My author list consumes several lines. I would like to reduce the spacing between lines, between the authors and their affiliations, and between their affiliations. I attempted to use the setspace package with the command \setstretch, but this only seems to work in the case where the stretch factor is >1, so I can't figure out how to compress my authblk with this method.

How can the spacings be modified?

My MWE for this author block is here:

% arara: pdflatex
\documentclass[10pt,twocolumn]{article}
\usepackage[margin=0.5in]{geometry}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{amstext}
\usepackage{amssymb}
\usepackage{multirow}
\usepackage{amsmath,amssymb}
\usepackage{verbatim}
\usepackage{authblk}
\usepackage{setspace}
\renewcommand{\familydefault}{\sfdefault}
\usepackage{helvet}

\begin{document}
\large

\vspace{8 pt}
\setstretch{0.1}

\end{document}

Thanks!

    \scriptsize doesn't make the authors smaller, in case that's what you are trying to do with it. – Ulrike Fischer Apr 23 at 10:34
  • That is what I was trying to do with it, so that is a separate problem. The problem that I was trying to illustrate was that \setstretch{<stretch_factor>} only seems to change the spacing of the author block if <stretch_factor> is > 1. – Canaryyellow Apr 23 at 17:01
  • I removed \scriptsize from the example to assist with clarity. Thanks. – Canaryyellow Apr 23 at 17:07

Changing the \baselineskip :

\usepackage{amstext}
\usepackage{amssymb}
\usepackage{multirow}
\usepackage{amsmath,amssymb}
\usepackage{verbatim}
\usepackage{authblk}
\usepackage{setspace}
\renewcommand{\familydefault}{\sfdefault}
\usepackage{helvet}

\makeatletter
\def\@maketitle{%
  \newpage
  \null
  \vskip 2em%
  \begin{center}%
  \let \footnote \thanks
    {\LARGE \@title \par}%
    \vskip 1.5em%
    {\large
      \lineskip .5em%
      \begin{tabular}[t]{c}%
        \baselineskip=12pt
        \@author
      \end{tabular}\par}%
    \vskip 1em%
    {\large \@date}%
  \end{center}%
  \par
  \vskip 1.5em}
\makeatother

  • Thanks, it does exactly what I wanted. Can you explain how it works? It looks like you redefine maketitle, but why do you need an @ for the redefinition. Why are you using \newpage? Which page is new? Why the call to \null? Why do you have so many % symbols. What does the tabular environment allow you to achieve? Sorry about the basic questions, I'm new to this. Your answer is great. – Canaryyellow Apr 26 at 19:31
