Math & Science ⇒ newcommand superscript

[dax42]

Hi there,

I would like to define a new command to make sub- and superscripts easier. I found this online, which works well:

\newcommand{\super}[1]{\ensuremath{^{\textnormal{#1}}}}
\newcommand{\sub}[1]{\ensuremath{_{\textnormal{#1}}}}

However, my normal text is 11pt and thus the sub/superscripted letters are too big for my taste. How can I define this command so it uses, say, 8pt?

Thanks!

Hi,

insert an appropriate font size command. To match the size LaTeX uses for subscripts choose \scriptsize, like

Code: Select all

1
\newcommand{\super}[1]{\ensuremath{^{\textnormal{\scriptsize #1}}}}

Btw. \textnormal prevents the italic shape which is normally used in math sub-/superscripts.

Sweet, thanks!

\textnormal prevents the italic shape which is normally used in math sub-/superscripts.

Which is exactly why I'm using it...

@dax42:
Morten Høgholm once came up with an elegant solution on a Danish mailing list:

I hope this is (somewhat) what you are looking for.
