Print book paragraph formatting follows two main conventions: indent the first line of each new paragraph, but leave the opening paragraph of every chapter flush left; and set the body text justified so both edges line up. Use your software’s built-in indent setting, never the Tab key.

Should the First Paragraph of a Chapter Be Indented?
No. The first paragraph of a chapter is set flush left, with no indent. Every paragraph after it gets a first-line indent. This is the standard you will see in almost every professionally typeset book, and the Chicago Manual of Style treats it as the default for book interiors.
The reason is simple once you picture it. An indent exists to show the reader that a new paragraph has started. The first paragraph after a chapter title has nothing above it to separate from; there is already a big visual break and white space. It may also carry a drop cap or other special treatment. Adding an indent in this case would mark a break that the layout has already made, so designers leave it out.
The same flush-left treatment applies to the first paragraph after a scene break (the little gap or row of asterisks between scenes) and the first paragraph after a subheading. In each case, something above the paragraph has already signalled a fresh start, so an indent would be doing a job that is already done.
Paragraphs after a block quote or a list are a different case, and here the choice is about meaning rather than a fixed rule. If the text after the quote or list continues the same thought as the paragraph that introduced it, set it flush left; if it starts a new point, give it the normal first-line indent. Running this text flush left every time is really a self-publishing shortcut from the CreateSpace era; in practice, the indent after quotes and lists is one of the things authors most often ask to have put back.
How Wide Should a Paragraph Indent Be?
A first-line indent should be small. The traditional measure is one em, which is the width of a capital M in your chosen type and, in practice, roughly the same as the font size; for a 12-point font that is about 0.17″. Typographer Matthew Butterick’s Practical Typography puts the workable range at one to four times the point size. The KDP default, inherited from the CreateSpace days, is a slightly wider 0.25″ (18 points), which is also perfectly fine.
What you want to avoid is the half-inch indent that Microsoft Word inserts when you press Tab. That measure is a leftover from typewriters, and on a narrow book page it pushes the first word so far in that it reads as a gap rather than a cue. In Word, set the indent through the Paragraph dialog instead: under Indentation, choose Special, then First line, and enter your measurement. Better still, build it into a paragraph style so every body paragraph indents by the same amount and you can adjust them all at once. Keep the indent in step with your line spacing, since the two work together to set how dense the page feels.
Dedicated book-formatting tools take this off your hands: Vellum and Atticus build a correct first-line indent into their templates, so the first paragraph of each section is left flush and the rest are indented without you setting anything.
Should a Print Book Be Justified or Left-Aligned?
For a finished print book interior, justified text is the traditional choice. Justified means both the left and right edges of the text block are straight, with the spacing between words stretched slightly so every full line reaches the right margin. This is the look the Alliance of Independent Authors lists among its standard typesetting conventions, and it is what most readers unconsciously expect a book to look like.
The alternative is left-aligned text, also called ragged right, where the left edge is straight and the right edge ends unevenly. Ragged right is the correct setting for a manuscript you are sending to an editor, because the even word spacing is easy to read and mark up. Some authors keep it for the final book too, particularly for accessibility, since a steady left edge and consistent word spacing can be easier for some readers. Ragged right also goes hand in hand with not breaking words: because the lines never have to reach the right margin, there is no need for end-of-line hyphenation. Justified text is the opposite, relying on hyphenation to keep its spacing even, which is a readability trade-off we look at in the next section.
A few specific situations call for ragged right even inside an otherwise justified book: very short line lengths, such as the narrow columns of a two-column layout, where justifying would force ugly gaps between words; and reference lists or bibliographies full of long web addresses, where justified spacing stretches the lines awkwardly. For the running text of most books, though, justified is what readers expect. One point of confusion is worth clearing up: the alignment in your editing manuscript does not have to match your final book. Keep the manuscript ragged right for editing and switch to justified, if you want it, when you set up the interior. If you are still choosing your page size, our guide to page margins for print-on-demand books covers how the text block sits inside the page.
Why Justified Text Needs Hyphenation Turned On
If you justify your text, turn hyphenation on. Justification works by adding tiny amounts of space between words so each line fills the full width. When a long word will not fit, the software either crams the remaining words together or spreads them far apart, and over several lines those gaps can line up into distracting vertical channels of white space called rivers.
Hyphenation solves this. By allowing a long word to break across two lines, it gives the software more room to even out the spacing, so you get tidy lines instead of loose ones. This is why hyphenation and justification are handled together in professional layout tools; you rarely want one without the other.
Justified text with hyphenation switched off is one of the clearest signs of a do-it-yourself layout, and it is easy to miss on screen because the gaps only become obvious once the page is full. If you would rather avoid hyphens altogether, that is a fair reason to choose ragged right instead, since left-aligned text keeps even word spacing without needing to break words at all. But be aware that this is not what most readers expect for the text in a formatted book.
Indented Paragraphs or Block Paragraphs: Which to Use?
There are two ways to show where a new paragraph begins: a first-line indent with no extra space between paragraphs, or a block style with a clear line of space between paragraphs and no indent. Each method does the job on its own, so a book should use one or the other rather than combining an indent with a gap.
Fiction almost always uses the indented style: paragraphs flow one after another, separated only by the indent, which keeps the page looking continuous and book-like. Most narrative non-fiction books and memoirs follow the same convention.
Block paragraphs (the style you are reading on this web page) suit some non-fiction, such as business books, manuals, and reference works, where short separated chunks help readers scan and jump around. Block style is also the norm for documents read on screens. For a traditional print book that is meant to be read start to finish, the indented style is the safer default.
Print Book Paragraph Formatting in Ebooks vs Print
Ebooks follow the same first-paragraph rule as print, but the way you set indents is different, and you hand more control to the reader. In a reflowable ebook (the kind that lets readers change the font and text size), you should not lock the body text to fixed measurements. Amazon’s Kindle text guidelines for reflowable books ask that body paragraphs be left near their defaults so the reader’s own settings, including their preferred alignment, are respected, and that any indent be set as a relative size rather than a fixed one.
That single change in mindset, designing for a screen you cannot predict, is the heart of the difference between print and ebook layout. The print page is fixed; the ebook page is not.
There is one rule that holds in both formats, and it is the most useful practical tip in this article: set your indent with the paragraph indent setting in your software, not with the Tab key or a row of spaces. A tab is honoured when Word makes a print PDF, so it does no harm there; but an ebook has no concept of a tab, so when the file is converted to EPUB the tab is simply dropped and that paragraph loses its indent. Manual spaces are just as unreliable. A first-line indent built into the paragraph style carries cleanly into both print and ebook. If you also use running headers and page numbers, the same principle applies: let the software place them, rather than typing them in.
Frequently Asked Questions
Should the first paragraph of every chapter be indented?
No. The first paragraph of a chapter, and the first paragraph after any scene break or subheading, is set flush left with no indent. Only the paragraphs that follow are indented. The indent marks a new paragraph, and the first one already has a clear break above it.
How big should a paragraph indent be in a book?
About one em, the width of a capital M, which works out to roughly the font size (around 0.17″ for 12-point type). KDP’s 0.25″ default is also fine. Avoid Word’s 0.5″ Tab default, which is too deep for a book page and reads as a gap.
Is it OK to have a space between paragraphs in a novel?
Not usually. Novels use a first-line indent with no extra space between paragraphs. Block paragraphs with a line of space between them are a non-fiction and on-screen style. The key rule either way is to use one method, never both at once.
Do ebook paragraphs follow the same rules as print?
The first-paragraph flush-left rule is the same, but indents in a reflowable ebook should be set as relative sizes, not fixed measurements, and body text should stay near its defaults so the reader’s own font and alignment choices apply. Justification in an ebook is largely controlled by the reader’s device.
Why shouldn’t I use the Tab key to indent paragraphs?
A tab is fine for a print PDF, but ebooks have no concept of a tab, so it is dropped when the file is converted to EPUB and the line loses its indent. Manual spaces are just as unreliable. Set a first-line indent in your paragraph style instead; it applies to every paragraph automatically and carries cleanly into both print and ebook.
Paragraph formatting is one of the smallest parts of a book to set up and one of the easiest to get visibly wrong. Indent every paragraph except the first of each section, keep the indent shallow, pick either indents or spacing rather than both, and if you justify your text, leave hyphenation on. Set it once in your paragraph styles and the same choices will carry through to both your print and ebook editions.
