A Format
The exact word count, trim size, file format, and front/back matter spec for course creators publishing a lead-magnet or companion book on KDP.
Course creators keep treating the companion book like an afterthought. You spend six weeks on the curriculum, then throw a Google Doc export at KDP the night before launch and wonder why the formatting looks broken on a Kindle. The book is doing real work for you: it's the lead magnet that gets someone into your funnel, the credibility object that makes a stranger trust you enough to buy the $500 course, the thing people can hold up and say "I wrote a book." None of that works if the spec is wrong. Wrong trim size gets you margin warnings. Wrong file format gets you a blurry cover thumbnail. No front matter means no way to route readers into your course. This page is the actual production spec, the numbers Quari Press uses when it builds a course creator's book, so you can stop guessing and start shipping.
Course creator books run 15,000 to 35,000 words. That's a 90 to 150 page paperback. You're not writing a textbook, you're writing the thing that proves you know what you're talking about and pushes the reader toward the full course. Padding it to 60,000 words to feel 'legit' just adds friction between the reader and the CTA.
6x9 inches is the standard nonfiction trim on KDP, and it's what readers expect from a business or how-to book. Interior goes black and white unless you have charts or screenshots that need color, in which case budget for KDP's higher color-print cost per page. Keep margins at minimum 0.5 inches with an extra 0.125 inches on the inside gutter for anything over 150 pages.
Title page, copyright page, then a short intro, then table of contents. After that: put your course or offer link on its own page before chapter one, not buried in the back matter where nobody reads it. Readers who make it through your intro are your hottest leads. Give them the link while they're still warm.
End with a clear next-steps page: what to do after finishing the book, a direct link or QR code to the course, and one more reason to click through. A resources or worksheet appendix works well here too, since course creators often have templates or checklists that pair naturally with the book's content.
KDP wants EPUB or a formatted DOCX/PDF for print, exported at 300 DPI for any interior images or diagrams. If you're also selling direct from your own site or via Quari Press, keep a separate EPUB and a print-ready PDF so you're not stuck reformatting later when you want to sell outside Amazon.
