# 我該如何將文件設為雙行距？

您可以使用 `\doublespacing` 由 `setspace` 套件提供的指令。以下範例使用 `\doublespacing` 於文件導言區中：

```latex
\documentclass{article}
% 選擇一個方便且較小的頁面大小
\usepackage[paperheight=18cm,paperwidth=14cm,textwidth=12cm]{geometry}
% 載入 blindtext 套件以取得虛構文字
\usepackage{blindtext}
% 載入 setspace 套件
\usepackage{setspace}
% 在導言區中使用 \doublespacing
% 會將文字改為雙倍行距
\doublespacing
\begin{document}
\blindtext[1]
\end{document}
```

[在 Overleaf 中開啟這個 `setspace` Overleaf 中的範例。](https://www.overleaf.com/docs?engine=pdflatex\&snip_name=Example+use+of+the+doublespacing+command\&snip=%5Cdocumentclass%7Barticle%7D%0A%25+Choose+a+conveniently+small+page+size%0A%5Cusepackage%5Bpaperheight%3D18cm%2Cpaperwidth%3D14cm%2Ctextwidth%3D12cm%5D%7Bgeometry%7D%0A%25+Load+blindtext+package+for+dummy+text%0A%5Cusepackage%7Bblindtext%7D%0A%25+Load+the+setspace+package%0A%5Cusepackage%7Bsetspace%7D%0A%25+Using+%5Cdoublespacing+in+the+preamble+%0A%25+changes+the+text+to+double-line+spacing%0A%5Cdoublespacing%0A%5Cbegin%7Bdocument%7D%0A%5Cblindtext%5B1%5D%0A%5Cend%7Bdocument%7D)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/zh-tw/wen-yu-da/13-how-can-i-double-space-a-document.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
