如果您正在创建Word文档并希望添加装订线边距，您可能会摸不着头脑。什么是天沟边距？天沟边距位置在哪里？我真的需要排水沟边距吗？您有问题，我们有答案。
我们将引导您了解有关Microsoft Word中装订线边距所需了解的所有信息。
Word 中的装订线边距是什么？
装订线边距是文档左侧、顶部或内部页边距之外的空间。其目的是为装订文档（例如实体书籍、手册或类似印刷材料）提供额外的空间。
添加的空间可确保您的内容保持完整，并为装订提供足够的空间。
天沟边距尺寸和位置
要确定装订线边距的尺寸，请咨询将装订文档的服务，因为它可能会因公司或页数而异。如果您自己动手，则平均装订线边距为 0.5 英寸。
虽然您可以在Word(Word)中设置所需的装订线边距大小，但只有在使用“普通(Normal)页面”设置时才能选择其位置。这允许您选择左侧或顶部的装订线边距。
如果您使用“镜像边距” 、“(Mirror Margins)每张(Sheet)2 页”或“书本折叠”(Book Fold)设置，您仍然可以添加装订线边距尺寸，但默认情况下位置位于左侧或内部。您还会注意到这些文档类型的装订线(Gutter)位置设置呈灰色。
天沟边距特征
Windows和Mac上的(Mac)Word桌面应用程序中提供了装订线边距功能。虽然Word网页版和Word移动应用程序支持该功能（如果您在桌面上添加该功能），但它们不提供添加或调整装订线边距的功能。
什么时候需要装订线边距？
如前所述，您应该对书籍、手册、小册子(booklets)、目录和相关材料等
装订的印刷项目使用装订线边距。
如果您计划使用环装订、螺旋装订、梳式装订或类似装订方法打印(plan to print)和装订文档，您还可以添加装订线边距。您通常会看到以这种方式装订的培训材料、学习资源、作品集和法律文件等项目。
最重要的是，对于您计划装订的任何文档，您应该添加装订线边距。
如何在Word中添加装订线边距
您可以以相同的方式
在Windows和Mac上的(Mac)Word桌面应用程序中添加装订线边距。
- 在Word(Word)中打开文档后，转到“布局”选项(Layout)卡。

- 当您进行调整时，您将在Windows上的底部附近和Mac上的右侧看到预览(Preview)。装订线边距以黑白方格图案显示。

Gutter Margin/Position in Microsoft Word: All You Need to Know
If you’re creating a Word document and wish to add а gutter margin, you might be scratching your hеаd. What’s a gutter margin? Where’s thе gutter margin position? Do I really need a gutter margin? You hаνe questions, we have answers.
We’ll walk you through everything you need to know about gutter margins in Microsoft Word.
What Is a Gutter Margin in Word?
A gutter margin is the space outside of the page margin on the left, top, or inside of the document. Its purpose is to provide extra space for binding documents such as physical books, manuals, or similar printed materials.
This added space ensures that your content remains intact with enough room for the binding.
Gutter Margin Size and Position
To determine the size for the gutter margin, check with the service that will bind the document as it may vary by company or the number of pages. If you’re doing it yourself, 0.5 inches is the average gutter margin.
While you can set the gutter margin size you need in Word, you can only choose its position when you use the Normal page setting. This allows you to pick the left or top for the gutter margin.
If you use the Mirror Margins, 2 Pages per Sheet, or Book Fold setting, you can still add the gutter margin size, but the position is on the left or inside by default. You’ll also notice that the Gutter position setting is grayed out for these document types.
Gutter Margin Feature
The gutter margin feature is available in the Word desktop application on Windows and Mac. While Word on the web and the Word mobile apps support the feature if you add it on the desktop, they do not provide the ability to add or adjust gutter margins.
When Do You Need a Gutter Margin?
As mentioned, you should use a gutter margin for printed items that are bound like books, manuals, booklets, catalogs, and related materials.
You may also add a gutter margin if you plan to print and bind the document using a ring, spiral, comb, or similar binding method. You typically see items such as training materials, study resources, portfolios, and legal documents bound this way.
The bottom line is that for any document you plan to bind, you should add a gutter margin.
How to Add a Gutter Margin in Word
You can add a gutter margin in the Word desktop application on Windows and Mac the same way.
- With your document open in Word, go to the Layout tab.
- Select the Margins drop-down menu in the Page Setup group and choose Custom Margins at the bottom.
- In the Page Setup dialog box, confirm you’re on the Margins tab.
- Use the Gutter setting in the Margins section to set the size for the gutter margin.
- If you’re using Normal in the Multiple Pages drop-down menu, you can also choose the Gutter position. Pick from Left or Top.
- As you make your adjustments, you’ll see the Preview near the bottom on Windows and the right side on Mac. The gutter margin displays in a black and white checkered pattern.
- Select OK when you finish.
When you return to your document, you’ll notice the addition of the gutter margin outside the margin.
In the screenshot below, you can see our document before (left) and after (right) adding a top gutter margin. You’ll notice extra space above the Header section, or top margin.
Remove a Gutter Margin Word
If you need to remove the gutter margin after you add it, this is easy by returning to the margin settings.
Head back to the Layout tab, open the Margins drop-down menu, and pick Custom Margins. In the Page Setup box, set the Gutter size to “0” and select OK to save the change.
To make sure your printed document is easy to read and the words aren’t too close to the binding, simply add a gutter margin in Word. For more help with your document, look at how to insert page numbers in Word as well as in Google Docs.
