# What is a reflowable ebook?

A reflowable ebook has no fixed pages. Its text rearranges itself to fit the screen and the type size the reader picks, so one file reads well on a phone, a tablet and an e-reader. KDP says its eBooks are reflowable by default.

## What it means in practice

The reader sets the type size and the screen sets the line length, so you cannot control where a line or a page ends. A running head, a page number on a contents page, or two pictures placed side by side on a spread will not survive the way they do in print.

That suits text that reads straight through. It suits a coloring page or a worksheet badly, because those depend on the page itself. The alternative is a [fixed layout](/glossary/fixed-layout/).

## How Chapbook uses it

Chapbook's [EPUB 3](/glossary/epub/) is reflowable, with a navigable table of contents. The digital PDF of the same book keeps fixed pages, so you can offer each reader the one that suits their device, as [PDF vs EPUB](/guides/pdf-vs-epub/) explains.

An activity pack has no EPUB at all, because a reflowable coloring page is no use to anyone. To see the difference, download both files of the sample on this page, then open the EPUB in a reading app and change the type size.

## Made with Chapbook: The Pricing Playbook

The Pricing Playbook: How founders set a price they can defend, by Jane Founder. Nonfiction book, 9,862 words, 43 pages. A sample generated from one brief and exported unedited; it is not a customer's book. Read every page: https://chapbook.ink/examples/nonfiction/

The brief:

> A repeatable method for pricing software: customer interviews, a value metric, tiering, and setting numbers you can defend. Promise: A repeatable method for setting a price you can defend to customers, investors and yourself, validated by ten customer interviews in a week. Reader: A founder who priced by guessing or by copying a competitor and now has to defend or change the number. Voice: Direct second person with occasional first person; worked examples with fictional companies; tables where they clarify; no invented statistics or named studies: reason from mechanics and examples.

## Questions

### Does a reflowable ebook have page numbers?

Not fixed ones. The number of screens depends on the device and the type size the reader chose, so a page in one reader's view is not a page in another's.

### Is a Chapbook EPUB reflowable?

Yes, always. Chapbook does not make a fixed-layout EPUB. For pages that must stay exactly as typeset, use the PDF.
