So I am creating a title page for my thesis, I am using Classicthesis, and I am using this title page as a draft UNAM thesis title page (portada tesis UNAM). The issue I am having is that the titlepage appears very tiny and is not centered I would like that my titlepage fits the whole page.
Here is my titlepage code:
\documentclass[11pt,a4paper,titlepage]{book}
\usepackage[spanish,mexico]{babel}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{xcolor}
\begin{document}
%*******************************************************
% Titlepage
%*******************************************************
\begin{titlepage}
\thispagestyle{empty}
\fbox{
\begin{minipage}[c][0.1\textheight][c]{0.2\textwidth}
\begin{center}
% \includegraphics[width=1.2\textwidth]{gfx/Logo_ITC_cl.pdf}
\end{center}
\end{minipage}
}
\fbox{
\begin{minipage}[c][0.1\textheight][t]{0.65\textwidth}
\begin{center}
{\scshape{TECNOLOGICO NACIONAL DE MEXICO}}
\vspace{.3cm}
\hrule height2.5pt
\vspace{.1cm}
\hrule height1pt
\vspace{.3cm}
{\scshape {INSTITUTO TECNOLOGICO DE CELAYA}}
\end{center}
\end{minipage}
}
\fbox{
\begin{minipage}[c][0.6\textheight][t]{0.2\textwidth}
\begin{center}
\hskip2pt
\vrule width2.5pt height10cm
\hskip1mm
\vrule width1pt height10cm \\
%\includegraphics[width=1.5\textwidth]{gfx/Logo-TecNM.pdf}
\end{center}
\end{minipage}
}
\fbox{
\begin{minipage}[c][0.6\textheight][t]{0.65\textwidth}
\vspace*{1cm}
\begin{center}
{\Large \scshape {\begingroup \color{red}{myTitle}
\endgroup}}
\vspace{2cm}
\makebox[5cm][c]{\huge T \hspace{0.5cm} E \hspace{0.5cm} S \hspace{0.5cm} I \hspace{0.5cm} S } \\[8pt]
QUE PARA OBTENER EL TITULO DE:\\[5pt]
{\large{myDegree}}\\[40pt]
PRESENTA:\\[5pt]
{\large{myName}}
\vspace{1cm}
{TUTOR:\\ \large{{myProf}}}
\vspace{0.5cm}
myTime
\end{center}
\end{minipage}
}
\end{titlepage}
\end{document}
And this is the output
I tried using \resizebox{\textwidth}{!}{content} but this happens:

Any ideas?
John Kormylo solved it in a very acurate way.
Another solution I found is putting every minipage beetwen scalebox{1.2}{content} from the graphicx package, it does the trick but is not as sharp and acurate as John Kormylo's.

adjustboxpackage gives you aadjustboxenvironment which allows you to scale its content, e.g.\begin{adjustbox}{varwidth=\textwidth,width=\textwidth} ... \end{adjustbox}. You could also addheight=\textheight,keepaspectratioif the height is limiting the zoom. – Martin Scharrer Dec 20 '17 at 18:40
