# How To fix these Warning Overfull \hbox (202.24913pt too wide)?

I have this warning a lot on file: Overfull \hbox (202.24913pt too wide) in paragraph at lines 7--8 Here is an example

   \documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{positioning,calc,arrows.meta}
\begin{document}
\begin{enumerate}

\item The distributor sends a transaction to the blockchain containing
($\sigma_{agg} || PK_{V_{1}},\ldots,PK_{V_{m}}||C^{M_\theta}_{PK_{V_1}},\ldots, C^{M_\theta}_{PK_{V_m}}|| k_{1},\ldots, k_{m})$ where $m$ is the number
of vehicles that received the update.

\end{enumerate}
\end{document}

• Is your actual document a standalone or did you use it only for the MWE? Nov 14 '18 at 8:37
• Can you go back to your previous questions and look if the answers solve your problems and accept them, if they do? Nov 14 '18 at 9:33

Two possible solutions assuming you use article and not standalone. The first one writes the math expression as a non numbered equation and the second inserts a manual break in math.

I prefer the first one.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,calc,arrows.meta}
\begin{document}
\begin{enumerate}

\item The distributor sends a transaction to the blockchain containing
$(\sigma_{agg} || PK_{V_{1}},\ldots,PK_{V_{m}}||C^{M_\theta}_{PK_{V_1}},\ldots, C^{M_\theta}_{PK_{V_m}}|| k_{1},\ldots, k_{m})$ where $m$ is the number
of vehicles that received the update.

\item The distributor sends a transaction to the blockchain containing
$(\sigma_{agg} ||$ $PK_{V_{1}},\ldots,PK_{V_{m}}||C^{M_\theta}_{PK_{V_1}},\ldots, C^{M_\theta}_{PK_{V_m}}|| k_{1},\ldots, k_{m})$ where $m$ is the number
of vehicles that received the update.

\end{enumerate}
\end{document}
