Pick up any book that feels professional and authoritative in your hands. Now look at it carefully. Not the cover. The interior. The way the text sits on the page, the spacing between lines, the margin proportions, the chapter opening design, the running headers, the page number placement. None of those decisions happened by accident. Each one was made deliberately by someone who understood that formatting and design are not decoration. They are the infrastructure that makes reading effortless or exhausting.
Self-published books that look self-published almost always have the same underlying problem. The author treated formatting as a technical requirement to satisfy rather than a craft decision to make. They used default settings, made the obvious choices, and produced a book that works but does not feel right. Readers cannot always name what is wrong. They just stop reading.
If you need to hire professionals, we suggest using Writers of the West’s book formatting services handle print and ebook interiors together, ensuring that every typographic decision is consistent across formats and that the final files meet the technical specifications of KDP, IngramSpark, and other major distribution platforms. For authors who want the cover and interior to work as a unified design, Writers of the West’s book design services cover both elements under one brief, which is almost always the more efficient and more cohesive approach.
The Interior Font Decision Is Not a Minor Choice
Times New Roman is a manuscript font. It was designed for typewriters and word processors and it reads fine on screen. In a printed book, it is immediately recognisable as the default choice of someone who did not make a choice. The slight awkwardness in the letterforms, the weight distribution, all of it signals to the experienced reader that they are holding a document, not a book.
Garamond, Caslon, Palatino, Minion, Bembo. These are book fonts. They were designed specifically for printed pages and long-form reading. Their proportions, their spacing, their weight at 11 or 12 point across a full page of text, are calibrated for the reading experience in a way that Times New Roman simply is not.
This is not an expensive change. It is a free change that takes five minutes and makes the interior of the book feel completely different. Make it.
Line Spacing and Margins Are Where Amateurs Are Caught Immediately
Double-spaced text is for manuscripts submitted to editors and agents. Published books are not double-spaced. They use a line spacing between 1.2 and 1.5 times the point size of the font, calibrated for the specific font and the specific page dimensions. Too tight and the text feels claustrophobic. Too loose and the page feels empty and the book feels padded.
Margins are not just white space. They are breathing room, they are thumb space for the reader holding the book, and they are the frame that makes the text feel intentional. The inside margin of a bound book needs to be wider than the outside margin to account for the binding. Standard word processor margins applied to a book interior ignore this and produce pages where the text crowds into the spine and becomes uncomfortable to read.
Get the page dimensions right before you set your margins. A 6 x 9 book needs different margin ratios than a 5.5 x 8.5 book. Use the trim size to guide every interior measurement, not the word processor default.
Chapter Openings and Running Headers Signal Quality Immediately
The first page of each chapter is the single most designed element in a book’s interior. In traditionally published books, the chapter opening typically drops the first paragraph roughly one third of the way down the page, uses a slightly larger or differently weighted chapter number or title treatment, and begins the text below that. This convention exists because it gives the reader a moment of visual transition, a clear signal that something new is beginning.
Self-published books that use the same header design on chapter opening pages as they do on regular pages look unfinished. The running header, the author name and title or chapter title that appears at the top of each spread, should not appear on chapter opening pages at all. It should not appear on blank pages or on full-page images. These are typographic conventions that professional typesetters follow automatically and that authors working in Word or Google Docs almost never replicate.
Running headers should use a smaller point size than the body text, with adequate space between the header and the page text below it. They should be consistent across the entire book. Inconsistency in running headers is one of the clearest signals of self-published formatting to a reader who handles books regularly.
The Cover and Interior Have to Work as a System
The most common design mistake in self-publishing is treating the cover and the interior as two separate projects. The cover gets the most attention, the most budget, and the most design care. The interior is handled afterward, often by the author themselves in Word, using completely different aesthetic logic.
A book with a beautifully designed cover and a poorly formatted interior creates a specific kind of disappointment in the reader. The expectation set by the cover is not met by what is inside. That gap damages the author’s credibility in a way that is disproportionate to the formatting errors themselves.
The font choices, the color palette if there is one, the decorative elements in the chapter headings, the design of the title page, all of these should be in conversation with the cover rather than independent of it. This requires treating the book as a designed object from the beginning, not designing the cover first and formatting the interior second.
The Ebook Is Not the Same File as the Print Interior
This is one of the most common and most consequential formatting mistakes in self-publishing. Authors format a beautiful print interior and then upload the same file to Kindle. The result is a Kindle ebook with fixed fonts, fixed spacing, and design elements that break completely on devices with different screen sizes or reader-adjusted font settings.
Kindle uses reflowable text. The reader controls the font, the font size, and the line spacing on their device. Your carefully chosen Garamond at 11.5 point means nothing in that environment. The interior for Kindle needs to be built for reflowable text, with structural formatting applied through styles rather than direct formatting, and with all design elements that depend on fixed positioning removed or adapted.
Two files. Two different briefs. The print interior and the Kindle interior require different decisions, and treating them as the same project produces a Kindle file that looks like the print interior had an accident.
What Professional Formatting Actually Costs in Time and Money
Doing it yourself in Word or Google Docs is free in money and expensive in time and result quality. Learning to do it properly in professional typesetting software like InDesign or Affinity Publisher takes months of practice. Vellum on Mac produces clean ebook and basic print interiors efficiently once you understand its limitations.
Professional formatting services typically charge between $150 and $500 for a print interior depending on length and complexity, and a similar amount for a clean ebook file. For a book you have spent months or years writing, that investment in the final presentation is not extravagant. It is the last mile of a long journey and it is worth doing properly.
