How to Insert a Table of Contents in Word

The easiest way to insert a table of contents in Microsoft Word is to apply built-in Heading styles to your section titles, then choose References > Table of Contents > an Automatic Table. Word builds a linked contents list from those headings, and you can update it when the document changes.

Why Word needs heading styles

An automatic table of contents is based on the document’s structure, not simply on text that looks like a title. Making a line bold, larger, or centered does not necessarily tell Word that it is a heading. Applying a built-in style such as Heading 1 or Heading 2 does. Word can then identify the heading, include it in the contents list, and link the entry to its location in the document.

Think of Heading 1 as a main section, Heading 2 as a subsection, and Heading 3 as a smaller topic within that subsection. For example, a report might use Heading 1 for “Research Findings,” Heading 2 for “Survey Results,” and Heading 3 for “Responses by Age Group.” This hierarchy helps readers scan the contents and gives Word a reliable outline to use.

Heading styles also support Word’s Navigation pane and assistive technologies, so they are useful even when a document does not need a printed contents page. You can change how a heading style looks without removing its structural role: right-click the style in the Home tab’s Styles gallery, choose Modify, and adjust its formatting.

Insert an automatic table of contents

In Word for Microsoft 365 on Windows, use these steps:

Click in the document where the table of contents should appear. It usually goes after the title page and before the main text.
Apply Heading 1, Heading 2, and any lower-level heading styles to the relevant section titles. On the Home tab, select a heading, then choose the appropriate style from Styles.
Open the References tab and select Table of Contents.
Choose one of the Automatic Table options. Word inserts the contents list at the cursor.

The result contains entries based on the heading styles Word recognizes, typically with page numbers and links. The exact appearance depends on the selected built-in design and the document’s formatting. If you do not see a heading in the table, check that the text has a heading style rather than only direct formatting.

Word for Mac has the same basic process: apply heading styles, place the cursor, then use References > Table of Contents and choose an automatic option. Ribbon labels or layout can vary slightly by Word version. In Word for the web, the available table-of-contents controls may be more limited than in the desktop app; for fine-grained formatting, open the document in desktop Word.

Choose the right heading levels

Use heading levels consistently rather than choosing a style based on its visual size. A Heading 2 should be a subsection of a Heading 1, not a peer of it. Skipping levels—for example, jumping from Heading 1 directly to Heading 3—can make the document outline confusing and may produce an unexpectedly nested contents list.

Use Heading 1 for major chapters or primary sections.
Use Heading 2 for sections within a chapter.
Use Heading 3 only when a section genuinely needs another level of organization.

Not every short document needs every level. A two-page guide may be clear with Heading 1 alone, while a lengthy manual may need several levels. A contents page that lists too many tiny headings becomes harder to scan, so include enough detail to help readers navigate without reproducing every paragraph label.

Customize what appears and how it looks

Word’s built-in automatic tables are the quickest choice, but you can adjust the contents list. Go to References > Table of Contents and choose Custom Table of Contents to open options for page numbers, alignment, tab leaders, and the number of heading levels displayed. Tab leaders are the dotted or dashed lines that connect a heading to its page number. For example, a compact contents page might show only Heading 1 and Heading 2 entries, while a technical guide might show three levels.

To change the appearance of the entries, use the table-of-contents formatting options or modify the TOC styles, such as TOC 1 and TOC 2. These styles control the look of different levels in the list. This is preferable to manually changing individual entries, because direct edits may be replaced the next time Word updates the table.

You can also decide whether to show page numbers or make entries clickable. Clickable entries are useful in digital documents, while page numbers matter for printed copies. A table of contents can include both. If the document uses section breaks or unusual page numbering, check the finished result carefully to confirm that displayed numbers match the pages readers will see.

Update the table after editing

A table of contents is a field generated from the document’s headings. It does not always refresh immediately after you rename a section, add a heading, or change pagination. To update it, click inside the table and select Update Table or Update Field. Word usually offers two choices:

Update page numbers only: Use this when the headings and their order are unchanged, but page breaks or pagination have shifted.
Update entire table: Use this after adding, removing, renaming, or reorganizing headings. This refreshes the entries as well as page numbers.

When in doubt, update the entire table before sharing or printing. You can also right-click the table and choose Update Field. In a long document, make the update one of the final proofreading steps, after layout changes that might move text onto different pages.

Fix common table-of-contents problems

A heading is missing. Select the heading text and check the Home tab’s Styles gallery. Apply the right Heading style, then update the entire table. If the text uses a custom style, it may need to be mapped to a TOC level through Custom Table of Contents options.

Too many entries appear. Some body text may have accidentally been assigned a heading style, or the table may be set to display more levels than needed. Check the styles on the unwanted text and reduce the number of levels in the custom table settings.

The formatting changes after an update. This commonly happens when someone formats the generated entries directly. Modify the relevant TOC style instead, then update the table again. The generated contents should be treated as output, not as ordinary text to edit line by line.

Page numbers look wrong. Update the table after the document’s layout is final, and confirm that page numbering settings are correct. If the document has a cover page, section breaks, or page numbers that restart in later sections, inspect those settings as well as the contents list. The table reflects Word’s pagination; it cannot correct an incorrectly configured page-number scheme.

Clicking an entry does not navigate. Automatic tables are generally linked, but the way you follow a link can depend on Word’s settings. In many desktop configurations, Ctrl-clicking a TOC entry on Windows follows the link; on Mac, Command-click may be used. You can also right-click an entry and look for the link-following command.

Automatic versus manual contents lists

An automatic table is best for most reports, school assignments, proposals, manuals, and other documents that may change. It saves time, keeps page numbers current when refreshed, and can provide navigation links. A manual table is essentially ordinary text entered by the author. It may be appropriate for a short, fixed document with a deliberately unusual layout, but Word will not reliably rebuild its entries or page numbers when content moves.

There is also a useful distinction between a table of contents and a document outline. The outline is the hierarchy created by heading styles; the table of contents is a formatted display of selected levels from that hierarchy. You can have well-structured headings without inserting a contents page, and you can change the table’s presentation without changing the underlying section structure.

Frequently Asked Questions

How do I insert a table of contents in Word quickly?
Apply Heading styles to your section titles, click where the contents should go, then choose References > Table of Contents > an Automatic Table. Update the table after making structural or pagination changes.

Can Word make a table of contents automatically?
Yes. Word can create one from paragraphs formatted with heading styles. It can include selected heading levels, page numbers, and links, but it cannot infer a document’s structure reliably from bold or enlarged text alone.

How do I update a table of contents in Word?
Click inside the table and choose Update Table or Update Field. Pick Update page numbers only if the headings have not changed; choose Update entire table if you added, removed, renamed, or moved headings.

Why is my heading not showing in the table of contents?
It may be formatted as ordinary text rather than a heading style, or the table may be set to show fewer heading levels. Apply the appropriate Heading style, check the table’s level settings, and update the entire table.

Can I create a table of contents without page numbers?
Yes. Open References > Table of Contents > Custom Table of Contents and adjust the page-number option. You can also choose whether entries are clickable, which is particularly useful for a digital document.

Does a manual table of contents update itself?
No. A manually typed list is not connected to the document’s headings or pagination. Use an automatic table when the document is likely to change, or be prepared to revise every manual entry yourself.
