Hi,

I'm writing a document. my code is:

\documentclass[a4paper,10pt]{book}
\usepackage[utf8x]{inputenc}
\usepackage[italian]{babel}

\title{TESI FINASS}
\author{Ivan Granito}

I need to enlarge the font size but if I put 14 in the first command line the character in the pdf is always of size 10 ...
