Strangely when I change the font size to 12pt to (for example) 18pt the font size decrease instead of increasing...any help?

Thank you very much!

Hi and welcome,

the standard LaTeX classes know some basic options to selct the font size, 10pt, 11pt and 12pt. Option 18pt is not defined, and so the default 10pt is used. You get an according warning in the log-file.

If you really want to use a fontsize that large, have a look at KOMA-script, memoir or the extsize classes.

Thank you very much!
