# Using lower-case roman numerals in enumerate lists

when I use

\begin{enumerate}[I]
\item
...


I get

I
II


how I can get

i
ii


?

I try with

\renewcommand{\theenumi}{\roman{enumi}}
\renewcommand{\labelenumi}{\theenumi}


in the begin of file, but not fix the problem.

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

\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}

• There's also the paralist package, that works just like enumerate in this case. – Christian May 2 '12 at 6:06
• Unfortunately, with paralist the 8th item is misaligned (with enumerate it's correct). – Javier Bezos May 2 '12 at 7:04

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. – Guido Apr 2 '13 at 11:29
• but this was useful information, so thanks. – Tasos Papastylianou Jan 1 '17 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? – Dmitri Zaitsev Jul 5 at 1:53
• @DmitriZaitsev You might want to check out enumitem package (with package option shortlabels. It's more customizable than enumerate. – 6005 Nov 19 at 1:36

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

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


or

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

• Just use [label=(\roman*)] – Smaillns May 31 at 11:58
• @Smaillns, have you tested it? This would require an extension package. – PatrickT Jun 2 at 14:20
• \usepackage{enumitem} – Smaillns Jun 5 at 10:32
• Note: you can remove the braket "()", and add what you want, for instance \begin{enumerate}[label=\roman*] – Smaillns Jun 5 at 10:40
• This is covered by Werner's answer, while my answer was focused on the beamer class specifically. – PatrickT Jun 5 at 16:47
