title: Sizing the radiobutton
body: <p>I have some radiobuttons in an app that works with touch. 
  Because the end-user can have thick fingers, I want to make the circle and text int he radiobutton bigger.</p>
  
  <p>Problem is, I can only make the text bigger, not the circle in the radiobutton. </p>
  
  <pre><code>&lt;RadioButton  VerticalAlignment="Center" x:Name="rbtnContainers" Click="SetContainers" FontSize="18"&gt;Containers&lt;/RadioButton&gt;
  </code></pre>
  
  <p>Using height doesn't work either. It makes the radiobutton bigger, but the circle remains the same.</p>
  
  <p>Any hint or answer is appreciated.</p>
