KDP Export
Print presets in all five KDP trim sizes produce single-page PDFs with embedded fonts and gutter margins computed from page count. Kindle export is a reflowable EPUB. Also DOCX, Markdown, and plain text. A readiness check reports what needs attention before you publish.
Cover Studio
Cover Studio has two paths. Create Cover generates new cover concepts from your manuscript identity. Prepare Existing Cover takes artwork you already have and makes it print-ready. The Print Cover Calculator computes exact spine width, wraparound dimensions, and barcode clear zone for both paths.
KDP Keywords
Seven KDP keyword slots, 50 characters each. Generate suggestions from the blueprint, chapter summaries, and promises. Suggestions fill only empty, unlocked slots. Type your own, lock individual keywords, edit freely.
A+ Content
Generate A+ content modules from the manuscript record: a hook, the method or structure, who it is for, what changes for the reader, and a visual module. Each module has editable text, an image prompt, and a Generate image button.

How to Calculate Book Spine Width
Spine width is determined by your page count and paper type. Get it wrong and your wraparound cover does not fit. Here is the formula and how to calculate it for KDP.
