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.

Problem is, I can only make the text bigger, not the circle in the radiobutton. 

```
<RadioButton  VerticalAlignment="Center" x:Name="rbtnContainers" Click="SetContainers" FontSize="18">Containers</RadioButton>

```

Using height doesn't work either. It makes the radiobutton bigger, but the circle remains the same.

Any hint or answer is appreciated.
