Minecraft wiki entry for World_boundary, associated text: In the Xbox 360 Edition, PlayStation 3 Edition, PlayStation Vita Edition, and Wii U Edition, the Overworld is limited to 864×864 blocks. Additionally, in the Xbox One Edition, PlayStation 4 Edition and Nintendo Switch Edition, the player is able to further select the size of their worlds, from Small (1024×1024), Medium (3072×3072), and Large (5120×5120, except Nintendo Switch Edition). The edges of these worlds are surrounded by an invisible barrier with an endless sea of water beyond it. Before being patched out over time, there were often several exploits that could be used to glitch past the border, such as using boats, or using hundreds of TNT Minecarts to blow the player above the world height cieling.
