Map in Minecraft: how it works and how to build a map wall

A freshly crafted map is empty; it activates when you use it and from then on draws a top-down view with north at the top. It does not centre on you: the world is split into an invisible grid and the map shows whichever square you activated it in. That is why two maps of the same size never partly overlap. It only records the surface, even when you are underground, and to update it you have to pass through the area again holding it.

A standard map shows 128×128 blocks, one block per pixel. It can be zoomed out four times, up to 2048×2048. In Java each pixel takes the colour of the most common block in its area, so small features vanish on zoomed-out maps; in Bedrock it only reads the topmost block at one specific point.

Maps look great in an item frame, because the frame expands. Four level 2 maps in a 2×2 wall cover the same area as one level 3 map, but with twice the detail. A framed map marks its position with a green dot on its copies, handy as a waypoint. In Java, using a map on a placed banner marks it with the banner's colour and name.

It also works for art: build a 128×128 picture on the ground, centre a map over it and lock it in a cartography table so it never changes. In the Nether, though, a map only shows a red and grey pattern and the pointer spins constantly.
