How to Format a Book for Self-Publishing

You've written your novel, polished your prose, and decided to self-publish. Congratulations! Now comes a step many indie authors underestimate: formatting. How your story looks on the page (or screen) matters enormously. A poorly formatted book full of spacing glitches, cramped margins, and inconsistent fonts creates a jarring reader experience, which can lead to negative reviews and even lost sales.

The good news is that self-publishing formatting is entirely learnable, and the tools available today make it more accessible than ever. In this post, we'll walk through everything you need to know to format your book for both ebooks and print, so your book looks professional and enticing to readers!

Why does book formatting matter?

How your manuscript looks on the page is a critical part of the reader experience. When it's done well, your reader shouldn't notice it at all. Good formatting is invisible. It quietly carries the reader from sentence to sentence, chapter to chapter, while their attention stays fully on the story. The moment formatting does become visible, you've pulled them out of the fictional dream you worked so hard to build.

And readers will notice inconsistencies, even if they can't articulate why something feels off. An unexpected font shift, an oddly indented passage, or strange spacing between paragraphs all raise quiet questions: Did we just switch POV? Is this internal monologue now? Is this formatting choice intentional? Am I supposed to be picking up on something here? Every one of those questions is a small tax on the reader's immersion, and enough of them add up to a frustrated reader, a one-star review, or a book they never finish.

How to format a book for self-publishing

Self-published authors typically need to prepare their manuscript in two distinct formats: ebooks and print. Each has different requirements, different constraints, and different tools.

Understanding the difference between the two before you start will save you a lot of rework:

• Ebooks are reflowable documents. Readers can adjust font size, style, and screen brightness on their devices, which means you have less control over the final appearance. Clean, simple formatting is essential.
• Print books have fixed layouts. Every choice about margins, fonts, spacing, and page size is locked in and will look exactly the same for every reader. You have more control and more decisions to make.

Most authors need both types of book, so let's look at each in turn.

Formatting an ebook

The Golden Rule: Keep it simple!

Ebook formatting rewards simplicity. Complex layouts, such as multiple font styles, elaborate headers and footers, tables, or intricate designs, often break during conversion from Word or InDesign to ePub or Kindle formats. The more complicated your formatting, the more likely something will look wrong on a reader's device. Stick to the essentials, and your ebook will render cleanly across platforms.

Fonts

Most digital platforms apply their own default fonts, and readers can change them on their devices anyway. Rather than manually formatting your text with a specific typeface, use your word processor's built-in paragraph styles: Normal for body text, Heading 1 for chapter titles, and so on. This makes conversion to ebook formats significantly cleaner and more reliable.

Paragraph spacing and indents

Use first-line indents for body text (0.5 inches, set in your paragraph styles, not with the Tab key). Remove any extra space between paragraphs. While blogs, emails, and web content typically use block paragraphs with space between them, e-readers handle spacing differently, and extra paragraph spacing can create an inconsistent reading experience across devices.

Chapter breaks

Insert a proper page break before each new chapter. This is found under Insert > Break in most word processors. Do not simulate a chapter break by hitting Enter multiple times. A true page break ensures each chapter starts fresh, regardless of the reader's font size setting on their device.

Scene breaks

Use a centered "#" or "* * *" to mark scene breaks within chapters. These symbols translate cleanly and signal to readers that a shift in time, location, or point of view has occurred.

Chapter headings and styles

Apply your word processor's Heading 1 style to all chapter titles and Heading 2 to any subheadings. This does two important things: it creates a consistent visual hierarchy in your book, and it automatically generates a clickable table of contents, which most platforms require or strongly recommend.

Images

Simple images like author photos, chapter ornaments, and section dividers generally work well in ebooks as long as they're high resolution (at least 300 dpi). Avoid complex layouts that incorporate images alongside text, as these rarely translate well across devices and screen sizes.

Conversion and Formatting Tools

Microsoft Word files can be uploaded directly to most platforms, but the results are often imperfect. Dedicated formatting software can produce significantly cleaner ebooks:

• Vellum (Mac only): widely considered the gold standard for ease of use and beautiful output; produces both digital and print files
• Atticus (Windows and Mac): a strong Vellum alternative that works on both platforms
• Scrivener: popular writing software with solid export capabilities
• Kindle Create: Amazon's free tool for formatting Kindle files specifically

These tools often include useful built-in templates that can save you time in the publishing process. Most major self-publishing platforms also accept ePub files, which the above tools can generate.

Print formatting

Start with trim size

When formatting your print book, first choose your trim size—the physical dimensions of your finished book. This choice affects everything else, including how your book feels in a reader's hands. Common trim sizes for fiction include 5 x 8 inches, 5.5 x 8.5 inches, or 6 x 9 inches.

Check your chosen print platform's available sizes before you commit. Amazon KDP Print and IngramSpark both publish lists of their available sizes, and your margin requirements will depend on your trim size and page count.

Fonts

Unlike manuscripts and ebooks, print gives you real control over typesetting. The fonts you choose contribute significantly to how professional your book looks and feels.

For the body, choose a serif font designed for long-form reading. While Times New Roman is the industry standard for manuscripts, popular typefaces for self-published books include:

• Garamond: elegant and traditional
• Caslon: a classic book typeface that's easy to read
• Palatino: slightly larger on the page, good for books aimed at older readers
• Georgia: a screen-optimized serif that also works well in print

Text is typically set at 10-12 points, depending on the font and trim size. When in doubt, print a sample page and read it in natural light.

Margins

You need to account for the **gutter (**the inner margin where pages meet the spine), which must be wider than the outer margins to ensure text isn't swallowed by the binding.

The required gutter width depends on how long your book is: thicker books need wider gutters because pages curve more sharply near the spine. Both Amazon KDP Print and IngramSpark publish detailed guidelines based on trim size and number of pages. Follow these carefully! Incorrect margins are one of the most common reasons print files are rejected during upload.

Typical ranges for a standard novel:

• Gutter (inner margin): 0.75 to 1 inch, depending on page count
• Outer margin: 0.5 to 0.75 inches
• Top and bottom margins: 0.75 to 1 inch

Line spacing

Print books use tighter line spacing than manuscript format. Rather than double-spacing, set your line spacing to approximately 1.2 to 1.5 times the font size, set as "exactly" or "multiple" in your word processor's paragraph settings. This gives the page a clean, professional book-like feel. The exact setting varies with your font and trim size, so print a sample page to check readability before finalizing.

Chapter openings

In traditionally designed books, chapters begin on a "recto page", a right-hand, odd-numbered page. This creates visual consistency and feels professional to readers accustomed to traditionally published books. Most formatting tools handle this automatically when you insert the correct type of break, but it's worth verifying in your final proof.

Chapter opening pages traditionally have no running header, and the chapter title or number typically appears several lines below the top of the page, giving the first lines a sense of visual space. A new chapter might also begin with a drop cap, a large decorative capital letter at the beginning of the first paragraph.

Running headers and page numbers

Running headers used in print books typically display the author name on the left-hand (verso) page and the book title on the right-hand (recto) page, with page numbers in the header or footer. Chapter opening pages, the title page, and any front matter pages (copyright, dedication, table of contents) traditionally have no header.

Front and back matter

Printed books include standard elements beyond the manuscript text itself. At a minimum, plan to include:

Front matter:

• Title page
• Copyright page (this is where your copyright notice, ISBN, and edition information live. This is essential in a published book)
• Dedication (optional)
• Table of contents (optional for fiction, but useful for nonfiction)

Back matter:

• Acknowledgments (optional)
• About the Author
• Also By (if you have other books)
• A note asking readers to leave a review

Formatting tools for print

The same tools that handle digital formatting also handle print:

• Vellum and Atticus both produce print-ready PDFs alongside digital files
• Adobe InDesign is the professional industry standard and offers the most control, but has a steep learning curve and subscription cost
• Microsoft Word can produce acceptable print files with careful setup, but results vary

Many indie authors handle their own digital formatting but hire a professional book formatter for print, particularly for their first book. The investment is usually modest, and the results are noticeably more polished.

Proofing your formatted book design

Before you hit publish on any platform, order a physical proof copy of your book. Reading your book in its final printed form reveals formatting issues, such as widows and orphans, awkward indentations, headers that bleed too close to text, that are nearly impossible to catch on screen. Most print platforms offer proof copies at cost, and it's one of the best investments you can make before your book goes live.

For digital files, preview your file on actual devices! Check it on an e-reader, a phone, and a tablet, if possible. Pay attention to how chapter breaks, scene breaks, and any special elements render across different screen sizes and settings.

Ready to publish your ebook or print book?

Formatting is the last invisible layer between your manuscript and your readers, and when it's done well, they'll never think about it once. They'll just read. Take the time to get it right. Use the right tools for the job, and order a proof before you publish. Your story deserves to look as good as it reads!
