Letter.</p>
  
  <pre><code>\documentclass[10pt]{book}
  \usepackage[width=5cm,height=20cm]{geometry}
  \usepackage{lipsum} 
  
  \begin{document}
  
      \title{Some title} 
      \author{Some author} 
      \maketitle 
  
      \lipsum[1-10]
  
  \end{document}
  </code></pre>
  
  <p>I could use but I cant find a way to make it in cm. The result I wanted was x by y in cm PDF or dvi file.</p>
  
  <pre><code>\usepackage[a5paper]{geometry}
  </code></pre>
  
  <p>Thnx in advance folks :)</p>
