How to increase spacing between two lines?

Question

I am new to LaTeX. I was writing a document in LaTeX. I want to increase the spacing between the vertical lines, I can use \vspace{2mm} but that is not possible to write at end of every line.

So can you please tell me a code for this.

Answer 1

There's also the setspace package (place in preamble):

\usepackage{setspace}
\onehalfspacing
%\doublespacing

There's \openup macro (to use in text).

\openup .5em
\lipsum[3]}

You could also

\baselineskip=1.5\baselineskip
\lipsum[3]}

Answer 2

The 2nd argument to \fontsize provides the default baselineskip (the first argument is the font size)

\documentclass{article}
\usepackage{lipsum}
\begin{document}
\lipsum[1]

\fontsize{10pt}{14pt}\selectfont
\lipsum[1]

\fontsize{10pt}{10pt}\selectfont
\lipsum[1]
\end{document}
