\usepackage{bbding}
\usepackage{pifont}
\usepackage{enumitem}
\usepackage{tcolorbox,enumitem,setspace}
\begin{document}
\begin{tcbposter}[
  poster = {
    columns=1,
    rows=2,
    spacing=3mm,
    height=14cm,
    width=12cm,
  },
]

\posterbox[colframe=red,width=4cm,height=4cm]{column=1}{
 %\begin{itemize}[leftmargin=0]
1. This will break to two lines

2. This will break to two lines

3. This will break to two lines


}
\end{tcbposter}

Answer 1

这是一个简单的可能性enumitem：

\documentclass{article}
\usepackage{tikz}
\usepackage{tcolorbox}
\tcbuselibrary{poster}

\usepackage{bbding}
\usepackage{pifont}
\usepackage{enumitem, setspace}

\begin{document}

\begin{tcbposter}[
  poster = {
    columns=1,
    rows=2,
    spacing=3mm,
    height=14cm,
    width=12cm,
  },
]

\posterbox[colframe=red,width=4cm,height=4cm]{column=1}{
 \begin{enumerate}[wide, leftmargin =-1em, rightmargin=-1em]
\item This will break to two lines, or even more.

\item This will break to two lines.

\item This will break to two lines.
\end{enumerate}
}
\end{tcbposter}

\end{document}

Answer 2

使用方法如下\parindent。也可以使用 进行设置\setlength。

\documentclass{article}
\usepackage{tikz}
\usepackage{tcolorbox}
\tcbuselibrary{poster}

\usepackage{bbding}
\usepackage{pifont}
\usepackage{enumitem}
\usepackage{tcolorbox,enumitem,setspace}
\begin{document}
\begin{tcbposter}[
  poster = {
    columns=1,
    rows=2,
    spacing=3mm,
    height=14cm,
    width=12cm,
  },
]

\posterbox[colframe=red,width=4cm,height=4cm]{column=1}{
 %\begin{itemize}[leftmargin=0]
\raggedright
\parindent=1em
1. This will break to two lines

2. This will break to two lines

3. This will break to two lines


}
\end{tcbposter}
\end{document}
