Constant Content

My first submission was rejected because of formatting, specifically inappropriate font type and size. I've figured out how to change the text font but still not the size, though. My size options only go from 1 to 6; there is no 12 point font. Am i missing something? Thanks!

I hope this question hasn't been answered as nauseam, but I just submitted my first article here on Constant Content and am terribly confused about the different pricing options. Would anyone mind elaborating? Thanks!
