List of Figure/Table : Full justify caption

Question

How can I fully justify list of figure/table like the image below ?

I believe it has something to do with tocloft configuration, but I cant find relevant things related to justify.

Answer 1

You are correct about the tocloft package. However, it has nothing to do with “justify”: It’s all about left-indents and right-margins.

\documentclass{article}
\usepackage{amsmath}
\numberwithin{figure}{section}
\usepackage{newtxtext}
\usepackage{tocloft}
\cftsetrmarg{0pt}% <- Set right margin to zero
\renewcommand\cftfigpresnum{\figurename~}% <- Prepend `Figure' in front of number
\renewcommand\cftfigaftersnum{:}% <- Append `:' behind number
\renewcommand\cftfigaftersnumb{\hspace{5em}}% <- Add enough space to start caption text
\cftsetindents{figure}{0pt}{0pt}% <- Set left indents to zero
\usepackage{blindtext}
\begin{document}
\listoffigures
\section{Blah}
\begin{figure}[!hb]
No thing to see here.
\caption{\blindtext}
\end{figure}
\begin{figure}[!hb]
No thing to see here.
\caption[Short caption title]{\blindtext}
\end{figure}
\blindtext
\end{document}

But why would you want to do this? The first caption in the LoF looks so crowded and you should keep the LoF (and ToC, LoT, etc) clean and concise. Just use short caption title as in the second caption and you don’t need to change many things. I intentionally leave out the customization of the LoT as well as that of the ToC, and strongly encourage you to use short titles.
