LaTeX Space

Space between Columns: Reduce Column Paddings

\setlength{\tabcolsep}{-2pt}   % set length to -2pt
\addtolength{\tabcolsep}{-2pt} % reduce space by -2pt

Space between Rows: \def\arraystretch{1.5}

Horizontal Alignmenti (requires package array)

p{width} % equivalent to \parbox[t]{width}
m{width} % centered vertically
b{width} % equivalent to \parbox[b]{width}

\newcolumntype{C}[2]{>{\centering\arraybackslash\hspace{#1}}m{#2}}
\newcolumntype{P}[1]{>{\centering\arraybackslash}p{#1}}

\begin{tabular{|C{-1mm}{20mm}|c|c|c|}

Wide Table Option: Shrink Table to Width

\resizebox{\columnwidth}{!}{ \begin{tabular}{} ...  \end{tabular} }

Math Space

\arraycolsep=5pt                  % distance between 2 columns 
\thinmuskip=3mu                   % space between ordinary and operator atoms 
\medmuskip=4mu plus 2mu minus 4mu % space between ordinary and binary atoms 
\thickmuskip=5mu plus 5mu         % space between ordinary and relation atoms 

Vertical Space:

\setlength\jot{-30pt}
\renewcommand\arraystretch{1}

\def\>{\mskip\medmuskip}
\def\;{\mskip\thickmuskip}
\def\!{\mskip-\thinmuskip

Before/After Math Expressions:

\abovedisplayskip=12pt plus 3pt minus 9pt 
\belowdisplayskip=12pt plus 3pt minus 9pt

\abovedisplayshortskip=0pt plus 3pt 
\belowdisplayshortskip=7pt plus 3pt minus 4pt

Iteration and Emulation Space

\def\itemhook{\topsep=1ex \itemsep=0ex}
\def\enumhook{\topsep=0ex \itemsep=0ex}
\def\descripthook{\topsep=0ex \itemsep=0ex}

Heading Space

\usepackage[medium,compact]{titlesec}
\titlespacing*{\section}{0pt}{*0.8}{*0.8}
\titlespacing*{\subsection}{0pt}{*0.8}{*0.8}
\titlespacing*{\subsubsection}{0pt}{*0.3}{*0.3}

Caption Space

\abovecaptionskip=3pt % above caption
\belowcaptionskip=3pt % below caption

Vertical Space for Flating

\textfloatsep=3pt % between top and bottom of float and text
\intextsep=3pt    % between floats

Modify Enumeration: \renewcommand{\labelenumi}{[\Alph{enumi}]}

Figure

\begin{wrapfigure}[16]{r}{0.6\textwidth}  % [16] is optional, generally works better
\vspace{-20pt}
\includegraphics[width=0.59\textwidth]{Figure}   
\caption{Figure Caption} \label{Fig:Caption}
\vspace{-20pt}
\end{wrapfigure} 

\begin{figure}

\includegraphics[width=\textwidth]{Figure-1}
  \captionof{figure}{Figure 1 Caption}
  \label{Figure-1-label}
