Word can format a manuscript into a book-like document, but it works best for short projects under 100 pages

Microsoft Word is built for letters and reports, not books. It can do the job for a short manuscript — a family history, a collection of essays, a self-published novella — but it will fight you on some tasks that book design requires. Word handles page numbering, headers, footers, and basic chapter breaks without trouble. It struggles with large tables of contents, cross-references that stay accurate through edits, and the kind of precise spacing that print-on-demand services expect. If your book is under 100 pages and you already own Word, it is worth trying. If you are writing something longer or plan to sell printed copies, a tool built for book layout — like Adobe InDesign or the free software Scribus — will save you hours of frustration.

The steps below assume you are starting a new project or have a draft ready to format. If you have already written your book in Word without these structures in place, you can still explore them — it just takes longer because you will need to go back and tag your chapters and sections.

Key Takeaways

  • Set up your page size, margins, and font before you write, because changing them later will shift your page breaks and chapter breaks throughout the document.
  • Use Word's built-in styles for headings and body text instead of manually formatting each paragraph, so that a table of contents can find and list your chapters automatically.
  • Create a new section for each chapter so you can restart page numbering, change headers, or adjust margins without affecting the rest of the book.
  • Word's table of contents feature reads your heading styles and builds a clickable list automatically, but it only updates if you tell it to.

Set up your document before you write a single word

Open a blank document and go to the Layout tab (or Page Layout in older versions). Set your page size first — for a printed book, standard options are 6 by 9 inches or 5.5 by 8.5 inches. For a document you plan to read on screen, leave it at 8.5 by 11 inches. Set your margins next. Books typically use 0.75 to 1 inch on all sides; screen documents often use 1 inch. Choose your font and size before you start writing. Word's default is Calibri 11 point, but books usually use a serif font like Garamond, Times New Roman, or Cambria at 11 or 12 point for readability. Change the line spacing to 1.5 or double-spaced if you plan to print and edit on paper, or leave it at single-spaced for a final document.

Save this formatted blank document as a template so you can reuse it for future projects. Go to File, click Save As, and choose Word Template from the file type dropdown. Name it something like "Book Template" and save it. The next time you start a book project, open this template instead of a blank document, and all your settings will already be in place. This saves you from repeating the same setup work every time you start writing.

Use styles to format chapters and headings automatically

Do not manually bold and enlarge your chapter titles. Instead, use Word's built-in styles. Highlight your first chapter title, then go to the Home tab and click Heading 1 from the styles gallery. Do the same for all chapter titles. If you have section headings within chapters, use Heading 2. For your body text, make sure it is formatted as Normal or Body Text. These styles are the foundation of everything that comes next — your table of contents, your headers, and your ability to change the look of all chapters at once.

If the built-in styles do not match what you want, modify them instead of creating new ones. Right-click on a style in the gallery, choose Modify, and change the font, size, color, spacing, or indentation. Every paragraph tagged with that style will update when ready. This is far faster than selecting and formatting each heading by hand, and it means you can change your mind about how chapters should look without touching the text itself. You can also create custom styles if you need something the built-in options do not offer, but start with the standard ones first.

Break your book into sections so chapters can start fresh

A section break lets you restart page numbering, change margins, or use different headers for different chapters. Place your cursor at the end of your first chapter (or at the beginning of your second chapter), go to the Layout tab, click Breaks, and choose Next Page. This creates a section break and starts your next chapter on a new page. Repeat this for each chapter. Section breaks are invisible in the final document but give you control over how each chapter looks.

Once you have sections, you can customize each one. For example, many books have no page number on the first page. To do this, go to the Insert tab, click Header & Footer, and check Different First Page. Now the first page of your document will have no header or footer, but all other pages will. If you want chapter titles to appear in the header, click inside the header area, type the chapter name, and it will appear on every page of that section. You can also set different margins for different sections if your book needs them.

Add page numbers and headers that match book conventions

Go to the Insert tab and click Page Number. Choose where you want the number to appear — bottom center is standard for books. Word will add page numbers to every page automatically. If you want page numbers to start at 1 on your first chapter instead of continuing from the introduction, place your cursor at the start of that chapter, go to Insert > Page Number > Format Page Numbers, and choose Start at with the number 1.

Headers and footers are optional but common in books. Many books put the book title on left-hand pages and the chapter title on right-hand pages. To set this up, go to Insert > Header, click Edit Header, and check Different Odd & Even Pages in the Design tab. Now you can type different text in the left-page header and the right-page header. This takes a few minutes to set up but looks professional and is expected in printed books. Once you have it right, you will not need to touch it again unless you change chapter names.

Build a table of contents from your heading styles

Once all your chapters are formatted with Heading 1 styles, Word can build a table of contents automatically. Place your cursor where you want the table of contents to appear — usually after your title page or introduction. Go to the References tab and click Table of Contents. Choose a style you like. Word will scan your document, find every paragraph tagged as Heading 1, and create a clickable list with page numbers.

If you add, delete, or rename chapters later, your table of contents will become outdated. Right-click on it and choose Update Field. Word will re-scan your document and fix the page numbers and chapter names. Do this before you print or send your book to anyone. Many readers use the table of contents to navigate, so keeping it accurate matters.

Export as PDF for printing or sharing

When your book is finished, save it as a PDF so the formatting stays exactly the same no matter what device opens it. Go to File > Save As, choose PDF from the file type dropdown, and save. A PDF preserves your fonts, spacing, page breaks, and headers exactly as they appear in Word. This is important because someone opening your Word file on a different computer might see different fonts or spacing if they do not have the same fonts installed.

If you plan to print your book through a print-on-demand service like Amazon KDP or IngramSpark, check their PDF requirements first. Most want a PDF with specific margin sizes, no bleeds (extra space for cutting), and fonts embedded. Word's PDF export handles this correctly for most services, but reading the service's guidelines takes five minutes and prevents rejection. Some services provide a checklist you can read before you export.

When Word is not enough for your book

Word hits its limits around 100 pages or when you need precise control over spacing and layout. If your book is longer, has many images, or needs to match professional print standards, consider Scribus (free, open-source) or Adobe InDesign (paid subscription). These tools are built for book design and handle large documents, image placement, and print specifications without the workarounds Word requires. They also make it easier to adjust spacing and alignment across many pages at once.

For very long books or complex layouts, the time you save by using the right tool is worth the learning curve. For a short family history or a self-published essay collection, Word works fine if you follow the steps above and do not try to force it into design work it was not built for. The key is knowing your book's size and complexity before you choose your tool.

Frequently Asked Questions

Can I use Word to write a book that will be printed and sold?

Yes, if it is under 100 pages. Export it as a PDF and upload it to a print-on-demand service like Amazon KDP or IngramSpark. Check their PDF requirements first — most want specific margins and embedded fonts, which Word's PDF export provides by default. For longer books or books with many images, a dedicated layout tool will give you more control and fewer headaches.

How do I keep my page numbers from appearing on chapter title pages?

Check Different First Page in the Design tab of the header and footer area. This removes the page number (and any header) from the first page of your document. If you want to remove it from every chapter's first page, you will need to create a section break at the start of each chapter and repeat this setting for each section.

What happens if I change my margins after I have written the whole book?

Word will reflow your text and shift all your page breaks. Your chapter breaks may no longer land where you want them, and your table of contents page numbers will be wrong. This is why setting up margins, font, and page size before you write is important. If you must change them, update your table of contents afterward by right-clicking it and choosing Update Field.

Can Word handle a book with images?

Word can place images, but it does not handle them as precisely as a layout tool does. For a book with many images or images that need to be positioned exactly, Scribus or InDesign will give you better control. For a book with a few images scattered through the text, Word works fine — just insert them, right-click, choose Wrap Text, and position them where you want.

Do I need to buy Microsoft Word to make a book?

No. Google Docs (free, online) and LibreOffice Writer (free, downloadable) can both do the tasks described here. Google Docs is simpler but has fewer formatting options. LibreOffice Writer is closer to Word and handles complex documents better. Both can export as PDF. If you already own Word, use it. If you do not, either of these free options will work.
