A book made in ChatGPT lives as a stack of images in a chat window. Turning that into a bound book on a shelf takes two things: pages that meet print specs, and a press to put them on paper. This page covers both: what "print-ready" means in numbers, and the full landscape of ways to get it printed, from do-it-yourself print-on-demand to handing us the whole job.
Haven't made the book yet? Start with our free guide, how to make a picture book in ChatGPT (copy-paste starter prompt included), then come back here. And if a quieter question is holding you back (is it even OK to print AI-generated art?), the answer for your own family is yes: the copyright guide covers why, with sources.
What "print-ready" means
A phone screen forgives almost anything; a printed page forgives nothing. Whatever route you pick below, the press will hold your pages to the same four specs:
- Resolution: 300 DPI at the printed size. For a 9×7-inch landscape page that's about 2784 × 2176 pixels. Chat-default image sizes fall well short: they look crisp on screen and soft on paper, and upscaling can sharpen a near-miss but can't invent detail that was never there.
- Bleed: art runs past every edge. Presses print slightly oversized pages and trim about an eighth of an inch (3 mm) off each side. Backgrounds must overshoot the trim line; art that stops at the edge leaves a thin white rim where the blade landed.
- Safe area: faces and words stay in from the edges. The same trim that removes the bleed can clip anything near it. Keep characters roughly 7–9% in from every edge and text a full 10% in; a clipped letter is far more noticeable than a clipped leaf.
- Page count: about 32 interior pages. Most binderies need roughly 24–32 pages before a proper bound spine works at all. 32 is the classic picture-book length, and it's our minimum too.
One more decision before any printing: trim size, the finished page dimensions. Picture books are usually square (8.5×8.5 in) or landscape (9×7 or 10×8 in). Pick the trim first, because your images' aspect ratio has to match it; a stack of landscape pages can't become a square book without cropping every scene.
Getting the pages out of the chat
Download each page image at full size: the download button on the image itself,
not a screenshot. A screenshot captures the image at your screen's resolution,
which throws away most of the pixels the press needs. Name the files in reading
order (page-01, page-02, …) as you go; sorting 32
near-identical watercolors by memory is worse than it sounds.
Your options for printing it
There are several ways to print a book like this, and the right one depends on how much of the production work you want to do yourself. All of these work; here's what each one asks of you.
Print-on-demand, do-it-yourself (Lulu, Blurb, and similar)
Print-on-demand services will bind a single copy of a full-color book, typically $10–20 to print plus shipping for a 32-page softcover, depending on trim, paper, and cover. The catch is that they take finished files, not images: you assemble an interior PDF at the exact trim size plus bleed, and a separate wraparound cover PDF whose spine width you calculate from the page count and paper stock. Expect an evening in a layout tool and, if you're wise, one proof copy before the version you keep. If you enjoy that kind of production work, this is the cheapest path to a bookstore-grade object.
Photo-book builders (Shutterfly, Mixbook, and similar)
Drag-and-drop editors, no PDF required: the gentlest tooling of any route. If your story text is already painted into the art, full-bleed image pages carry the whole book cleanly. The result reads as a photo album rather than a picture book: thicker photo paper, album-style binding, often a logo page at the back. For some books that's fine; for a book meant to sit beside the ones on your kid's shelf, it shows.
A local print shop
The fastest way to hold a draft; many shops turn a job around in a day or two. Binding options usually run to spiral, staple, or perfect-bound on cardstock rather than a true casebound picture book, and they'll want a finished PDF just like the print-on-demand route. Good for proofing the book before committing to a nicer edition; rarely the keeper copy itself.
Where PrintBound fits
PrintBound is the route where the production work disappears. It's an MCP server, a connector you add to your AI assistant. Once connected, you say "print this as a book" in the same chat where you made it. It pulls every page and illustration from the conversation, sharpens the art to print resolution, lays out the interior with bleed and safe areas, builds the cover spread, and sends the book to a professional print-on-demand press. What arrives is a 9×7 landscape full-color book, softcover $34.99 or hardcover $49.99, all in, US shipping included — printed and shipped within 7–10 business days of payment, with tracking the moment it ships.
Two caveats: we ship to US addresses only at launch, and we're pre-launch: you can't order today. Leave your email and we'll tell you the moment ordering opens. If you'd rather not wait, the do-it-yourself routes above work now, and everything in the specs section applies to them just the same.
Common questions
What resolution do AI-generated images need to print well?
300 DPI at the final printed size. For a 9×7-inch landscape page with bleed, that's about 2784×2176 pixels. Ask for the size explicitly when generating; chat defaults fall short.
How many pages does a printed book need?
Most binderies need roughly 24–32 interior pages before a bound spine works. Plan for about 32, the classic picture-book length and our minimum. If your book came out shorter, a few new spreads are quicker to add than you'd think; the outline step of the guide shows how.
How much does it cost to print a book made in ChatGPT?
Doing it yourself through print-on-demand: typically $10–20 to print a single full-color softcover, plus shipping, depending on trim, paper, and cover, plus your own hours on layout. Through PrintBound: softcover $34.99, hardcover $49.99, all in, US shipping included; the layout hours are the part you're not spending.
My images are too small. Can upscaling fix them?
Partly. Upscaling sharpens an image that's already close to print size, and it's a step we run on every book. What it can't do is invent detail that was never there: a chat-default image blown up to full-page stays soft, and painted lettering suffers first. The reliable fix is regenerating those pages at about 2784×2176 pixels; the style-sheet method in the guide keeps the regenerated pages matching the rest of the book.
