[Tex/LaTex] Change font size relative to current font size

fontsize

For some small macros I'm writing I would need to change the font size relative to the font size of the text that surrounds to macro later on.
I only know how to change the font size for the whole document (documentclass/fontspec), or for some text, but only relative to the default font size for the document (\Large, \small).

What I was thinking of was something like:

\newcommand*\mycommand{\smaller ipsum}
\Large lorem \mycommand
\small lorem \mycommand

If I use \Large, \small etc in the command itself, it will not care about the font size of the surrounding text but set the font size relative to the default font size. I would want it to be e.g. 1.2 times smaller than \Large or \small, depending on where it is used.

Have a look at the relsize package. Package description:

The basic command of the package is \relsize, whose argument is a number of \magsteps to change size; from this are defined commands \larger, \smaller, \textlarger, etc.

default value for option 'scaled' is '.9. You can set scale to explicit value, e.g., \usepackage[scaled=.7]{beramono}

I show your original, followed by two alternatives. The first scales the summation to 20% of the original size. The second scales the 3 to 500% of the original size. The \scaleobj command is part of the scalerel package. It is similar to the \scalebox command of the graphicx package, except that it defaults to math mode, and takes the current math style into account.

\pdfoutput=0
\documentclass[fleqn]{article}
\usepackage[T2A]{fontenc}
\usepackage[cp1251]{inputenc}
\usepackage{concmath}
\usepackage{amsmath}
\usepackage{scalerel}

\begin{document}
\thispagestyle{empty}

\begin{displaymath}
3^{\displaystyle \sum_{n=0}^{\infty}\frac{(-1)^n}{2^n}}
\end{displaymath}

\begin{displaymath}
3^{\scaleobj{.2}{\displaystyle \sum_{n=0}^{\infty}\frac{(-1)^n}{2^n}}}
\end{displaymath}

\begin{displaymath}
\scaleobj{5}{3}^{\displaystyle \sum_{n=0}^{\infty}\frac{(-1)^n}{2^n}}
\end{displaymath}

\end{document}
