Amazon's Kindle Direct Publishing (KDP) lets anyone put a book in front of millions of readers — no agent, no publisher, no upfront cost. The catch is that the path from a finished manuscript to a live listing runs through a dozen specific, fiddly steps: trim sizes, bleed, mirrored margins, keywords, categories, file formats. Miss one and your upload bounces back.
This guide walks the entire process end to end, in plain English. It applies no matter what tools you use — though Inkbound is built to handle the technical steps (formatting, covers, valid exports) so you can stay focused on the writing.
Step 1 — Finish a complete manuscript
KDP publishes whatever you give it, so everything starts with a finished draft. Write to "The End" before you worry about formatting or covers — a complete manuscript is what every later step depends on. If you want a tireless first reader along the way, Inkbound's AI writing studio can draft, continue, and pressure-test scenes in your voice while you keep the pen.
Step 2 — Edit and proofread
Amazon doesn't screen for quality, so editing is entirely on you — and it's what separates a book that sells from one that sinks under one-star "needs editing" reviews. Do a structural pass (pacing, stakes, arcs), then a line edit (clarity, rhythm), then a proofread for typos. Beta readers and, ideally, a human editor are worth it; at minimum, read the whole thing aloud.
Step 3 — Format the interior
This is where self-published books most often give themselves away. A print book needs the right trim size (6 × 9 in is the safe default for most fiction and non-fiction), mirrored margins with a gutter that grows with page count, running heads, and chapters that open on a fresh page. Your eBook needs a clean, reflowable file instead. Inkbound's book formatting handles all of this with a live, print-accurate preview — and our deep-dive on how to format a book for KDP covers the specifics.
Step 4 — Design a cover that converts
Your cover is the single biggest driver of clicks on Amazon. An eBook needs a front-cover image; a paperback needs a full wrap — back, spine, and front as one file — with 0.125" bleed at 300 DPI, and a spine width calculated from your exact page count and paper stock. Get the math wrong and KDP rejects the file. Inkbound's cover lab does the geometry for you and includes an AI art director to get you a strong starting design.
Step 5 — Set up your KDP account and metadata
Create a free account at kdp.amazon.com and start a new title. The metadata you enter here is doing SEO work inside Amazon's search, so treat it carefully:
- Title & subtitle — exactly as they appear on your cover.
- Description — your back-cover blurb; light HTML (bold, line breaks) is allowed and helps.
- 7 keywords — phrases real readers search, not single words.
- Up to 3 categories — pick specific, less-crowded ones to rank as a bestseller.
- ISBN — take KDP's free one, or supply your own to be the publisher of record.
Inkbound's publishing workbench helps you draft the description, keywords, and categories, and even generate A+ Content.
Step 6 — Upload, preview, and publish
Upload your interior file and cover, then use KDP's previewer to catch problems before readers do — it flags margins, bleed, and spine issues. This is where valid files matter: Inkbound exports a validated EPUB 3 and a print-ready PDF built to KDP's spec, so the previewer stays green. Fix any flags, set your territories and pricing, and hit publish.
Step 7 — Price, launch, and keep improving
Choose your royalty option (eBooks earn 70% in the common price band; print royalties are list price minus printing cost), set a launch price, and go live — KDP usually makes the book available within 72 hours. After launch, gather reviews, watch which keywords and categories perform, and remember you can update your book, cover, or metadata anytime at no cost. Self-publishing isn't one-and-done; it rewards iteration.
