Maze generator
Rectangular mazes from tiny to enormous, with exactly one way through. Print the maze with its solution on the next page, or download it as a PNG or SVG.
A 15 × 20 maze: the route from start to finish passes through 54 squares, and there are 29 dead ends.
Making a maze to print
Choose how many squares across and down. Around 10 × 12 suits young children; 25 × 35 keeps adults busy, and up to 80 squares each way are possible for a poster. The page keeps the maze in proportion, so tall mazes fill a portrait page best.
Every maze here is a perfect maze: every square can be reached, and there is exactly one path between any two squares, with no loops to go round in. The three building methods give the same guarantee but feel very different to solve, as described next to each choice. Try the same size with each one and compare.
The round dot and the arrow pointing in mark the start; the square and the arrow pointing out mark the finish (green and red on screen, black on paper). Switch to Solution to see the route drawn in, or leave “Print the solution on a second page” ticked to get an answer sheet. To make a PDF, choose “Save as PDF” in the print window. PNG downloads are sharp enough for worksheets and slides; SVG stays crisp at any size, for cutting machines and design software.
Questions
Which maze is hardest?
For the same size, Kruskal's and Prim's mazes have many more dead ends to explore, while the recursive backtracker's single long route is easier to follow but takes longer to walk. Size matters most of all.
Can I use the mazes in my worksheets?
Yes. The mazes you make are yours to print, copy and share, in class or anywhere else.
How do I get the same maze again?
Keep the maze number, size and building method; together they always make the same maze. The number is printed at the foot of the page.
