# Overfull \hbox (15.0pt too wide)

I have multiple tables which look like this:

\begin{tabularx}{\textwidth}{|l|X|l|}
\hline
\textbf{ID} & \textbf{Description} \\ \hline
336858 & The description \\ \hline
\end{tabularx}

and I get for each one the warning:

Overfull \hbox (15.0pt too wide) in paragraph at lines X -- Y[][]

As I understand this mean something in my table don't use enough space. Or according my search when I use explicit spacing.

And thats the part I don't understand, because the Idea of {|l|X|l|} is that it use 100% width of the Document. And the output is expected.

What did I miss or misunderstand? Why did I get this warning?

minimal example

\documentclass[a4paper,10pt]{article}

\usepackage{tabularx}

\usepackage[utf8]{inputenc}
\usepackage[top=7em, bottom=4em, left=5em, right=5em]{geometry}
\usepackage{xcolor,colortbl}

\usepackage{hyperref}
\hypersetup{
citecolor=black,
filecolor=black,
urlcolor=black
}

\setcounter{section}{-1}

\title{Test}
\author{test author}

\begin{document}

\maketitle
\tableofcontents

\begin{tabularx}{\textwidth}{|l|X|l|}
\hline
\textbf{ID} & \textbf{Description} \\ \hline
336858 & The description \\ \hline
\end{tabularx}

\end{document}

I use pdflatex to build.

• First of all it is a warning, not an error. Secondly, always provide a minimal example we can copy and paste. We do not know your preamble or other packages. – daleif Aug 21 '14 at 12:44
• @daleif thanks for pointing these things out – Sir l33tname Aug 21 '14 at 12:57
• (1) you need to compile a few times for tabularx to stabilize. (2) When I do that the only thing I get is an overfull \hbox of 15pt which is exactly the paragraph indentation. Try adding \noindent or place the table inside the center env – daleif Aug 21 '14 at 12:57
• @daleif Adding \noindent seems to be the correct answer. Would you care to make one? :) – yo' Aug 21 '14 at 12:58
• @Sirl33tname Your example isn't an example of the problem described in the question: It does not generate the underfull box warning in the title. It generates an unrelated overfull box warning (addressed by daleif's answer) . Please either edit the example to match the question or edit the question to match the example. – David Carlisle Aug 21 '14 at 13:15

2. In my system (TeX Live 2014), then the only warning I get is a overfull \hbox (15.0pt too wide). 15pt is the standard size of the paragraph indentation. So you may want to use

\noindent
\begin{tabularx}...

or

\begin{center}
\begin{tabularx}....
...
\end{tabularx}
\end{center}

\noindent command is the correct answer. Overfull \hbox (15.0pt too wide) is a warning only. After applying \noindent command before starting \begin{tabularx} command your code runs perfectly well. I got zero error, zero warnings and zero bad boxes. However, I am working with MikTex 2.9 in windows 8.
