[Tex/LaTex] ny second way to change font size!

Question

I am using a specific latex template for my thesis. But I cannot change the font size, that I want to have 14pt. Here is my code:

\documentclass[MACS,english]{gucthesis}
\usepackage{geometry}
\geometry{a4paper}
\addtolength{\topmargin}{2 cm}
\addtolength{\textheight}{2 cm}
\usepackage{times}
\usepackage[utf8]{inputenc}
\usepackage[pdftex]{graphicx}
\usepackage[pdftex]{hyperref}   
\usepackage{color} 
\usepackage{url}
\usepackage{afterpage}
\begin{document}
... ... 
\end{document} 

I know \documentclass[14pt]{article} works, and that is the common method for this problem, but as I said I am using very specific templates, it is not working in my case. Is there any other way I can control over the font size.

Thanks.

You can use fontsize selectfont :

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[frenchb]{babel}

\begin{document}

Coucou
\fontsize{14pt}{14pt}\selectfont
Coucou
\fontsize{28pt}{28pt}\selectfont
Coucou

\end{document}
