There are a number of ways. Here's using the enumerate package:

enter image description here

\documentclass{article}
\usepackage{enumerate}% http://ctan.org/pkg/enumerate
\begin{document}
\begin{enumerate}[I]
  \item One
  \item Two
  \item Three
\end{enumerate}

\begin{enumerate}[i]
  \item One
  \item Two
  \item Three
\end{enumerate}
\end{document}

Here's another method via the enumitem package. It yields the same output as above:

\documentclass{article}
\usepackage{enumitem}% http://ctan.org/pkg/enumitem
\begin{document}
\begin{enumerate}[label=\Roman*]
  \item One
  \item Two
  \item Three
\end{enumerate}

\begin{enumerate}[label=\roman*]
  \item One
  \item Two
  \item Three
\end{enumerate}
\end{document}

And then, without any packages:

\documentclass{article}
\renewcommand{\labelenumi}{\theenumi}
\begin{document}
\renewcommand{\theenumi}{\Roman{enumi}}%
\begin{enumerate}
  \item One
  \item Two
  \item Three
\end{enumerate}

\renewcommand{\theenumi}{\roman{enumi}}%
\begin{enumerate}
  \item One
  \item Two
  \item Three
\end{enumerate}
\end{document}

If you want to type:

I.

II.

III.

Use:

\documentclass{article}
\begin{document}
\usepackage{enumerate}
\begin{enumerate}[I.]
  \item my text
  \item my text
  \item my text
\end{enumerate}

Another possibility for [I.] is [(I)], which gives:

(I)

(II)

(III)

    The question is how to have lowercase roman numeral, not to add a period/dot after the Roman numeral.

    but this was useful information, so thanks. Jan 1, 2017 at 14:46
  • Unfortunately this package adds the side-effect of changing the indentation for the items - is there any way to avoid this change? Jul 5, 2019 at 1:53
  • @DmitriZaitsev You might want to check out enumitem package (with package option shortlabels. It's more customizable than enumerate.

If you're using the beamer class, try something like:

\setbeamertemplate{enumerate item}{(\roman{enumi})}

or

\setbeamertemplate{enumerate subitem}{(\roman{enumii})}

See: Problem with enumerate package in beamer class

    Just use [label=(\roman*)]

  • @Smaillns, have you tested it? This would require an extension package.

  • \usepackage{enumitem}

  • Note: you can remove the braket "()", and add what you want, for instance \begin{enumerate}[label=\roman*]

    This is covered by Werner's answer, while my answer was focused on the beamer class specifically.

For those using Spanish with babel package, the enumerate option \begin{enumerate}[i] does not work. To make it work, load the babel package with this option:

\usepackage[spanish,es-lcroman]{babel} 

Explanation:

Spanish babel forces the use of upper case. As the manual states:

Traditional Spanish typography discourages the use of lowercase Roman numerals.

The manual justifies this choice referencing the book José Martínez de Sousa, Diccionario de tipografía y del libro, Madrid, Paraninfo, 3.a ed., 1992.
