This is my code

\documentclass[12pt,a4paper]{book} 
\renewcommand{\baselinestretch}{1.5} 
\begin{document}
\include{Chapter1}
\end{document}

I have please a question:

I would change the line spacing (1.5 --> 1.0) of a page inside the document and not the entire document and the size of the words, how can I do please?

  • after using your code my chapters start being displayed on the left side (which is odd and wrong) - how can I make latex display them on the right (also known as the right) side again? I'm using the {book} class.

You can use \setstretch{}. If you want to only affect a certain content you can use it with a group.

enter image description here

You can also apply any size changing switches such as \small or \tiny inside the {} group as well.

Code

\documentclass[12pt,a4paper]{book} 
\usepackage{xcolor}
\usepackage{lipsum}
\usepackage{setspace}

\renewcommand{\baselinestretch}{1.5} 

\begin{document}
\lipsum[1]
{\setstretch{1.0}\color{blue}
\lipsum[2]
}
\lipsum[3]
\end{document}

    Just remember to end the paragraph before the final } (\lipsum adds a \par at its end). Using \linespread{1.5} (or some command of setspace) is better than redefining \baselinestretch.

    @researcher: You could try using the answers from LaTeX — specify font point size? and keep the change to be within a group (either inside a brace group {}, or within \begingroup, \endgroup pair. If that does not help you achieve the desired results you should post a separate question. Also, please note that you should use the full username with the @ syntax. I was only notified of this as it was a comment to an answer of mine.

  • @researcher: fontsize has two parameters, not one.

Alternatively, the following solution is a bit cleaner:

\documentclass[12pt,a4paper]{book} 
\usepackage{lipsum}
\usepackage{setspace}

\begin{document}

\onehalfspacing % Set line spacing to 1.5

\lipsum[1]

\singlespacing % Reset line spacing to 1 from here on
\lipsum[2]
\onehalfspacing % Reset line spacing to 1.5 from here on

\lipsum[3]
\end{document}

For other values, you can use e.g. \setstretch{1.125} instead of \singlespacing and \onehalfspacing.

The advantage of this method is that you don't need a closing statement, such as end{} or a curly bracket.

  • It looks like this also works (on Overleaf, at least) without adding the package setspace.

Other values

Other line spacing values that lie in between onehalf, single and double can also be achieved with:

\usepackage{setspace}

\begin{spacing}{1.125}
…
\end{spacing}

  • Note that this solution increases the spacing of all lines, if you have e.g. 2 lines, both will have the spacing of 1.125
