Single-sided vs Double-sided Documents

% Single-sided document (default for article)
\documentclass[oneside]{article}

% Double-sided document (default for book and report)

\begin{document}

\section{Sample Content}
This content will be formatted according to the chosen option.

\begin{document}

\section{Odd Page (1)}
\lipsum[1-2]
Notice the larger inner margin for binding.

\newpage

\lipsum[3-4]
The margins are mirrored compared to odd pages.

\newpage  
\section{Odd Page (3)}
\lipsum[5-6]
Back to the odd page margin layout.

This chapter starts on an odd page.

\chapter{Second Chapter}
\lipsum[4-6]
If the previous chapter ended on an odd page, 
a blank even page will be inserted before this chapter.

\chapter{Third Chapter}

% Not: left=1.5in,right=1in (doesn't flip for even pages)
