PDF (from page) - is there a way to change font size?

I’ve been asked if it’s possible to make the pdf text bigger for the output of one of our forms. It seems I can alter the size of the text of the answers between small > medium > large but that’s about it. Has anyone found away around this?

Thanks,

Could you put a custom class in the late style sheet to define the font and size you want to use, then apply the custom CSS class to the element on the page? (I’m assuming all classes on the page will be reflected in the PDF)
