This feature can't import fonts from your computer - it can only use fonts on our server. (Know of a font you'd like added - that's free for commerical use? Email me and I'll see if I can help).
Font size: pts.
Worksheet Genius will use this font size as a starting point. If it can't squeeze in the text (because the questions won't all fit on the page), then a smaller font size will be used. At the moment, a standard font size is used for the header and footer.
