Change the list numbering format of enumerate in LaTeX

In this tutorial, I will show you how to change the list numbering format of the enumerate in LaTeX.

These are the available list numbering formats:

• \arabic*: This is the default numbering format.
• \roman*: You can use it to get the small roman letter for list numbering.
• \Roman*: This is used to get the capital roman letter for list numbering.
• \alph*: This is used to get the small alphabets for list numbering.
• \Alph*: To get capital alphabets for list numbering.

Change list numbering in all formats in LaTeX

You can use those formats with \begin{enumerate}[label=<format>] to get your preferred list numbering. But first, you have to load the enumitem package in the preamble of your document.

\documentclass{article}
\usepackage{enumitem}

\begin{document}

\noindent list with small Roman letters with \verb|[label=\roman*]|:
\begin{enumerate}[label=\roman*]
  \item First item
  \item Second item
  \item Third item
\end{enumerate}
list with capital Roman letters with \verb|[label=\Roman*]|:
\begin{enumerate}[label=\Roman*]
  \item First item
  \item Second item
  \item Third item
\end{enumerate}
list with small alphabets with \verb|[label=\alph*]|:
\begin{enumerate}[label=\alph*]
  \item First item
  \item Second item
  \item Third item
\end{enumerate}
list with capital alphabets with \verb|[label=\Alph*]|:
\begin{enumerate}[label=\Alph*]
  \item First item
  \item Second item
  \item Third item
\end{enumerate}

\end{document}

Output:

Also, you can put those formats with (<format>), <format>), and <format>. to get this type of output (a), i), and ii..

\documentclass{article}
\usepackage{enumitem}

\begin{document}

\noindent list with small Roman letters with \verb|[label=(\roman*)]|:
\begin{enumerate}[label=(\roman*)]
  \item First item
  \item Second item
  \item Third item
\end{enumerate}
list with capital Roman letters with \verb|[label=\Roman*)]|:
\begin{enumerate}[label=\Roman*)]
  \item First item
  \item Second item
  \item Third item
\end{enumerate}
list with small alphabets with \verb|[label=\alph*.]|:
\begin{enumerate}[label=\alph*.]
  \item First item
  \item Second item
  \item Third item
\end{enumerate}
list with capital alphabets with \verb|[label=\Alph*:]|:
\begin{enumerate}[label=\Alph*:]
  \item First item
  \item Second item
  \item Third item
\end{enumerate}

\end{document}

Output:
