Two-column documents can be easily created by passing the parameter \twocolumn to the document class statement. If you need more flexibility in the column layout, or to create a document with multiple columns, the package multicol provides a set of commands for that. This article explains how to import and use that package. Contents 1 Introduction 2 Column separation 3 Unbalanced columns 4 Inserting floating elements 5 Inserting vertical rulers 6 Further reading  Introduction A flexible tool to handle multicolumn documents in LaTeX is multicol, as used in the following example: \documentclass{article} \usepackage[utf8]{inputenc} \usepackage[english]{babel}   \usepackage{multicol}   \begin{document} \begin{multicols}{3} [ \section{First Section} All human things are subject to decay. And when fate summons, Monarchs must obey. ] Hello, here is some text without a meaning. This text should show what a printed text will look like at this place. If you read this text, you will get no information. Really? Is there no information? Is there... \end{multicols}   \end{document} To import the package, the line \usepackage{multicol} is added to the preamble. Once the package is imported, the environment multicols can be used. The environment takes two parameters: Number of columns. This parameter must be passed inside braces, and its value is 3 in the example. "Header text", which is inserted in between square brackets. This is optional and will be displayed on top of the multicolumn text. Any LaTeX command can be used here, except for floating elements such as figures and tables. In the example, the section title and a small paragraph are set here. The text enclosed inside the tags \begin{multicols} and \end{multicols} is printed in multicolumn format.   Open an example of the multicols package in Overleaf  Column separation The column separation is determined by \columnsep. See the example below: \documentclass{article} \usepackage[utf8]{inputenc} \usepackage[english]{babel}   \usepackage{multicol} \setlength{\columnsep}{1cm}   \begin{document} \begin{multicols}{2} [ \section{First Section} All human things are subject to decay. And when fate summons, Monarchs must obey. ] Hello, here is some text without a meaning. This text should show what a printed text will look like at this place. If you read this text, you will get no information. Really? Is there no information? Is there... \end{multicols}   \end{document} Here, the command \setlength{\columnsep}{1cm} sets the column separation to 1cm. See Lengths in LaTeX for a list of available units.   Open an example of the multicols package in Overleaf  Unbalanced columns In the default multicols environment the columns are balanced so each one contains the same amount of text. This default format can be changed by the stared environment multicols*: \begin{multicols*}{3} [ \section{First Section} All human things are subject to decay. And when fate summons, Monarchs must obey. ] Hello, here is some text without a meaning. This text should show what a printed text will look like at this place. If you read this text, you will get no information. Really? Is there no information? Is there... \end{multicols*}   \end{document} In this case the text is printed in a column till the end of the page is reached, then the in continues in the next column and so on.   Open an example of the multicols package in Overleaf  Inserting floating elements Floating elements (tables and figures) can be inserted in a multicolumn document with wrapfig and wraptable. \begin{multicols}{2} [ \section{First Section} All human things are subject to decay. And when fate summons, Monarchs must obey. ]   Hello, here is some text without a meaning. This text should show what a printed text will look like at this place. If you read this text, you will get no information. Really? Is there no information? Is there.   \vfill   \begin{wrapfigure}{l}{0.7\linewidth} \includegraphics[width=\linewidth]{./lion-logo.jpg} \caption{This is the former Share\LaTeX{} logo} \end{wrapfigure}   A blind text like this gives you information about the selected font, how the letters are written and an impression of the look. This text should contain all...   \begin{wraptable}{l}{0.7\linewidth} \centering \begin{tabular}{|c|c|} \hline Name & ISO \\ \hline Afghanistan & AF \\ Aland Islands & AX \\ Albania &AL \\ Algeria &DZ \\ American Samoa & AS \\ Andorra & AD \\ Angola & AO \\ \hline \end{tabular} \caption{Table, floating element} \label{table:ta} \end{wraptable}   \end{multicols}   \end{document} Floats in the multicol package are poorly supported in the current version. Elements inserted with the conventional figure* and table* environments will show up only at the top or bottom of the next page after they are inserted, and will break the layout. The example presented here is a workaround, but you may expect some rough edges. For instance, if the float width is set to \linewidth it causes a weird text overlapping. This said, below is a brief description of the commands: \usepackage{wrapfig}. Put this line in the preamble to import the package wrapfig The environment wrapfigure will insert a figure wrapped in the text. For more information and further examples about this environment see Positioning images and tables. The environment wraptible is the equivalent to wrapfigure but for tables. See Positioning images and tables for more information.   Open an example of the multicols package in Overleaf  Inserting vertical rulers A vertical ruler can be inserted as column separator to may improve readability in some documents: \documentclass{article} \usepackage[utf8]{inputenc} \usepackage[english]{babel}   \usepackage{multicol} \usepackage{color}   \usepackage{comment}   \setlength{\columnseprule}{1pt} \def\columnseprulecolor{\color{blue}}   \begin{document}   \begin{multicols}{3} [ \section{First Section} All human things are subject to decay. And when fate summons, Monarchs must obey. ]   Hello, here is some text without a meaning. This text should show what a printed text will look like at this place.   If you read this text, you will get no information. Really? Is there no information? Is there.   \columnbreak   This will be in a new column, here is some text without a meaning. This text should show what a printed text will look like at this place.   If you read this text, you will get no information. Really? Is there no information? Is there... \end{multicols}   Something else here. The text should not be multicolumned in this part   \end{document} As you see, the column separator can be set to a specific colour also. Below a description of each command: \usepackage{color}. This line is inserted in the preamble to enable the use of several colours within the document. \setlength{\columnseprule}{1pt} This determines the width of the ruler to be used as column separator, it's set to 0 by default. In the example a column whose width is 1pt is printed. \def\columnseprulecolor{\color{blue}} The colour of the separator ruler is set to blue. See the article about using colours in LaTeX for more information on colour manipulation. \columnbreak This command inserts a column breakpoint. In this case, the behaviour of the text is different from what you may expect. The column break is inserted, then the paragraphs before the breakpoint are evenly distributed to fill all available space. In the example, the second paragraph is at the bottom of the column and a blank space is inserted in between the second and the first paragraphs.   Open an example of the multicols package in Overleaf  Further reading For more information see: Paragraphs and new lines Bold, italics and underlining Lists Inserting Images Tables Positioning images and tables Lengths in LaTeX Paragraph formatting Page size and margins Single sided and double sided documents Using colours in LaTeX Footnotes Margin notes multicols package documentation.
