Auto-Build a Table of Contents
A hand-typed table of contents rots the moment you edit page three. Word can build and update the TOC for you — but only if your headings use real heading styles instead of manual bold. This guide builds an auto-updating TOC in minutes and keeps it correct forever.

TL;DR / Quick Fix
Quick fix: format all headings with Heading 1, Heading 2 styles, place the cursor where the TOC goes, then References, Table of Contents, Automatic Table. Right-click the TOC and choose Update Field to refresh page numbers after edits. Never type a TOC by hand again.
Follow these steps
- Convert all headings to real styles first. Every chapter title must be Heading 1, every section Heading 2. The TOC reads styles, not bold text — manual formatting is invisible to it.
- Place the cursor where the TOC belongs. Usually a blank page after the title page. The TOC inserts as a field at the cursor position.
- Insert an automatic table of contents. Go to References, Table of Contents, and pick an Automatic Table. Word scans the document and builds the full TOC with page numbers instantly.
- Update it after every edit. Right-click the TOC and choose Update Field, then Update Entire Table. Page numbers and new headings refresh in one click.
- Customize which levels appear. Through the TOC dialog you can show just Heading 1 and 2, or drill down to Heading 3. Match the depth to the document's complexity.
- Style the TOC itself. The TOC has its own styles (TOC 1, TOC 2). Modify those to change fonts and spacing without touching your headings — the content stays linked.

What NOT to do
- Do not type page numbers by hand into a TOC. One edit invalidates them all — that is exactly the job the automatic TOC exists to do.
- Do not mix manual bold headings with styled ones. The unstyled ones silently vanish from the TOC.
- Do not forget to update before sending. A stale TOC with wrong page numbers looks worse than no TOC.
- Do not delete the TOC field to 'fix' it. Right-click, Update Field — deleting and retyping restarts the rot cycle.
Frequently asked questions
Why is my TOC empty?
Your headings are manually formatted, not styled. Apply Heading 1 and 2, then update the field.
Can the TOC include figure captions?
Yes — insert a separate Table of Figures from the References tab, built from caption styles.
How do I remove the TOC?
Select the whole TOC field and delete it. Your headings stay untouched — only the generated list goes away.
