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

World types[edit]

All editions[edit]

Type Description Image

Default (JE/3DS)
Infinite (BE)
This is the default type of generation. Various landscapes generate utilizing Biomes.

Superflat (JE/CE)
Flat (BE/3DS)
This type of generation creates a world that is completely flat, at an altitude of Y=4, by default. On a classic (default) superflat world, the terrain consists of one layer of bedrock, two layers of dirt and one layer of grass. Mobs spawn normally; slimes are prevalent.

In superflat worlds, villages also generate, and superflat worlds can be further customized through the use of presets, which allows the player to change the layers of the terrain, spawn trees, larger villages, strongholds, etc.

Java and Legacy Console Editions[edit]

Type Description Image

AMPLIFIED (JE)
Amplified Worlds (CE)

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.

In the Legacy Console Edition, this is available for Xbox One and PS4 only, but terrain generates to about Y=128 instead of the world height limit, but foliage may still go above Y=128. It can be selected together with any of the world sizes described in the section below.

Java Edition exclusive[edit]

Type Description Image
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.

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.

Buffet A customisable world type that creates a world of a single biome. It can be generated using the surface, floating islands, and cave options, which result in Overworld, the End and Nether generation, respectively – regardless of whether that biome is normally found in that dimension.
