Part of World Border & Difficulty Tools — all tabs in one tool.
World border commands match vanilla Java Edition syntax exactly. Difficulty/game-mode behavior table reflects standard vanilla rules — some servers use plugins/datapacks to modify these.
The default world border size in Java Edition is 59999968 blocks wide, centered at coordinates X: 0, Z: 0. This boundary spans from -29999984 to +29999984 on both horizontal axes, preventing players from traversing beyond the standard playable terrain.
Minecraft Bedrock Edition lacks the /worldborder command and relies on border blocks or invisible barriers at X/Z ±30000000. To restrict players on Bedrock, you must place border_block items in Creative mode with Education features enabled or use custom behavior packs.
Set the center using /worldborder center and define the diameter with /worldborder set . For example, running /worldborder center 100 -200 followed by /worldborder set 500 creates a 500-block square zone centered at those specific coordinates.
Reset the boundary to default vanilla specifications by running /worldborder set 59999968 followed by /worldborder center 0 0. This returns the diameter to its maximum functional limit of roughly 60000000 blocks and recenters the border at origin coordinates.
Players standing beyond the border take suffocation-style damage of 0.2 hearts per second per block distance by default, controlled by /worldborder damage amount. Additionally, block interactions, mob spawning, and standard entity physics are disabled outside the perimeter.
