Paperback wraps are the core. You can also produce front-cover assets suitable for ebook listings from the same project direction.
Cover Studio
KDP cover generator for full-wrap paperbacks
Generate Amazon KDP paperback covers with spine width from your real page count — AI concepts plus a calculator-aware editor that exports print-ready wrap PDFs.
KDP needs a wrap — not a front-only JPEG
Amazon paperback uploads expect a full-wrap cover PDF: back cover, spine, and front cover in one piece, sized for your trim and page count. A pretty Canva front cover still fails when the spine is wrong or the barcode area collides with artwork. BookWizard’s KDP cover generator is built around that manufacturing reality.
Cover Studio starts from your project’s trim size and estimated or actual page count. Spine width is not a guess — it is calculated for KDP’s paper assumptions so your title and author lines land on the spine instead of wrapping onto the front. That is the difference between a cover tool and a KDP cover generator.
Ebook covers are simpler (front image), but if you plan both formats, generate the wrap for paperback and derive a clean front crop for Kindle. /ebook-vs-paperback-kdp explains the format tradeoffs; this page focuses on the wrap.
AI concepts plus a calculator-aware editor
You can brief Cover Studio for genre, mood, and typography constraints, then generate concept directions. The point is not infinite random images — it is a shortlist that already knows it must live on a wrap template. From there, the editor lets you place title, subtitle, author, and back-cover copy inside safe zones.
Operators who previously juggled a spine spreadsheet, a designer brief, and a last-minute PDF flatten appreciate having page count → spine → layout in one project. When Autobook adds pages, revisit the cover before export so the wrap still matches. Export Studio’s checklist.md reminds you to confirm cover/trim pairing.
Want the wider pipeline? /amazon-kdp-ai-book-generator covers manuscript through listing. Cover is one module — but it is the module Amazon’s previewer judges in a second.

Quality bar: DPI, margins, and barcode space
KDP is picky about resolution and about leaving room for the ISBN barcode on the back cover. Cover Studio’s templates keep critical text away from edges and the barcode zone. You still review the proof — especially if you place dense back-cover bullets or light text on busy art.
If you are choosing trim first, read /amazon-kdp-trim-sizes before locking cover art. A design built for 6×9 does not automatically become a correct 5×8 wrap. Changing trim late forces a cover rebuild; changing it early is free.
Agencies should standardize cover review checkpoints per client (concept approval → wrap proof → final PDF). /use-cases/agency-client-books outlines that production discipline.
Suggested cover workflow inside BookWizard
Run or approximate page count early. Set trim in intake. Generate cover concepts after you trust the page budget. Approve a direction, place copy, export wrap PDF, and only then upload to KDP alongside the interior. Use the Chrome extension and Publish Studio for listing fields in parallel — covers and metadata are separate Amazon steps but one BookWizard project.
Side hustlers shipping many niches can reuse cover briefs with swapped titles — carefully. Amazon hates duplicate or misleading covers across thinly veiled titles. Use Cover Studio speed for legitimate differentiation, not clone farms.
