Ebook, print, or both?

Most authors decide this by asking which sells better, which is the wrong first question. The formats differ in something more basic than sales: who controls the page.

In a print book, you do. You decide the trim size, the margins, where every chapter falls, and what the reader holds. In a reflowable ebook, the reader does. They pick the typeface size, and the text reflows to fit a phone, an e-ink screen or a tablet held sideways.

Almost everything else follows from that.

What the difference actually costs you

	Print	Reflowable ebook
Pages	Fixed, yours	None — computed on the device
Type size	Yours	The reader’s
Trim size	A decision	Meaningless
Margins	Enforced by the printer	The reading app’s
Page breaks	Yours to control	Not yours
Images	Placed exactly	Between paragraphs
Cover	One flat sheet, needs the page count	A front-facing image
Production cost	Per copy, per page	None
Minimum length	18–24 pages, by printer	None

The row that catches people is images. In print you place an image beside a paragraph. In a reflowable ebook there is no “beside”, because there is no page — the image lands between paragraphs and the text continues underneath.

A reflowable ebook is not a book with the pages removed. It is a different medium that happens to carry the same words.

Which to start with

Start with the ebook if you want to publish quickly, you are testing whether the book finds readers, your genre skews digital, or the budget is thin. There is no printing cost, no spine arithmetic, no paper decision, and no cover that has to wait for a final page count.

Start with print if the layout carries meaning. Cookbooks, workbooks, textbooks, poetry with deliberate line breaks, anything with tables or diagrams. These are books where reflowing the text damages the content rather than merely relocating it.

Do both, eventually, in most cases. They reach different readers and there is little evidence of one meaningfully eating the other. The practical order is usually ebook first, print once the text is genuinely final — because the print cover depends on the page count, which depends on the interior being finished.

Do not convert a PDF into an ebook

This is the single most common expensive mistake in the whole process.

A print PDF is a description of ink on fixed pages. It knows where every character sits and it no longer knows what any of them are — the chapter headings are not chapter headings any more, they are large text at a coordinate. Converting that into an EPUB produces exactly what you would expect: no working navigation, broken paragraphs, page numbers stranded mid-sentence, and headers repeating inside the text.

Both formats should come from the same source manuscript, one that records what each part of the book is. From there, print and ebook are two projections of one structure. That is also what keeps them saying the same thing: a chapter added to one cannot be missing from the other.

Fixed-layout is a narrow tool

There is a third option: a fixed-layout EPUB, which keeps a designed page rather than reflowing.

It is correct for children’s picture books, comics, graphic novels and heavily illustrated titles where the layout is the content. It is wrong for ordinary prose, because the reader cannot change the type size, accessibility is markedly poorer, and distribution is narrower.

If your book is words in paragraphs, it is reflowable. The exceptions are genuinely exceptions.

What each format demands of the manuscript

For print, you need decisions you can skip entirely in an ebook: a trim size, margins that account for the binding, where chapters open, what happens at a page break. Those are covered in formatting for KDP and the print-ready PDF checklist.

For the ebook, you need structure rather than layout: heading styles that say what things are, alt text on every image, no manual page breaks, no fixed body type size. Those are covered in Word to EPUB.

The overlap between those two lists is small, which is why a manuscript prepared for one is rarely ready for the other — unless it was prepared as structure in the first place, in which case it is ready for both.

The decision, briefly

1. Words in paragraphs? Reflowable ebook, plus print if you want the object.
2. Layout carries meaning? Print first, and consider fixed-layout for the ebook.
3. Testing the market, or short on budget? Ebook first.
4. Either way, work from one source manuscript and export both. Never convert the PDF.

The formats stop competing once you stop treating them as two versions of one file. They are two outputs of one book, and the only real question is which you release first.

In Nueel the manuscript is a structured document rather than a layout, and the print PDF and the EPUB are both projections of it. The design decisions that only make sense on a page stay on the page, and the structure both formats need is written once.

Common questions

Should I publish an ebook, a print book, or both?

Both is the usual answer, because they reach different readers and neither cannibalises the other much. Start with the ebook if you want to publish quickly and cheaply, since there is no cover spine to calculate and no printing cost. Start with print if your book depends on layout, such as a cookbook, workbook or anything with tables and diagrams.

What is the real difference between an ebook and a print book?

A print book has fixed pages that you control completely. A reflowable ebook has no pages at all: the reader chooses the typeface size, and the text reflows to fit whatever screen they are holding. Every layout decision that depends on knowing where a page ends is meaningless in a reflowable ebook.

Does an ebook cost anything to produce?

Beyond your time, essentially nothing. There is no printing cost, no spine to calculate, no paper choice, and no minimum page count. This is why an ebook-first release is the cheapest way to publish, and why an author testing whether a book finds readers usually starts there.

Can I use the same file for both?

Not the same output file, but you should work from the same source. A print book exports as a PDF with fixed pages; an ebook exports as an EPUB that reflows. Producing them from one manuscript is what keeps them consistent. Converting a finished print PDF into an ebook is the route that goes badly, because a PDF has already thrown away the structure the ebook needs.

What is a fixed-layout ebook?

An ebook that keeps a fixed page design rather than reflowing, used for children's picture books, comics and heavily illustrated titles where the layout is the content. It is legitimate but limited: readers cannot change the type size, accessibility is poorer, and distribution is narrower. For ordinary prose it is the wrong choice.

Which sells more, ebook or paperback?

It varies so much by genre that a general figure would mislead you. Romance, science fiction and thrillers skew heavily to ebook; literary fiction, cookbooks, children's books and gifts skew to print. Look at the format mix of books like yours rather than at an overall market average.

Do I need a different cover for each?

Yes, and they are very different objects. An ebook cover is a single front-facing image. A print cover is one flat sheet carrying back, spine and front together, with bleed, and its width depends on the final page count. The ebook cover can be made any time; the print cover cannot be finished until the interior is.
