How to have double-spacing effect in LaTeX?

Answer

Add

\usepackage{setspace} \doublespacing

to the preamble. The whole document will be double-spaced including bibliography. Footnotes, figures, and tables will still be single-spaced. If you want a part of the text still be single-spaced, include the part in the environment:

\begin{singlespace} \end{singlespace}

If you want to have other spacing effect for a part of the text, you can use the environment:

\begin{spacing}{space}...\end{spacing}

. For example, to reduce the linespacing in the bibliography and table of contents, you can use the following command

\begin{spacing}{0.9} \tableofcontents \end{spacing} ... \begin{spacing}{0.9} \bibliographystyle{plain} \bibliography{refs} \end{spacing}

The other two commands provided by the

setspace

package are

\singlespacing

and

\onehalfspacing

You can also change the other spacing by using the \setstretch command, e.g. \setstretch{1.8}. To get single-spaced, one-and-half-spaced, and doublespaced effects, you can also use \setstretch{1}, \setstretch{1.5} and \setstretch{2} respectively.
