PerfectForms only offers 4 standard fonts, but you can use any font as long as your user's machines have it. When the form opens use a set property behavior object. Choose the input field, in the drop-down choose “Font”. Under Text or number write “font name" (arial for example), 12 (the number represents the font size). Keep in mind that this will only work if the user’s machine has that font. I think the basics like Arial, and century gothic are pretty common.
