World type

World type is an option to change how worlds generate in Minecraft.

Java Edition

Main articles: World preset and Custom world preset

When creating a new world, in the "More world options..." screen, players can choose which world preset to use, or not use world preset. World presets are used to determine the dimensions the world has, which can be controlled by data packs.

Bedrock and Education Editions

Type	Description	Image
Infinite	This is the default world generation type. It features the generation of various landscapes, making use of Biomes to separate the world into different environments.
Flat	This world generation type creates a world whose overworld is completely flat, with its lowest layer at Y=-64. The terrain consists of one layer of bedrock, two layers of dirt and one layer of grass; the surface is therefore at Y=-60. Structures are not generated in flat worlds. Mobs spawn normally; though slimes are more prevalent due to the height of the world being less than Y=40.
Old	This world generation type has a finite area of 256×256 blocks with an invisible bedrock barrier surrounding it. Converting from old to infinite world is possible.
