How to make a maze book for Amazon KDP

1. Pick a reader and a theme

Every good maze book answers one question on its cover: who is it for? "Mazes" is a shelf with thousands of books. "Dinosaur mazes for ages 4 to 6" or "Large print mazes for adults" is a book a parent or a gift buyer can choose in a second.

• Age decides almost everything: the path width, how many turns, how big START and FINISH are, even the font. Our maze difficulty by age guide lists what fits each age.
• A theme makes it giftable: dinosaurs, space, ocean animals, unicorns, Halloween, Christmas. Seasonal books sell in a short window, so publish them a couple of months early.
• Read the 1 to 3 star reviews of the best-selling maze books in your niche. Readers tell you exactly what went wrong: "too easy for my 8 year old", "lines too thin", "no answers in the back", "the same maze twice". Each complaint is a feature for your book.

2. Choose the trim size

The trim size is the size of the finished book. For maze books, three sizes cover most needs:

• 8.5 × 11 in: the classic activity book. Big pages, big mazes, easy for small hands and for photocopying.
• 8 × 10 in or 8.5 × 8.5 in: a little smaller and very common for children's activity books.
• 6 × 9 in: a travel or pocket puzzle book, mostly for older kids and adults.

All of KDP's paperback sizes, with their page limits, are in our KDP size, margins and bleed cheat sheet.

3. Plan the pages and the difficulty

KDP paperbacks need at least 24 pages (72 for standard color ink). Most maze books land between 50 and 120 pages, counting the answer keys.

• Ramp the difficulty. Open with a few easy wins, then climb. A book "for ages 6 to 8" that starts with the hardest maze loses its reader on page 1.
• One side or both? One maze per sheet (a blank or a light pattern on the back) stops markers from showing through. Mazes on both sides use half the paper and keep the price down. Pencil books can print on both sides; marker books are better on one.
• Give every maze a number. The answer keys at the back need it, and readers like counting their progress.

4. Make the mazes

Whatever tool you use, check every maze for four things before it goes in the book:

1. It has a way through. Solve it, or let your tool solve it, and look at the route.
2. The paths print wide enough. On our free pages we keep every path at least 2.5 mm wide and every wall at least 0.8 pt thick, and much wider for little kids. Thin hairlines vanish on a home printer and on KDP's paper.
3. START and FINISH are easy to find.
4. No two mazes are the same. Readers notice, and KDP's content guidelines frown on books that repeat their content.

In Zigzaggle Studio each maze is generated, solved and checked as you make it: the Review chip flags anything that would print badly, and Solution draws the route. Shape mazes, word and letter mazes, picture mazes and many other maze types sit side by side, so one book can mix a few kinds without looking patched together.

5. Add the answer keys

Put the answers at the back, each labeled with its maze number. For kids, one answer per page is easiest to read. For adult books, several small answers per page keep the book from doubling in length. Keep the answer route a strong color or a thick gray line, so it still shows in black ink.

6. Export the interior PDF

The interior is one PDF with every page at the trim size, or at the trim size plus bleed when art runs to the edge. KDP's rules in short:

• Bleed only if something touches the edge of the page: add 0.125 in (3.2 mm) to the top, bottom and outside edge.
• Margins: at least 0.25 in on the outside edges (0.375 in with bleed), and an inside margin that grows with the page count, 0.375 in up to 150 pages.
• Images at 300 DPI or more, and fonts embedded in the PDF.

In the Studio, Download › More export options › Book interior sets the trim size and the bleed for KDP, puts the answer keys at the back and checks the page count before you download the print-ready PDF.

7. Make the cover

A paperback cover is one wide PDF: back cover, spine and front cover side by side, with 0.125 in of bleed all around. The spine width depends on the page count and the paper: for black ink on white paper it is the page count × 0.002252 in. KDP only prints spine text on books with at least 79 pages, and leaves a box on the back cover for the barcode.

The Studio's Cover Studio draws those guides for you (bleed, spine, safe areas and the barcode box), counts your pages, widens the spine when you change the paper and saves the whole wrap at KDP's size.

8. Upload and order a proof

• ISBN: KDP counts puzzle books as activity books, not low-content books (KDP: low-content books), so a maze paperback needs an ISBN. KDP can assign a free one, or you can use your own (KDP: ISBNs).
• AI content: if your book uses AI-generated images (an AI picture maze, for example), KDP asks you to say so when you publish (KDP content guidelines). Mazes drawn by an ordinary maze generator are not AI-generated images.
• Title, subtitle and keywords should say who the book is for: "Dinosaur Mazes for Kids Ages 4-6: 60 Fun Puzzles with Solutions" tells shoppers and Amazon search the same thing.
• Order a proof copy before you hit publish. Check that the thinnest walls still print, the answer route shows, and nothing hides in the inside margin.

Why maze books get bad reviews (and how to avoid it)

• "Too easy" or "too hard": the age on the cover and the mazes inside don't match. Test a few pages on a real child of that age.
• "The lines are so thin I can't see them": walls drawn at screen thickness. Keep walls at least 0.8 pt and check a printed proof.
• "No answers": always include them, labeled by maze number.
• "Same maze over and over": every page needs its own maze, ideally its own picture too.
• "Where do I start?": mark START and FINISH clearly, and keep them on the outer edge.
