title: Matplotlib and latex beamer: Correct size
body: <p>There were several questions asked about the integration of matplotlib/Python and latex, but I couldn't find the following:</p>
  
  <p>When I include the <code>savefig()</code> created pdf files in latex, I always to</p>
  
  <pre><code>includegraphics[scale=0.5]{myFile.pdf}
  </code></pre>
  
  <p>And the scale is usually around <code>0.4</code> or <code>0.5</code>. Given that I'm creating A5 beamer slides, what is the correct way to generate pdf files in the correct size for that, such that I don't need to specify that in latex? </p>
  
  <p><em>Note that these are not full-size image-only beamer slides, it needs to be somewhat smaller to allow header,footer and caption.</em></p>
