Map calculator
Find exactly which area a map will show at each zoom level, so map walls line up perfectly.
- Map covers X
- Map covers Z
- Map centre
- Size
How to use it
Enter the coordinates where you'll make or first open the map, and pick a zoom level. The calculator shows the exact area the map covers, its centre, and where the next maps over begin, which is what you need to plan a map wall.
Maps snap to a grid
A map isn't centred on you. The world is divided into an invisible grid of squares, and a new map shows whichever square you're standing in. Every map made anywhere in that square shows the same area.
| Zoom level | Area covered | Blocks per pixel |
|---|---|---|
| 0 | 128 × 128 | 1 |
| 1 | 256 × 256 | 2 × 2 |
| 2 | 512 × 512 | 4 × 4 |
| 3 | 1,024 × 1,024 | 8 × 8 |
| 4 | 2,048 × 2,048 | 16 × 16 |
At every zoom level, the grid lines fall at −64 plus a whole number of map widths. A zoom 0 map made at X 0, Z 0 covers −64 to 63; a zoom 3 map made there covers −64 to 959.
Building a map wall
- Decide the zoom level, then use the calculator to find the first map's area.
- Make each next map by standing inside the next grid square. The calculator tells you where the next square to the east and south begins.
- Place the maps in item frames in the same layout as the grid. Because every map snaps to the grid, the edges line up with no gaps or overlaps.
Zooming out
Zoom a map out with 1 paper on a cartography table, or by surrounding it with 8 paper on a crafting table. A zoomed-out map keeps the same grid, so it covers the bigger square that contains the original.
