# Text Formatting in LaTeX

> Master text formatting in LaTeX including font sizes, styles, colors, alignment, and special formatting techniques.

Beyond the basics of bold and italic, LaTeX offers extensive text formatting capabilities. This guide covers font sizes, families, shapes, colors, and advanced formatting options.

<Info>
  **Quick tip**: LaTeX separates content from presentation. Define your formatting once and apply it consistently throughout your document.

## Font Sizes

LaTeX provides ten standard font size commands:

<Tabs>
  <Tab title="Code">
    <CodeGroup>
      ```latex font-sizes.tex theme={null}
      \documentclass{article}
      \begin{document}

      {\tiny This is tiny text}\\
      {\scriptsize This is scriptsize text}\\
      {\footnotesize This is footnotesize text}\\
      {\small This is small text}\\
      {\normalsize This is normalsize text}\\
      {\large This is large text}\\
      {\Large This is Large text}\\
      {\LARGE This is LARGE text}\\
      {\huge This is huge text}\\
      {\Huge This is Huge text}

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

  <Tab title="Rendered output">
    <div className="latex-preview-shell">
      <div className="latex-preview-paper latex-preview-paper--narrow">
        <p className="latex-preview-paragraph latex-preview-size-tiny">This is tiny text</p>
        <p className="latex-preview-paragraph" style={{ fontSize: "0.78rem" }}>This is scriptsize text</p>
        <p className="latex-preview-paragraph" style={{ fontSize: "0.84rem" }}>This is footnotesize text</p>
        <p className="latex-preview-paragraph latex-preview-size-small">This is small text</p>
        <p className="latex-preview-paragraph">This is normalsize text</p>
        <p className="latex-preview-paragraph latex-preview-size-large">This is large text</p>
        <p className="latex-preview-paragraph" style={{ fontSize: "1.28rem" }}>This is Large text</p>
        <p className="latex-preview-paragraph" style={{ fontSize: "1.46rem" }}>This is LARGE text</p>
        <p className="latex-preview-paragraph" style={{ fontSize: "1.72rem" }}>This is huge text</p>
        <p className="latex-preview-paragraph latex-preview-size-huge">This is Huge text</p>
      </div>
    </div>
  </Tab>
</Tabs>

### Using Font Sizes

<CodeGroup>
  ```latex using-sizes.tex theme={null}
  % Inline usage
  This is {\large important} text.

  % Block usage
  {\Large
  This entire paragraph is in Large size.
  All text here maintains the same size.
  }

  % Environment usage
  \begin{large}
  Everything in this environment is large.
  \end{large}
  ```
</CodeGroup>

## Font Families

LaTeX has three main font families:

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

  % Roman (serif) - default
  \textrm{This is Roman text (serif)}

  % Sans serif
  \textsf{This is Sans Serif text}

  % Typewriter (monospace)
  \texttt{This is Typewriter text}

  % Combining with other formatting
  \textsf{\textbf{Bold Sans Serif}}
  \texttt{\textit{Italic Typewriter}}

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

### Setting Default Font Family

<CodeGroup>
  ```latex default-family.tex theme={null}
  % Make sans serif the default
  \renewcommand{\familydefault}{\sfdefault}

  % Make typewriter the default
  \renewcommand{\familydefault}{\ttdefault}

  % Return to roman (default)
  \renewcommand{\familydefault}{\rmdefault}
  ```
</CodeGroup>

## Font Shapes and Series

### Font Shapes

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

  % Upright (default)
  \textup{Upright text}

  % Italic
  \textit{Italic text}

  % Slanted (different from italic)
  \textsl{Slanted text}

  % Small caps
  \textsc{Small Capitals}

  % Emphasis (context-aware)
  \emph{Emphasized text}

  % Nested emphasis
  \textit{Italic with \emph{emphasized} text}

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

### Font Series (Weight)

<CodeGroup>
  ```latex font-weight.tex theme={null}
  % Medium (default)
  \textmd{Medium weight text}

  % Bold
  \textbf{Bold text}

  Each line is individually centered.
  \end{center}

  % Right aligned
  \begin{flushright}
  This text is aligned to the right edge.\\
  All lines align to the right margin.
  \end{flushright}

  % Justified (default for normal text)
  This is justified text, which is the default in LaTeX. 
  The text is aligned to both left and right margins, 
  with spacing adjusted between words.

  % Ragged right (unjustified)
  \raggedright
  This text has a ragged right edge. 
  Lines break naturally without justification.

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

  Normal \scalebox{2}{Scaled 2x} text

  \scalebox{1.5}[0.5]{Stretched horizontally}

  \scalebox{0.5}[1.5]{Stretched vertically}

  \resizebox{3cm}{!}{Resized to 3cm width}

  \resizebox{!}{1cm}{Resized to 1cm height}

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

## Custom Commands for Consistent Formatting

<CodeGroup>
  ```latex custom-commands.tex theme={null}
  \documentclass{article}
  \usepackage{xcolor}

  % Define custom commands
  \newcommand{\keyword}[1]{\textbf{\textcolor{blue}{#1}}}
  \newcommand{\important}[1]{\textcolor{red}{\textbf{#1}}}
  \newcommand{\code}[1]{\texttt{\colorbox{gray!20}{#1}}}
  \newcommand{\term}[1]{\textit{#1}}

  \begin{document}

  The \keyword{function} keyword declares a new function.

  \important{Warning:} This action cannot be undone.

  Use the \code{print()} function to display output.

  The \term{algorithm} processes data efficiently.

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

## Multilingual Text

<CodeGroup>
  ```latex multilingual.tex theme={null}
  \documentclass{article}
  \usepackage[utf8]{inputenc}
  \usepackage[T1]{fontenc}
  \usepackage{babel}

  % For XeLaTeX/LuaLaTeX
  % \usepackage{fontspec}
  % \usepackage{polyglossia}

  \begin{document}

  % Accented characters
  café, naïve, résumé, Zürich

  % Special characters
  €100, £50, ¥1000, °C, ±5%

  % Different languages
  \foreignlanguage{spanish}{¡Hola! ¿Cómo estás?}
  \foreignlanguage{german}{Größe, Übung, ähnlich}
  \foreignlanguage{french}{Château, œuvre, garçon}

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

## Best Practices

<Tip>
  **Formatting guidelines:**

  1. **Semantic markup**: Use `\emph{}` for emphasis, not just `\textit{}`
  2. **Consistency**: Define custom commands for repeated formatting
  3. **Avoid hardcoding**: Use relative sizes (em, ex) not absolute (pt)
  4. **Color sparingly**: Too many colors reduce professionalism
  5. **Test output**: Check how formatting appears in final PDF
</Tip>

## Common Pitfalls

<Warning>
  **Avoid these mistakes:**

  1. **Over-formatting**: Don't use too many different styles
  2. **Manual spacing**: Let LaTeX handle spacing automatically
  3. **Absolute sizes**: Use relative sizes for better scaling
  4. **Direct formatting**: Define styles once, reuse throughout
  5. **Poor contrast**: Ensure colored text is readable
</Warning>

## Quick Reference

| Command          | Purpose      | Example                 |
| ---------------- | ------------ | ----------------------- |
| `\large`         | Larger text  | `{\large Big}`          |
| `\textbf{}`      | Bold         | `\textbf{Bold}`         |
| `\textit{}`      | Italic       | `\textit{Italic}`       |
| `\texttt{}`      | Monospace    | `\texttt{Code}`         |
| `\textsc{}`      | Small caps   | `\textsc{Name}`         |
| `\textcolor{}{}` | Colored text | `\textcolor{red}{Red}`  |
| `\colorbox{}{}`  | Background   | `\colorbox{yellow}{Hi}` |
| `\underline{}`   | Underline    | `\underline{Text}`      |
