From print specs to a downloadable cover concept.
See how RodBooks sizes the wrap from your trim and page count, composites your hero shots as stickers, places badges from the template, and exports a PNG for KDP or further editing.
One cover workflow
Concept at KDP proportions, not a random square.
Print specs drive the canvas. Your title stack, heroes, and badges stay on the template while AI fills the background direction.
01
Set print specs
Choose full wrap or front only, pick a trim preset, enter page count and paper type, and keep bleed on so spine and edges stay in proportion.
02
Upload heroes and previews
Add one to three front hero images required for generation. Optionally upload up to four interior preview pages for the back cover when you want Look Inside style proof.
03
Add title stack and badges
Enter title and continuation text, pick an admin template palette, and attach marketing badges such as year, large print, difficulty, or feature callouts within placement rules.
04
Generate and download PNG
Generate the concept, review dimensions at 300 DPI, download the PNG, then confirm exact wrap size in Amazon’s official KDP cover calculator before upload.
Cover concept studio
Layout direction at real print math.
Cover Designer sizes the canvas from KDP print inputs, composites your product shots without distorting pixels, and downloads a concept you can refine or upload after proofing.
Output modes
Full wrap or front only
Generate a complete wrap concept when you are ready for paperback upload planning, or front-only when you need a faster listing thumbnail direction.
Hero stickers
Your product shots, unedited pixels
Upload one to three hero images. They are composited as stickers so puzzle grids and product photos are not redrawn or stretched by the model.
Marketing badges
Retail-style callouts
Add year, large print, difficulty, feature, and custom badges with placement rules. Only one year badge is allowed per concept.
Back cover
Preview page compositing
When back mode is set to interior previews, uploaded puzzle or solution pages can be placed as immutable stickers so Look Inside style proof stays accurate.
Handoff
PNG download for KDP or editing
Download the concept PNG, polish in Canva or Photoshop if needed, then verify final pixel size with Amazon’s cover calculator before publishing.
Concept before you hire
Hierarchy and proportions in one pass.
Strong covers sell puzzle books when trim math, hero placement, and badge hierarchy are readable at thumbnail size. RodBooks focuses the first draft on those publishing constraints.
- Full-wrap or front-only generation modes
- Trim presets including 6×9 and 8.5×11
- Hero stickers and optional back preview pages
- Admin template palettes and marketing badges
Built for different catalogs
One studio. Different cover jobs.
Use the same print-spec workflow for a first puzzle title, a seasonal gift redesign, or a series template you refine volume after volume.
Puzzle book publishers
Hero grids that stay true
Upload real interior or mockup heroes as stickers so sudoku, word search, and maze pages look like the book buyers will open.
Series builders
Repeatable visual systems
Reuse trim, badge language, and template direction across volumes so the catalog looks related without redesigning spine math from scratch.

Cover Designer vs blank design tools
A pretty square is not a KDP wrap.
Generic AI image tools ignore spine width and bleed. Cover Designer sizes the canvas from trim and page count, then places your title, heroes, and badges on that print geometry.

|---|---|
| Blank Canva or Midjourney square | RodBooks Cover Designer |
| Guess at wrap dimensions | Canvas sized from trim and page count |
| AI redraws product photos | Hero stickers keep uploaded pixels intact |
| No badge placement rules | Marketing badges with retail-style limits |
| Front art only by default | Full wrap or front-only modes |

KDP cover concept guide
How to use Cover Designer without upload surprises.
A practical sequence for locking print specs, preparing heroes, generating a readable concept, and confirming Amazon’s official wrap size before you publish.
1. Lock trim, page count, and binding first
Cover Designer acts as a layout calculator: trim, page count, and paper type set spine width and the full wrap canvas at 300 DPI with bleed. Enter the real interior page count you expect to upload, not a guess. Changing page count later changes spine width. Confirm the final pixel dimensions with Amazon’s official KDP cover calculator before you treat any PNG as upload-final.
2. Prepare hero stickers that match the book
Upload one to three clear front heroes. Puzzle book covers convert when buyers can recognize the interior format in the thumbnail. Because heroes are composited as stickers, use sharp crops and avoid busy backgrounds that fight the title stack. Optionally add up to four back preview pages when you want interior proof on the wrap.
3. Write a title stack that survives thumbnail size
Enter the main title and continuation text the template will place. Keep the promise aligned with the interior: large print, puzzle count, audience, and difficulty should match what the book actually contains. Add marketing badges for year, large print, difficulty, or features, but do not overload the front. Only one year badge is allowed per concept.
4. Generate, then proof readability
Each generation costs 10 AI credits on plans that include credits. Review the concept for contrast, badge crowding, and whether heroes remain recognizable small. AI supplies background direction from the admin template palette; your title, badges, and stickers are placed from the template at the calculated size. Download the PNG when the hierarchy looks solid.
5. Verify wrap size and polish before KDP upload
Treat the download as a high-quality concept at correct proportions, not an unchecked upload. Confirm exact wrap dimensions in Amazon’s cover calculator, proof spine text if present, and refine in Canva or Photoshop when you need micro-adjustments. Bleed vs no-bleed is an interior decision separate from the wrap: puzzle interiors are often no-bleed, while the cover wrap still needs bleed.
Frequently asked questions
Before you generate a cover concept.
Clear answers about wrap sizing, credits, hero uploads, badges, output readiness, and how this differs from a blank design tool.
Is Cover Designer a KDP cover size calculator?
It sizes the wrap canvas from trim, page count, and binding so spine and bleed stay in proportion. Use it for concepts, then confirm the exact wrap in Amazon’s official KDP cover calculator before upload.
Is the output ready to upload to KDP?
It is a high-quality concept at correct proportions. Always verify dimensions with Amazon’s calculator and proof text readability before publishing.
How many credits does each generation use?
10 credits per cover generation on plans that include AI credits.
Can I generate a full wrap or front only?
Yes. Choose full wrap when you need back, spine, and front together, or front only when you want a faster front-cover concept.
Can I use my own hero images?
Yes. Upload one to three front hero shots. They are composited as stickers without pixel edits so your product photos stay intact.
What are marketing badges?
Optional retail-style callouts such as year, large print, difficulty, feature, or custom text. Placement follows template rules, and only one year badge is allowed per concept.
Where do color palettes come from?
Admin-curated Cover Designer reference covers. Each run uses an enabled template palette from those settings.
Which trim sizes can I choose?
Presets include common KDP sizes such as 6×9, 8.5×11, 8×10, 7×10, 5.5×8.5, and 5×8. Always confirm your final wrap against Amazon’s calculator for the trim and page count you will publish.
