How to Double Space in LaTeX
The fix
To double space in LaTeX, load \usepackage{setspace} and add \doublespacing in the preamble (use \onehalfspacing for 1.5 spacing). For a specific region only, wrap it in \begin{spacing}{2} ... \end{spacing}. Many thesis offices require double or 1.5 spacing.
Example
\usepackage{setspace}
\doublespacing % whole document
% \onehalfspacing % 1.5 spacing
% Local region:
\begin{spacing}{1.5}
Just this part is 1.5-spaced.
\end{spacing}Frequently asked questions
How do I set 1.5 line spacing?
Load setspace and use \onehalfspacing, or \setstretch{1.5} for an exact factor. \doublespacing gives double spacing.
Why does double spacing also stretch my table of contents?
setspace affects everything. Wrap the TOC or references in \begin{singlespace} ... \end{singlespace} to keep them single-spaced while the body stays double.
