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

Generates many large mountains that dwarf even the mountains 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. swamplands, 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=0 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)

Caves[until JE 1.18]
Uses generation settings that are similar to those of the Nether in the Overworld. The world generates with a bedrock floor at the Y=0 lower height limit and a bedrock ceiling at Y=127, and the world is generated in between these two like a giant cave complex, much like the Nether. Like other Buffet world types, this world type makes the Overworld only have one selected biome. Villages commonly spawn on top of the bedrock ceiling due to the large surface area available. Caves type world example (using Night Vision to enhance visibility)

Floating Islands[until JE 1.18]
Uses generation settings that are similar to those of the End outer islands in the Overworld. There is no bedrock ceiling or floor to the world, and the entire Overworld is generated in the shape of a series of floating islands, much like the End outer islands. Like other Buffet world types, this world type makes the Overworld only have one selected biome.

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 ⇧ Shift 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.

A JSON-driven customizable world where the the generation of existing dimensions can be changed and new dimensions can be added. World-type-custom.png

Bedrock Edition exclusive[]

Type Description Image
Old[until BE 1.18.0] This world type has a finite area of 256×256 blocks with an invisible barrier surrounding it.

In Pi Edition, which is based on Pocket Edition v0.6.1 alpha, this is the only world type.

Converting from old to infinite world is possible, but incompatible with Minecraft China.

  • The Sky Dimension can be recreated with the Floating Island world type and selecting the Biome as that in Overworld (e.g. forest, plains, mountains, etc.)
    • In fact, the JSON-driven custom world can further reproduce the Sky Dimension on fixed time, minimum internal light, etc.
