# Headers and Footers in LaTeX - fancyhdr and Page Styles

> Learn how to customize headers and footers in LaTeX with page styles and fancyhdr. Add page numbers, section titles, dates, and Page X of Y layouts.

Headers and footers control the information that appears at the top and bottom of each page. In LaTeX, the usual workflow is simple: keep page numbering separate, then use page styles or `fancyhdr` to place the page number, section title, date, or document title where you want it.

<Info>
  **Quick answer**:

  ```latex theme={null}
  \usepackage{fancyhdr}
  \pagestyle{fancy}
  \fancyhf{}
  \fancyhead[L]{Section Title}
  \fancyfoot[C]{\thepage}
  ```

  Use built-in page styles for simple cases and `fancyhdr` when you need custom header and footer content.

## When To Use Page Numbering vs Headers and Footers

Use [Page numbering](/learn/latex/formatting/page-numbering) when your main question is:

* how to switch between roman and arabic numbers
* how to restart numbering
* how to hide numbers on selected pages
* how to show `Page X of Y`

Use this page when your main question is:

* how to put the page number in a specific place
* how to show chapter or section titles in the header
* how to create different header/footer styles for different pages
* how to control header and footer rules with `fancyhdr`

## Understanding Page Styles

### Default Page Styles

LaTeX provides four built-in page styles:

| Style        | Description          | Header                | Footer      |
| ------------ | -------------------- | --------------------- | ----------- |
| `plain`      | Default for chapters | Empty                 | Page number |
| `empty`      | Completely blank     | Empty                 | Empty       |
| `headings`   | Automatic headers    | Section/chapter names | Page number |
| `myheadings` | Manual headers       | User-defined content  | Page number |

<CodeGroup>
  ```latex basic-styles.tex theme={null}
  \documentclass{article}
  \begin{document}

  % Set page style for entire document
  \pagestyle{headings}

  % Or change style for current page only
  \thispagestyle{empty}

  \section{Introduction}
  This page will have the style set above.

  \newpage
  \section{Methods}
  This page continues with the document page style.

  \end{document}
  ```
</CodeGroup>

## The fancyhdr Package

The `fancyhdr` package provides complete control over headers and footers.

### Basic Setup

<CodeGroup>
  ```latex fancyhdr-basic.tex theme={null}
  \documentclass{article}
  \usepackage{fancyhdr}

  % Activate fancy page style
  \pagestyle{fancy}

  % Clear default headers and footers
  \fancyhf{}

  % Set headers and footers
  \fancyhead[L]{Left Header}
  \fancyhead[C]{Center Header}  
  \fancyhead[R]{Right Header}
  \fancyfoot[L]{Left Footer}
  \fancyfoot[C]{Page \thepage}
  \fancyfoot[R]{Right Footer}

  % Customize the line under header
  \renewcommand{\headrulewidth}{0.4pt}
  \renewcommand{\footrulewidth}{0.4pt}

  \begin{document}

  \section{Sample Content}
  This page demonstrates basic header and footer customization.

  \newpage
  \section{More Content}
  Headers and footers appear consistently across pages.

  \end{document}
  ```
</CodeGroup>

### Position Specifiers

<CodeGroup>
  ```latex position-specifiers.tex theme={null}
  \documentclass[twoside]{article}
  \usepackage{fancyhdr}
  \pagestyle{fancy}
  \fancyhf{}

  % For two-sided documents
  \fancyhead[LE,RO]{\thepage}  % Left on Even pages, Right on Odd pages
  \fancyhead[LO,RE]{\leftmark} % Left on Odd pages, Right on Even pages

  % Alternative: use combinations
  \fancyhead[L]{\ifnum\value{page}=1 Title Page \else \leftmark \fi}
  \fancyfoot[C]{Footer text}

  % For one-sided documents, use simple positions:
  % L (Left), C (Center), R (Right)

  \begin{document}

  \section{Introduction}
  Content for testing headers...

  \newpage
  \section{Methods}
  More content to show header changes...

  \end{document}
  ```
</CodeGroup>

## Advanced Header Customization

### Dynamic Content

<CodeGroup>
  ```latex dynamic-headers.tex theme={null}
  \documentclass{article}

  % Dynamic page information
  \fancyhead[L]{\leftmark}
  \fancyhead[R]{\today}
  \fancyfoot[L]{Document Title}
  \fancyfoot[C]{Page \thepage\ of \pageref{LastPage}}
  \fancyfoot[R]{Author Name}

  % Custom header rule
  \renewcommand{\headrulewidth}{0.5pt}
  \renewcommand{\headrule}{\hbox to\headwidth{\color{blue}\leaders\hrule height \headrulewidth\hfill}}

  % Different style for first page
  \fancypagestyle{firststyle}{%
    \fancyhf{}
    \fancyfoot[C]{\thepage}
    \renewcommand{\headrulewidth}{0pt}
  }

  \begin{document}

  \thispagestyle{firststyle}
  \title{Document Title}
  \author{Author Name}
  \maketitle

</CodeGroup>

## Troubleshooting Common Issues

### Header Height Problems

<CodeGroup>
  ```latex header-height.tex theme={null}
  \documentclass{article}
  \usepackage{fancyhdr}

  % Set appropriate header height BEFORE using fancy
  \setlength{\headheight}{30pt}  % Adjust as needed

  \pagestyle{fancy}
  \fancyhf{}

  % Multi-line header that needs more space
  \fancyhead[L]{%
    Line 1\\Line 2\\Line 3
  }

  % If you get warnings about headheight, increase it:
  % \addtolength{\headheight}{5pt}

  \begin{document}
  Content here...
  \end{document}
  ```
</CodeGroup>

### Page Break Issues

<CodeGroup>
  ```latex page-break-issues.tex theme={null}
  \documentclass{article}
  \usepackage{fancyhdr}

  \pagestyle{fancy}
  \fancyhf{}

  % Prevent headers from affecting page breaks
  \fancyhead[L]{\leftmark}
  \fancyhead[R]{\thepage}

  % Use phantom content to prevent widow/orphan issues
  \fancyfoot[C]{%
    \phantom{Invisible content for spacing}
    Page \thepage
  }

  % Adjust penalties if needed
  \clubpenalty=10000
  \widowpenalty=10000

  \begin{document}

  Content that flows across pages...

  \end{document}
  ```
</CodeGroup>

## Best Practices

<Tip>
  **Header and footer guidelines:**

  1. **Keep it simple** - Too much information clutters the page
  2. **Be consistent** - Use the same style throughout similar documents
  3. **Consider your audience** - Academic vs. business documents have different conventions
  4. **Test thoroughly** - Check headers on all page types (first, last, odd, even)
  5. **Mind the margins** - Ensure headers don't overlap with main content
  6. **Use semantic marking** - Let LaTeX generate section names automatically when possible
</Tip>

### Professional Formatting

<CodeGroup>
  ```latex professional-example.tex theme={null}
  \documentclass[11pt,letterpaper]{article}
  \usepackage{fancyhdr}
  \usepackage{lastpage}

  % Professional document setup
  \pagestyle{fancy}
  \fancyhf{}

  % Header: document info on left, page on right
  \fancyhead[L]{\textbf{Project Report} | \leftmark}
  \fancyhead[R]{Page \thepage\ of \pageref{LastPage}}

  % Footer: company info and date
  \fancyfoot[L]{Company Name}
  \fancyfoot[C]{\textit{Confidential}}
  \fancyfoot[R]{\today}

  % Clean lines
  \renewcommand{\headrulewidth}{0.5pt}
  \renewcommand{\footrulewidth}{0.3pt}

  % Adjust spacing
  \setlength{\headheight}{14pt}

  \begin{document}

  \section{Executive Summary}
  Professional document content...

  \end{document}
  ```
</CodeGroup>
