title: From Markdown to PDF: how to change the font-size with Pandoc?
body: <p>I'm converting some Markdown files into PDF using Pandoc like this:</p>
  
  <pre><code>pandoc input.md -V geometry:margin=1in -o output.pdf 
  </code></pre>
  
  <p>By default, the font-size is quite small in the pdf. I'd like to make all the fonts bigger (title, sub title, text, etc.). How can I do that? </p>
