How to reduce space between image and its caption?

Question

I m importing one image in latex document. But caption has bigger font than my normal text on page.

\documentclass{article}
\usepackage{graphicx}

\begin{document}

  Some text...

  \begin{figure}[htb]
  \begin{center}
  \includegraphics[height=1in,width=1in,angle=-90]{foo}
  \caption{This is a figure.}

How to reduce the font size of caption and space between caption and image?

Answer 1

You can do it with caption package. The space between the caption and the figure is called skip (default is 10pt).

\documentclass{article}
\usepackage[demo]{graphicx} %% Remove [demo] in your file
%\usepackage{caption}
%\captionsetup[table]{font=small,skip=0pt}     %% Adjust here
%or equivalently 
\usepackage[font=small,skip=0pt]{caption}

\begin{document}

  Some text...

  \begin{figure}[htb]
  \begin{center}
  \includegraphics[height=1in,width=1in,angle=-90]{foo}
  \caption{This is a figure.}
  \end{center}
  \end{figure}

   More text...

  \begin{table}[htb]
  \centering
  \caption{This is a table.}
  \begin{tabular}{|c|c|}
    \hline
    % after \\: \hline or \cline{col1-col2} \cline{col3-col4} ...
    1 & 2 \\
    4 & 7 \\
    \hline
  \end{tabular}
  \end{table}

     More text...

  \end{document}

Please note that \captionsetup{font=small,skip=0pt} affects both tables and figures. If you want it separately, you may use:

 \captionsetup[table]{font=small,skip=0pt}

for tables only or

\captionsetup[figure]{font=small,skip=0pt}

for figures only.

Answer 2

A brute force \vspace{1pt} just before the caption, inside any figure, also works if one wants to change spacings locally.

Answer 3

For locally change the caption position you can also use a negative value on the setting. For example, when the figure has larger white part, e.g use \vspace{-1cm}, instead of changing the figure itself.
