I use these two packages:

\usepackage[left=3cm, right=2cm, top=2cm, bottom=2cm]{geometry}

\usepackage[ruled,linesnumbered]{algorithm2e}

My algorithm margin does not align with the text; for example:

enter image description here

Ideally, I would want the vertical lines wrapping the algorithm to be exactly as wide as the text margin before and after.

The code used:

\documentclass[12pt, conference]{article}
\usepackage[left=3cm, right=2cm, top=2cm, bottom=2cm]{geometry}
\usepackage[ruled,linesnumbered]{algorithm2e}
\usepackage[bookmarks=true]{hyperref}
\usepackage[font=footnotesize,labelfont=bf]{caption}

\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{fancyhdr}
\usepackage{setspace}
\usepackage{commath}
\usepackage{mathtools, nccmath}
\usepackage{tocloft}


\begin{document}
\onehalfspacing





\title{
\vspace{-3cm}
     \begin{center}
    \begin{Huge}
        Big title \\
    \end{Huge}
    \vspace{0.8cm}
    \begin{Large}
    \author{Some name}
    \end{Large}
    \end{center}
    \date{}

}

\maketitle
\vspace{-0.8cm}
\abstract

\paragraph{Some title}

\bigskip


\begin{algorithm}[h]
%\setlength{\algomargin}{-2em}
\caption{Example Algorithm}\label{alg:alg_title}
\DontPrintSemicolon

\KwResult{$S$}
$S \gets \emptyset$\;

\For{$i=0, i < k$}{
  $x \gets 2$\;
  $x \gets 2$\;
  $x \gets 2$\;
  $S$.insert($x$)\;
 }
\end{algorithm}

\clearpage
\subsection{Examples}

\end{document}

Note: if i changed the type from [h] to [H], it aligns perfectly on the left of the page, but goes even more out of bounds on the right.

I tried the following commands from algorithm2e:

\leftskip
\rightskip
\DecMargin{length}
\IncMargin{length}
\algomargin

but nothing seems to work. Would appreciate any help.

Try this code. (algorithm2e is fine)

Define \title and \author and use

\begin{abstract}
    abstract text
\end{abstract}

after \maketitle

a

If you want to see the margins try

 \usepackage[left=3cm, right=2cm, top=2cm, bottom=2cm, showframe]{geometry}

.

\documentclass[12pt, conference]{article}
\usepackage[left=3cm, right=2cm, top=2cm, bottom=2cm]{geometry}
\usepackage[ruled,linesnumbered]{algorithm2e}
\usepackage[bookmarks=true]{hyperref}
\usepackage[font=footnotesize,labelfont=bf]{caption}
