# Changing the text size is not working

I am an eighth grader that needs some help. I am a noob at anything TeX or LaTeX, and am just starting out. I am using USBTeX, just in case that matters.

I cannot seem to change the text size in the \documentclass[]{} thingy in the beginning of the document. My TeX editor sets it to 10pt at default, but when I try to change it to something different, nothing happens. Any ideas?

Have you tried \documentclass[11pt]{...} or \documentclass[12pt]{...}? There are only certain sizes supported by certain document classes. What document class are you using? Also, what size do you want it to change to? Do you receive any errors/warnings when you compile? If so, what do they say? –  Werner May 9 '12 at 19:08
Alright, so I am using article, this is what my "mentor" told me to use. And I think the error is something like "font size not used" or something similar... –  fr00ty_l00ps May 9 '12 at 19:20
A big welcome to TeX.SX! If you want a better range of font size options, with things like \Large suitably adjusted, you might want to try memoir. Something like \documentclass[9pt,article]{memoir}. It has lots more, too, and might be a good path for investing your learning time. –  Brent.Longborough May 10 '12 at 12:36
Okay, gotcha. Thanks!!! –  fr00ty_l00ps May 30 '12 at 14:53
