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

World types[]

All editions[]

Type Description Image

Default (JE)
Infinite (BE)
This is the default type of generation. Various landscapes generate utilizing Biomes. Overworld.jpg

Superflat (JE)
Flat (BE)
This type of generation creates a world that is completely flat, with its lowest layer at Y=0. In Bedrock Edition, and by default in Java Edition, the terrain consists of one layer of bedrock, two layers of dirt and one layer of grass; the surface is therefore at Y=4. Mobs spawn normally; slimes are prevalent.

in Java Edition, superflat worlds generate villages and can be further customized through the use of presets, which allow the player to change terrain layers, spawn trees, and generate larger villages, strongholds, etc.

In Bedrock Edition, structures never generate and the only customization possible is the layer organization, which can only be done with third-party tools.

Java Edition exclusive[]

Type Description Image

AMPLIFIED
Generates many large mountains that dwarf even the mountains biomes seen in default world types and often reach the world height limit. Due to extremely steep cliffs and unforgiving terrain, careless players may have difficulty surviving in this world type. Certain biomes (i.e. oceans and rivers) may see no obvious change in height. Villages still spawn in this world type regardless of how flat the ground is, causing the buildings to generate in bizarre ways. AmplifiedWorldMojang.jpg

Large Biomes
Generates a default world type, but with each geographic feature 4x larger along the X and Z axis, which results in biomes with 16 times as much area. Because of this, villages, desert temples, jungle temples and other generated structures are all more likely to be found. Large Biome.png

Single Biome
Uses the regular generation settings in Overworld: the world generates with a bedrock floor at the Y=-64 lower height limit, and the rest of the terrain is generated on top of it. However, there is only one biome in Overworld, which can be selected by the player at the time of world creation. Single biome example: beach (fully zoomed out map resolution)

Debug Mode
A world type containing all of the block states laid out in a grid at layer y=70 for convenient viewing. It can be accessed by holding down the ALT key while cycling through the world types.

In this world type, there is a floor on y=60 made of barriers and the player cannot place or destroy blocks.
