I’m currently writing a grant proposal and the narrative is supposed to be double-spaced. As with most of my writing, I’m using LaTeX. I’ve double-spaced a .tex document before, but I do it so infrequently that I needed to remind myself how do it. It seems the most common technique is to make use of the setspace package, which you can find here if you don’t already have it. Here are the steps necessary to double-space.

In the preamble of your document add the line usepackage{setspace}. In order to double-space your document, add the line doublespacing before begin{document}.

The setspace package also supports singlespacing, onehalfspacing, and even setstretch{1.5}, where you can change 1.5 to whatever you desire. In addition, you can make a block of text single-spaced in the middle of a double-spaced document by using begin{singlespace}stuff you want single-spacedend{singlespace}.
