[Tex/LaTex] Fonts larger than \Huge

fontsize

How can I make text that is larger than the size of the output of {\Huge ...}?

I would like to be able to make text arbitrarily large (even if that is done by some suboptimal scaling routine).

Best Answer

You can use the Memoir document class. It provides two things that are relevant to your question:

More Base Font Sizes

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.

The \HUGE Font Size

For when it absolutely has to be bigger than \Huge, crank it to 11 with \HUGE.

itemize symbols have font size hardcoded in definition (look at beamerthemedefault.sty or beamerbaseauxtemplates.sty).

% Itemize items, circle

\defbeamertemplate{itemize item}{circle}{\small\raise0.5pt\hbox{\textbullet}}
\defbeamertemplate{itemize subitem}{circle}{\footnotesize\raise0.5pt\hbox{\textbullet}}
\defbeamertemplate{itemize subsubitem}{circle}{\footnotesize\raise0.5pt\hbox{\textbullet}}

Section 16.3 "Changing the Templates Used for Different Elements of a Presentation" form beamer manual explain how to change it. It seems that would be possible to define a template with an option for font size. I don't know how to do it but a fast solution could be redeclare itemize symbols with new hardcoded size, something like

\documentclass{beamer}

\begin{document}    
\begin{frame}[t]{Frame title}
  \begin{itemize}
  \item First item
  \item Second item
  \end{itemize}
\bigskip
{\setbeamertemplate{itemize item}{\small\raise1.25pt\hbox{\donotcoloroutermaths$\blaktriangleright$}}
  \begin{itemize}
  \item Second first item
  \item Second second item
  \end{itemize}
}
\bigskip
  \begin{itemize}
  \item Third first item
  \item Third second item
  \end{itemize}
\end{frame}
\end{document}

EDIT: Changing balls for Madrid Theme.

Madrid Theme (beamerthemeMadrid.sty) uses \useinnertheme[shadow]{rounded} which declares \setbeamertemplate{items}[ball]. So we need to look for ball in beamerbaseauxtemplates.sty. To do it short, in this file some 'spheres' are defined and used. You can make your own definition,

\documentclass{beamer}
\usetheme{Madrid}

\makeatletter
\pgfdeclareradialshading[bg,parent.bg]{mysphere}{\pgfpoint{0.15cm}{0.15cm}}%
{color(0cm)=(bg!15);
 color(0.15cm)=(bg!75);
 color(0.3cm)=(bg!70!black);
 color(0.301cm)=(parent.bg)}

\defbeamertemplate{itemize item}{myball}%
{\raise-0.2cm\beamer@usesphere{item projected}{mysphere}}
\makeatother

\begin{document}    
\begin{frame}[t]{Frame title}
  \begin{itemize}
   \item First item
   \begin{itemize}
     \item first subitem
     \item second subitem
   \end{itemize}
   \item Second item
  \end{itemize}
  \bigskip
{\setbeamertemplate{itemize item}[myball]
  \begin{itemize}
   \item Third first item
   \item Third second item
   \end{itemize}
}
\end{frame}
\end{document}

The result is

I think sphere sizes are related with font size because they are declared using ex units but I'm not able to change its size with just a fontsize declaration. May be somebody else can help us.

[Tex/LaTex] How to make math font huge

The graphicx package provides the command \resizebox. The lscape package provides the landscape environment.

Together they could be used as follows:

\documentclass{article}
\usepackage[paper=a4paper]{geometry}
\usepackage{graphicx}
\usepackage{lscape}

\begin{document}
\pagestyle{empty}

\begin{landscape}
\begin{center}
 \resizebox{20cm}{!}{$e^{i\pi}=-1$}
\end{center}
\end{landscape}

\end{document}

Note that the \resizebox takes arguments \resizebox{width}{height}. In the above I have used {!} for the height to ensure that the aspect ratio remains true- otherwise you might get ugly stretched boxes.
