OmniDocHow to update the Word table of contents, including updating only page numbers
Explain the two ways to update the Word table of contents: when the page numbers are misaligned, only the page numbers are updated; when the titles are added, deleted or changed, the entire table of contents is updated. Attached are updated steps, an updated checklist and frequently asked questions.
Key points of this article
- If the page number is misaligned after the main text is changed, just update the page number; if the title is added, deleted, renamed or leveled, the entire table of contents needs to be updated.
- The table of contents only collects paragraphs with heading styles applied. Ordinary bold or enlarged text will not be entered into the table of contents.
- Before updating, confirm that the directory is automatically generated. Manually entered directories cannot be refreshed through the update command.
- When the page number is offset as a whole, it is most likely that there is a problem with the section break or the starting value of the page number. You need to check these two places first.
- Refresh the table of contents once before finalizing, and check again after exporting, which can reduce rework.
After writing a paper or report, the page numbers in the table of contents often do not match the actual page numbers. After changing a few paragraphs of text and adding a picture, the page numbers of subsequent chapters moved backward as a whole. This article is written for people who use Word to write long documents. It explains how to update an existing table of contents. You can refresh the entries as a whole or just refresh the page numbers.
After reading, you will be able to judge which method to use in the current situation, know what to confirm before updating, and what items to check after updating. The operations in this article are based on the desktop version of Word.
How to update the Word table of contents? One sentence conclusion
Conclusion: If only the text content changes and the page number is misaligned, just update the page number; if the title is added or deleted or the title text or level is changed, the entire table of contents must be updated.
| your situation | Recommended practices | reason |
|---|---|---|
| Paragraphs have been added or deleted in the text, but the title text remains unchanged, but the page numbers are misplaced. | Only update page numbers | The entries remain unchanged, only the page where each title is located is recalculated, which is fast and the format will not be disrupted. |
| Chapter titles were added, deleted or renamed | Update entire directory | The entry itself needs to be added or deleted. Only the page number is updated and new titles cannot be added. |
| The title level has been changed, for example, the second-level title has been changed to the first-level title. | Update entire directory | The hierarchical indentation is determined by the title style and the entry needs to be regenerated. |
| The table of contents is manually entered text, not automatically generated. | Re-insert the automatic catalog and then update | Manual text will not change with the text, and the update command has no effect on it. |
| The first page numbers are all correct, only the last few chapters are wrong. | Check sectioning and page numbering settings first, then update page numbers | Usually the content is added in the middle, or the position of the section break changes, and it needs to be recalculated. |
Before you start: Confirm these points first
- Whether the title style is applied to the title. Word collects table of contents entries based on heading styles. If you only make the paragraph bold or enlarged, Word will not include it in the table of contents. Open the navigation pane, and the titles you can see are the titles that have the style applied. The paragraphs that do not appear need to be styled.
- Is the directory automatically generated? Click the directory. If the entire block is shaded in gray, it is usually an automatically generated directory and can be refreshed with the update command. If it is just ordinary text, the update command is invalid and needs to be deleted and reinserted.
- Whether the document is divided into sections or manually paginated. Section breaks will change the starting value and numbering method of page numbers. If section breaks are added before and after the table of contents, the page number may still be incorrect after refreshing, so confirm the section location first.
- Save a copy. Updating the table of contents will change the document content. If you have manually adjusted the text or format of the table of contents, the overall update will overwrite these changes. It is recommended to save another copy before finalizing it for easy return.
Steps to update the table of contents in Word (including updating page numbers only)
- Open the document that needs to be updated, confirm that the table of contents is located in the main text, and that the heading styles have been applied to headings at all levels.
- Right-click anywhere in the directory and find the update domain or update directory command in the pop-up menu.
- If only the page number has changed, select Update only the page number in the pop-up dialog box, and then confirm. Word will recalculate the page on which each entry is based on the current page break, and the entry text and formatting will remain unchanged.
- If additions, deletions, name changes, or heading level changes are made, select Update the entire table of contents. Word rescans heading styles to generate new entries, hierarchical indents, and page numbers.
- To refresh all fields in the document at once, including cross-references and figure numbers, press Ctrl+A to select the entire document, and then press F9. On Mac keyboards you usually need to press the Fn key at the same time. Note that this will update all fields, so be careful about manually modified content.
- After the update is completed, scroll through the level indentation and page numbers of the table of contents, and then proceed to the verification link below.
Check each item after completion
| Check items | How to see | What to do if there is a problem |
|---|---|---|
| Is the entry complete? | Check the navigation pane to see if each first-level and second-level title is in the table of contents | Missing title: Check whether it has a title style applied; More paragraphs: Remove the title style of the paragraph |
| Does the page number correspond? | Click on a few randomly and jump to the corresponding page to see if the title is on that page. | Overall misalignment: check the section break and page number starting value; only a few pages are missing: update the page number again |
| Level indentation | The first-level headings are in the top box, and the second-level headings are indented. | Wrong level: Modify the style level of the title and then update the entire table of contents |
| Prefix page number | Whether the abstract, table of contents and other pages use Roman numerals, and whether the main text starts with 1 | Wrong: In the page number settings of the footer, set the starting values for the prefix and the main text respectively. |
| The effect after exporting | Export to PDF and read the table of contents page numbers again | The page numbers are inconsistent after exporting: update the table of contents before exporting, and then export again. |

❓ Frequently Asked Questions (FAQ)
1. The page number is still wrong after updating the Word table of contents, what should I do?
First check whether there are section breaks or manual paging before and after the directory. If there are only errors in the later chapters, it is usually because content was added to the main text later, and the page numbers can be updated again. If the entire text is offset, check the starting page number of each section.
2. Why does the title I added not appear in the table of contents?
The table of contents only collects paragraphs that have heading styles applied. Apply the corresponding level heading style to the paragraph, and then update the entire table of contents.
3. What is the difference between updating only page numbers and updating the entire table of contents?
Only updating the page number will not change the entry text and level, which is suitable for situations where the page number is misplaced after the text is changed. Updating the entire table of contents will rescan the titles, which is suitable for titles that have been added, deleted, renamed or leveled, but manually modified table of contents text will be overwritten.
4. If I don’t have the desktop version of Word at hand, can I process it on the web?
.docx files can be opened for viewing and editing with the UniDoc web editor (app.unidoc.top), which supports Word-compatible editing. Whether the directory can be refreshed according to the above method depends on the actual opening result. It is recommended to keep the originals of important documents and check them again in local Word.
📝 Summary
Only the page number is updated when the page number is misaligned, and the entire table of contents is updated when the title is added, deleted or changed. Confirm the title style and section settings before updating, and check them item by item after updating. Developing the habit of refreshing the Word table of contents before finalizing can save a lot of rework time.
