You are supposed to be able to change the size of things via the commands
\large
\huge
etc. However, they don't seem to work in math mode. The following code
\documentclass{article}
\usepackage{amsmath}
\begin{document}
${\footnotesize Text\text{Text}}$\\
${\scriptsize Text\text{Text}}$\\
${\normalsize Text\text{Text}}$\\
${\large Text\text{Text}}$\\
${\Large Text\text{Text}}$\\
${\LARGE Text\text{Text}}$\\
${\huge Text\text{Text}}$\\
${\Huge Text\text{Text}}$\\
\end{document}
produces this:
While regular text is resized accordingly, things directly in math mode don't change.
Edit: I don't just want do change the size of a complete formula (which is solved by the answer from Rmano) but of singular symbols inside the formula (e.g. an integral sign inside an underset) which seems to only be possible with the \scriptscriptstyle
, \scriptstyle
, \displaystyle
and \textstyle
command. Since there are only these four, how can you change it to different sizes (especially larger ones)?
\dispalystyle
,textstyle
,\scriptstyle
and\scriptscriptstyle
. You also can leave math mode,and , in a group, change the fontsize and reenter mathmode.\tiny
,\scriptsize
,\footnotesize
,\small
,\normalsize
,\large
,\Large
,\LARGE
,\huge
, and\Huge
are for text mode; they are NOT to be used in math mode. For math mode, use\scriptscriptstyle
(akin to\tiny
) and\scriptstyle
(akin to\scriptsize
).
