How to make and sell crossword books on Amazon KDP

Low-content publishing is the corner of Amazon KDP where the value is in the format, not the prose: journals, planners, log books and puzzle books. Crosswords sit near the top of the puzzle list, just alongside word search, and they reward a slightly more careful hand. The demand is steady, the audience skews towards adults and seniors who solve every day, and a good book is mostly a matter of a clear niche, a deep clue bank and a clean, readable interior.

This guide walks the whole path, from picking a theme to uploading a print-ready file. You can make your first puzzle for free in a browser, and you'll only pay when you're ready to build a full book.

What makes a crossword book different

A word search book is a grid of hidden words and a shaded answer key. A crossword is a different animal. Each puzzle is a numbered grid plus an Across and Down clue list, and that clue list is the book's body copy. It is real prose, of unpredictable length, and it has to be read.

So the layout, not just the grid, decides whether a book reads as large print. A good tool reserves the space the clues need at a readable size first, then gives the grid the rest. If the clues will not fit, it should tell you, not shrink them past the point where an older solver can read them.

Step 1: pick a niche, not just a theme

"Crossword" is far too broad to rank or sell. A niche is a theme plus an audience: large-print general knowledge for seniors, easy crosswords for beginners, kids' crosswords by topic, themed puzzles for a hobby or a holiday. Pick something specific enough that the book is obviously for one person.

For a feel for how the topics break down, browse our printable themed crosswords. Each theme there is a real puzzle built from a curated clue bank, which is exactly the raw material a book needs.

Step 2: make a puzzle to see the output

Try the free crossword generator→ first. Type a title and a list of answers with their clues, press generate, and you get a printable puzzle and its solution on two pages. It is the same engine our studio uses, so what you see is what a book page will look like, clue list and all.

A single puzzle shows you the format. A book needs dozens, and it needs them not to repeat.

Step 3: build a deep clue bank

A thin clue bank is the single most common reason a generated crossword book disappoints: the same twenty answers reappear on every page, and a regular solver spots it within a week. The fix is to start from a large pool of clued answers, far more than any one puzzle uses, so each grid draws its own subset.

When you are ready, the KDP crossword maker drafts a clue bank with AI, which you review and edit, then generates a whole graded book from it. You get five grades to build a curve, from easy through medium and hard up to extreme and evil, so a book can open gently and get harder. Every puzzle is de-duplicated against the others and numbered correctly, and you unlock a project once and export it as many times as you like.

A note on honesty, because it matters here: the studio drafts the clues, it does not know them to be perfect. Read them. A crossword lives or dies on its clues, and a quick editing pass is the difference between a book that gets five stars and one that gets a correction in the reviews.

Step 4: get the interior specs right

This is where most first books fail review. Every KDP paperback needs the correct margins, a gutter margin that grows with page count, and, if anything runs to the page edge, bleed. For crosswords, large print is not a nice-to-have, it is what most buyers are searching for, and the trim size has to leave room for both a legible grid and a 14pt clue list.

The short version: pick a common trim like 8.5 by 11 inches for large print, keep at least a quarter-inch outer margin (a half inch reads better around a grid), and let the tool size the gutter for your page count. If a grid and its clues will not both fit on one page at a readable size, a facing-page layout, with the grid on one leaf and the clues on the next, keeps everything large without cramming.

Step 5: include a solutions section

A book of unsolvable puzzles gets returned, and a crossword without answers is worse than a word search without them, because a solver cannot simply scan the grid to check. Every puzzle needs a matching solution, collected in a section at the back with the filled grids, numbered to match. Our studio builds that section for you and exports it as a matching PDF alongside the interior.

Step 6: make a cover and set up the listing

The studio exports a print-ready wraparound cover PDF alongside the interior PDF: back, spine and front on one sheet, sized to your page count, with your title set over a solid colour. That built-in cover is deliberately plain, and for this niche a simple, high-contrast title over a themed background is enough, so you do not need a designer. If you would rather build your own, KDP's cover calculator gives you the exact wrap dimensions for your page count.

For the listing itself, write a title and subtitle that name the niche and the format ("Large Print Crosswords for Seniors, 80 Puzzles with Solutions"), fill the seven keyword slots with phrases a buyer would type, and choose two browse categories.

Step 7: understand the maths

KDP pays a royalty after printing costs. For a black-and-white paperback, printing is priced per page, so a large-print crossword book with roomier pages costs a little more to print but reads far better and earns better reviews. Price in the range buyers expect for the niche, usually a few dollars, and let the catalogue, not any single title, do the earning over time.

A realistic first project

Make one free puzzle to see the output. Pick a specific niche. Build a deep clue bank and generate around 70 to 80 graded puzzles with solutions in the studio, read the clues and fix the weak ones, export the interior at a large-print trim, make a simple cover, and upload. Then do it again for the next niche. The compounding comes from a shelf of focused books, each easy to find because it is clearly for one reader.
