[Tex/LaTex] Control space between lines

Question

I have need to control line spaces in the certification page that has following format:

Line 1.1
Line 1.2
Line 2.1
Line 2.2
...
Line n.1
Line n.2

(These are short lines.) I need to single space between lines x.1 and x.2 but double space for the rest. I tried putting

Line x.1
\singlespacing
Line x.2

But the gap between 2 lines becomes very big. What's the right way to format this?

Thanks,

Answer 1

Use the singlespace environment to limit the effect. There are onehalfspace and doublespace environments as well.

Please note that there's a singlespace* environment as well, which does not add a \vskip\baselineskip at the beginning.

\documentclass{article}

\usepackage{setspace}

\begin{document}
\doublespacing
All

is

doublespaced

here
\begin{singlespace}
But

here

only

singlespaced
\end{singlespace}
Double

spacing

again
