How to Write a Research Paper in LaTeX (2026 Guide)

By Shihab Shahriar Antor · Updated June 2026 · 11 min read

To write a research paper in LaTeX, start from \documentclass{article}, set up a preamble with packages like amsmath, graphicx, and a bibliography tool, then structure the body with \title, \abstract, \section commands, figures, tables, and \cite citations backed by a .bib file. Compile to PDF — on LetX this runs the full BibTeX pass automatically in 1–2 seconds, with real-time co-authoring.

The structure of a LaTeX research paper

A research paper in LaTeX separates content from formatting. You mark what each part is — a section, a figure, a citation — and LaTeX handles numbering, layout, and the reference list. A typical paper follows this structure:

PartLaTeXPurpose
Title block\title \author \maketitleTitle, authors, affiliations
Abstractabstract150–250 word summary
Introduction\sectionProblem, motivation, contributions
Related work\sectionPrior literature with citations
Method\sectionYour approach, equations, figures
Results\sectionTables, figures, analysis
Conclusion\sectionSummary and future work
References\bibliographyAuto-generated from .bib

A complete annotated skeleton

Copy this into a new project as a starting point. Every section is wired up — replace the placeholder text with your content:

\documentclass[11pt]{article}

\usepackage[utf8]{inputenc}
\usepackage{amsmath, amssymb}   % math
\usepackage{graphicx}           % figures
\usepackage{booktabs}           % clean tables
\usepackage{hyperref}           % links (load last)

% --- Title metadata ---
\title{Your Paper Title}
\author{First Author \\ Affiliation \and Second Author}
\date{\today}

\begin{document}
\maketitle

\begin{abstract}
A concise 150--250 word summary of the problem,
method, and key result.
\end{abstract}

\section{Introduction}
Motivate the problem and state your contributions.
We build on prior work \cite{knuth1984}.

\section{Method}
Describe your approach. Equations are easy:
\begin{equation}
  \mathcal{L} = -\sum_{i} y_i \log \hat{y}_i
\end{equation}

\section{Results}
See Table~\ref{tab:results} and Figure~\ref{fig:plot}.

\begin{table}[ht]
  \centering
  \begin{tabular}{lcc}
    \toprule
    Model & Accuracy & F1 \\
    \midrule
    Baseline & 0.81 & 0.79 \\
    Ours & 0.92 & 0.91 \\
    \bottomrule
  \end{tabular}
  \caption{Main results.}
  \label{tab:results}
\end{table}

\section{Conclusion}
Summarize findings and future directions.

\bibliographystyle{plain}
\bibliography{references}
\end{document}

Citations and the bibliography

Store references in a references.bib file and cite them by key. LaTeX builds and orders the reference list automatically — you never number citations by hand. See our deep dives on citations and bibliographies.

references.bib
@book{knuth1984,
  author    = {Donald E. Knuth},
  title     = {The TeXbook},
  publisher = {Addison-Wesley},
  year      = {1984}
}

Figures, tables, and math

  • Figures: \includegraphics inside a figure environment with \caption and \label.
  • Tables: tabular with booktabs rules; reference with Table~\ref{...}.
  • Math: the equation and align environments from amsmath.

Submitting to a journal or conference

Most venues provide a document class (e.g. IEEEtran, Springer LNCS, ACM acmart). Swap your \documentclass for theirs and move your content in. See how to write an IEEE conference paper, or start from a ready LaTeX paper template.

Write it collaboratively

Research is rarely solo. With LetX you and your co-authors edit the same paper in real time, compile in 1–2 seconds, and jump between source and PDF with SyncTeX — no install, no emailing .tex files. New to LaTeX? Start with Learn LaTeX in 30 minutes.

Write your paper with real-time co-authors — free.

Frequently asked questions

How do I start writing a research paper in LaTeX?

Start from \documentclass{article}, add a preamble with amsmath, graphicx, and a bibliography package, then write \title, an abstract, and \section commands for Introduction, Method, Results, and Conclusion. Compile to PDF — on LetX this needs no install.

What document class should I use for a research paper?

Use article for most papers. For a specific venue, use its class — IEEEtran for IEEE, acmart for ACM, or the Springer LNCS class — which set the required formatting automatically.

How do I add references to a LaTeX paper?

Store references in a .bib file, cite them with \cite{key}, and print the list with \bibliography (BibTeX) or \printbibliography (biblatex). LaTeX numbers and orders them for you.

Can I write a LaTeX paper with co-authors in real time?

Yes. LetX is a real-time collaborative LaTeX editor — multiple authors edit the same paper live, with shared compiles in 1–2 seconds and SyncTeX navigation, all in the browser.
