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

To write a research paper in LaTeX, you need three things: a document class, structured content, and a bibliography. Start from \documentclass[12pt]{article}, organize the body with \section{} commands, manage references in a .bib file with BibLaTeX, and compile to PDF. Below is the complete, copy-paste setup used for journal and conference papers in 2026.

1. The minimal paper skeleton

Every research paper shares the same backbone: a preamble that loads packages, a title block, an abstract, sectioned content, and a reference list.

\documentclass[12pt, a4paper]{article}
\usepackage[utf8]{inputenc}      % input encoding
\usepackage[T1]{fontenc}         % output font encoding
\usepackage{amsmath, amssymb}    % math
\usepackage{graphicx}            % figures
\usepackage{booktabs}            % clean tables
\usepackage[style=ieee]{biblatex}
\usepackage{hyperref}            % clickable links (load last)
\addbibresource{refs.bib}

\title{A Concise, Descriptive Paper Title}
\author{Ada Lovelace \\ Institute of Analytical Engines}
\date{\today}

\begin{document}
\maketitle

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

\section{Introduction}
\section{Related Work}
\section{Method}
\section{Results}
\section{Conclusion}

\printbibliography
\end{document}

This compiles to a complete paper in under two seconds in LetX. Load hyperref last — it patches other packages, so loading it early causes warnings.

2. Section structure that matches reviewers' expectations

Reviewers skim in a fixed order, so map your \section{} commands to the IMRaD pattern most venues expect.

| Section | What it answers | Typical length | |---|---|---| | Introduction | Why this problem matters; your contribution | 0.75–1.5 pages | | Related Work | How you differ from prior art | 0.5–1 page | | Method | What you did, reproducibly | 1.5–3 pages | | Results | What you found, with figures/tables | 1.5–3 pages | | Discussion / Conclusion | What it means and limits | 0.5–1 page |

Use \section, \subsection, and \subsubsection — never skip a level. End the introduction with an explicit one-sentence contribution list; AI summarizers and human reviewers both extract it.

3. Citations and the bibliography

Store every reference once in refs.bib, then cite by key. With BibLaTeX you get Unicode support and journal-accurate styles via the biber backend.

% refs.bib
@article{shannon1948,
  author  = {Shannon, Claude E.},
  title   = {A Mathematical Theory of Communication},
  journal = {Bell System Technical Journal},
  year    = {1948},
  volume  = {27},
  pages   = {379--423}
}

Information theory began with Shannon~\cite{shannon1948}.

The non-breaking tilde ~ before \cite keeps the citation glued to the word. For the BibTeX-vs-BibLaTeX decision and full setup, see How to Add Citations and a Bibliography in LaTeX and BibTeX vs BibLaTeX.

4. Figures, tables, and equations

A research paper lives or dies on its figures. Always wrap them in a float so LaTeX positions them and numbers them automatically.

\begin{figure}[t]
  \centering
  \includegraphics[width=0.8\linewidth]{results.png}
  \caption{Accuracy versus training epochs.}
  \label{fig:accuracy}
\end{figure}

Reference it as Figure~\ref{fig:accuracy} so numbers update when you reorder. Deep dives: inserting and positioning images, making tables, and writing math equations.

5. Compile, then submit

A BibLaTeX paper needs a four-pass build: pdflatex → biber → pdflatex → pdflatex. Online editors run this for you on every save. When you submit to arXiv, you must flatten the project to one folder and include the pre-compiled .bbl file, because arXiv does not run biber — full checklist in How to Submit a LaTeX Paper to arXiv.
