Reflowable Vs. Fixed-Layout eBooks

There are two main formats in eBook editions: standard/reflowable and fixed-layout or print replica.

A reflowable eBook cannot replicate your print edition design. This can be supported by fixed-layout eBooks only.


It supports enhanced designs. However, it may be not supported by old devices or accepted by all retailers and distributors. They are supported by Amazon (KPF files) and Apple/iTunes (ePub 3). Amazon calls this format “Print Replica” and indicates on each product page a list of compatible devices. It is recommended for books with complex layouts, illustrations, images, or interactive elements (e.g., children or comic books, cookbooks, architecture books, etc.).

Recommended input files for fixed-layout ebook production: Word, txt, RTF, ODT, pages, PDF, InDesign.
