chaptersfontsizememoir
How would one go about this? Below my MWE. I should note that \HUGE appears no different from \Huge, but I decided to use it anyway as it should be the largest option.
\documentclass[12pt]{memoir}
\input{preface}
\usepackage{egothic}%
\makeatletter
\makechapterstyle{ene}{%
\renewcommand*{\chapnumfont}{\chapnamefont}%
\renewcommand*{\chaptitlefont}{\hfill\egothfamily\HUGE}%
}
\chapterstyle{ene}
\begin{document}
\chapter*{1}
This is the first chapter.
\end{document}
You can use the Memoir document class. It provides two things that are relevant to your question:
The standard LaTeX document classes only allow you to choose 10pt, 11pt or 12point as the "base" font size for your document. Memoir provides many more choices: 9pt, 10pt, 11pt, 12pt, 14pt, 17pt, 20pt, 25pt, 30pt, 36pt, 48pt and 60pt. Since all font size declarations are affected by the base font size, using a bigger base font size will make \Huge render in a bigger font.
For when it absolutely has to be bigger than \Huge, crank it to 11 with \HUGE.
It's the same as the standard classes, you can go
\chapter[short]{long}
and the short form is used in headers and table of contents.

You're free to create a new macro called, say,
\YUGE(sorry, I couldn't resist!), asor, if you want to go overboard completely, as
and then use
\YUGEinside the definition of\chaptitlefont.
