LaTeX Indentation
The default indentation style can be configured in several ways.
Contents
Paragraphs
The default behavior is to indent all paragraphs except for those immediately following a section title. Paragraph indentation length is set by the document type; see here for some details.
To force indentation on all paragraphs, include the indentfirst package at the top of the document.
\usepackage{indentfirst}To set an explicit indentation length, try:
\setlength\parindent{24pt}
