View source for Latex tricks to reduce the number of pages of articles

* Use \vspace{-5mm} after your figures to reduce the spacing between the caption and the rest of the text. Example:
<pre>
\begin{figure}
	\centering
	\includegraphics{figurename}
	\caption{Put your caption here}
	\label{fig:figlabel}
	\vspace{-5mm}
\end{figure}
</pre>
* Use 
    \renewcommand{\baselinestretch}{x} 
in the preamble of your document, where x is typically below 1 to save space.
* Use 
    \usepackage{microtype}
* etc
