Time for action – sparing an almost empty page

We shall modify our example a bit. This time, we will try to avoid a nearly empty page by squeezing their text to the preceding page.

1. Remove the command \newpage from our example and switch to 11pt base font. This time, use less filler text in the subsection:

   \documentclass[a4paper,11pt]{book}
   \usepackage[english]{babel}
   \usepackage{blindtext}
   \usepackage[a4paper, inner=1.5cm, outer=3cm, top=2cm,
   bottom=3cm, bindingoffset=1cm]{geometry}
   \begin{document}
   \chapter{Exploring the page layout}
   In this chapter we will study the layout of pages.
   \section{Some filler text}
   \blindtext
   \section{A lot more filler text}
   More dummy text will follow.
   \subsection{Plenty of filler text}
   \blindtext[3]
   \end{document}

2. Typeset, and the result will consist of two pages:

   
   

3. Insert this command right after the \subsection line:

   \enlargethispage{\baselineskip}

4. Typeset. Now our document fits in only one page:

We used the command \enlargethispage to squeeze...
