How to make \uparrow to be as long as the object left to it? Is there a way like for brackets \right] ? How to make this look nice:
\documentclass[15pt, a4paper]{scrartcl}
\usepackage{amsmath,amssymb,stmaryrd}
\begin{document}
\[ s_R \uparrow \Rightarrow \left( \dfrac{L_A}{L}\right)_{dec.} \uparrow \]
\end{document}
I'm looking for an easy way within the environment [] or align. I hope there is a tikz-free way for achieving this. Thank you 🙂

Try
\left. ... \right\uparrow
If
dec.
is a name you also ought to use_{\textup{dec.}}
do it is not read as three indices and a dot.
