Free Maze Generator: Printable Mazes, Free for Commercial Use

The maze maker above draws a new maze every time you press New maze: pick Easy, Medium or Hard, or choose Custom and set any width and height from 5 to 50 cells. Show answer draws the solution path, Print sends just the maze to your printer (or to a PDF from the print dialog), and PNG saves a sharp image. No sign-up, no watermark, no limit. Use it as a quick maze creator for a single worksheet, or to test sizes before you plan a whole book.

Can you sell what you make? Yes. Mazes generated here are yours to use, including in a book or printable you sell, with no credit line required. That is not true of every free maze generator, so the comparison below shows what each popular one says about commercial use on its own site.

Free Maze Generators for Commercial Use, Compared

"Free to make" and "free to sell" are different promises. These are the terms each site states on its own pages, read on 13 October 2026. Terms change, so read the licence on the site again before you publish.

Two things stand out. First, mazegenerator.net charges for commercial use, and its yearly licence works like a subscription: when it lapses you keep the mazes you downloaded during it but cannot download new ones for commercial use. Second, shapes are where the licences differ most: freemazegenerator.org offers circular mazes under the same free commercial rights, while mazegenerator.net's circular, triangular and hexagonal mazes need its paid licence before you sell them, and twolimeprints.com's heart, star and letter shapes need a membership. For rectangular grids bigger than 50 cells, jigsawmake.com and puzzlegenio.com go up to 200 × 200 and state that their output can be sold.

Five Checks Before You Sell Mazes From Any Generator

One more point applies to every generator: a computer-generated maze is not exclusive. Anyone can make mazes with the same tool, so the value of a maze book is in its theme, cover, difficulty curve and layout, not in owning the grid.

Maze Sizes and Difficulty

Grid size is what drives difficulty: more cells means more junctions, more dead ends and a longer route. The averages below come from running this generator 1,000 times at each size on 13 October 2026, rounded because every batch differs slightly.

The averages hide a wide spread: hard mazes ranged from roughly 30 to 340 cells of solution across those runs. Press New maze until one looks right for the page you are making. For a preschool book stay on Easy all the way through; for adult brain-training books, 30 × 30 and up is where a maze page holds its own beside sudoku and word search.

How This Maze Generator Builds Every Maze

Each maze is carved by a recursive-backtracker algorithm, the standard method for a "perfect" maze: every cell can be reached and there is exactly one path between any two cells, so the solution is unique. Nothing is assembled from templates; every maze comes from its own random seed.

The entrance and exit move on each generation, on opposite edges, so consecutive pages in a book do not look like copies. The answer path is found by a breadth-first search between the two openings, which is why the solution line never doubles back.

Printing Mazes That Stay Readable

Print sends only the maze to the printer and shrinks a large grid to fit one sheet. The on-screen maze is drawn at two to three times screen resolution so lines stay crisp on paper, and PNG saves at three times. Two settings matter more than anything else:

• Paper size. US Letter (8.5 × 11 in) and A4 (8.27 × 11.69 in) are close but not identical. Pick the one in your printer before printing a batch for a class.
• Cell size on paper. On a full Letter-width page a 50 × 50 maze leaves cells of roughly 4 mm, which suits adults with a fine pen. Keep children's mazes at Easy or Medium so the paths stay wide.

For an answer key, print once, press Show answer and print again. In a classroom set, staple the answer pages to the back.

From One Maze to a KDP Maze Book

The free maker is built for one maze at a time. For a paperback you need dozens at a fixed trim size with solutions, which leaves two routes:

Either way, set margins from KDP's own rules: for an interior of 24 to 150 pages the inside (gutter) margin must be at least 0.375 in, and the outside margins at least 0.25 in without bleed. The KDP interior templates guide has every trim size.

What a maze book earns per copy

KDP pays a royalty rate on the list price minus the printing cost. On Amazon.com the rate is 50% at a list price of $9.98 or less and 60% at $9.99 or more, and an 8.5 × 11 black-ink book on white or cream paper with 24 to 110 pages costs a flat $2.84 to print (KDP's printing cost and royalty pages, read 13 October 2026). So a 100-page 8.5 × 11 maze book earns:

Two dollars more on the cover nearly triples what each copy pays, which makes $9.99 the first price to test. Check your own numbers in the KDP royalty calculator and the printing cost calculator, which carry the same rate tables.

Maze Book Themes Worth Considering

Grid size sets the difficulty; the theme and cover sell the book. These angles come up again and again on maze books:

Check demand yourself before committing to a theme: search "[theme] maze book" on Amazon and look at how many results come back and how the leaders rank. For seasonal themes, research 60 to 90 days before the holiday. The puzzle book publishing guide walks through the upload.
