Changing the font size [closed]

When I change my first line from

\documentclass{report}


to

\documentclass{report}[12pt]


the font size of the resulting pdf doesn't increase. I am using pdflatex to compile tex to pdf.

• Welcome to TeX.SX! You have the order wrong, it should be \documentclass[12pt]{report}. – Torbjørn T. Apr 10 '14 at 16:26
