Interior Book Files: The Hidden KDP Formatting Mistakes Most Authors Make
Many self-publishing authors believe uploading a manuscript to Amazon KDP is simple. In reality, the biggest problems often come from poorly prepared interior book files. While KDP accepts Word documents and PDFs, it does not ensure your formatting is technically correct for print or ebook publishing. Issues such as incorrect margins, broken tables of contents, inconsistent spacing, and poor EPUB structure can lead to unreadable books, printing problems, and negative reviews. Professional interior book files require proper layout structure, correct gutter calculations, clean paragraph styling, embedded navigation, and formatting designed specifically for KDP’s printing and ebook systems. In this article, we explain what KDP doesn’t clearly tell authors about interior book files, the hidden technical rules behind professional book formatting, and why properly built print and ebook files are essential if you want your book to look professional and compete with traditionally published titles.
