The forest and a mountain range as seen in the Overworld.

The Overworld is the dimension in which all players begin their Minecraft journey.


The Overworld is the only dimension created when the player creates a new world. The other dimensions—the Nether and The End—aren't created until a player enters the corresponding portal.


A new world in Minecraft is generated through the use of a seed, which is an integer used as a starting point for the world generation formula. The player can specify a seed or allow the game to generate one randomly. If given a non-integer input (such as the word "Glacier"), the game converts it into a corresponding integer (such as 1772835215).

A given seed generates almost exactly the same world every time, provided the same edition, game version, and world type are used. Although the exact spawn point varies, the coordinates of all-terrain features are the same. Seeds in Bedrock Edition, Education Edition, and New Nintendo 3DS Edition also generate identical worlds for the same version and world type, but these are completely different from the worlds generated by those seeds in other editions.


The Overworld is an incredibly complex environment with a wide variety of features.

The Overworld is divided into biomes of various types. A biome's type determines the basic characteristics of the terrain within it, and almost all of them have several variations that alter these characteristics to create more realistic terrain. The biome type also influences the biome's size, determines which mobs can spawn within it, and affects how environmental behaviors such as weather are expressed within it.

Natural structures[edit]

The Overworld is composed of a large number of terrain patterns, called structures, whose arrangement varies widely from one seed to another. The exact structures are unique to each world, while the types of structures that can be generated at a given place are determined by the biome type. Structures are meant to represent real-world equivalents such as mountains, caves, and lakes. "Impossible" (in the real world) formations, such as floating islands, can also be found throughout the Overworld.

Along with terrain features, natural structures include naturally-generated buildings, such as villages, dungeons, and mineshafts.

Day-night cycle[edit]

The Overworld is the only dimension with a day-night cycle and the only one where the environment reflects the passage of time. In contrast to time zones in the real world, Overworld time is universal; it is always the same time for every player in the dimension regardless of how far apart they might be, even in an "infinite" world.

During the daytime, the sun acts as a powerful light source, with a light level of 15, the maximum. Sunlight is strong enough to grow plants and affect the way mobs spawn, among other interesting effects. During the nighttime, the moon is the only natural light source. However, moonlight is comparatively dim; the light level falls to a minimum of 4, allowing hostile mobs to spawn. Other than during thunderstorms, nighttime is the only time players may sleep in a bed.

The day-night cycle can effectively be measured using a clock, which allows players to determine the approximate Minecraft time anywhere in the Overworld. Time can also be sped up with the use of the /time command.

The sun rises in the east and sets in the west, just as it does in the real world. Observing its motion is a simple method of telling direction without a compass.


The Overworld is home to a wide variety of mobs. Mobs vary greatly in behavior and the level of danger they present to the player. Different mobs spawn at different times and places depending on the light level and the biome, among other factors. On occasion, a mob can move between the Overworld and another dimension, such as the Nether, by using a portal, but this is uncommon. Boss mobs like the ender dragon and the wither cannot enter portals.

As with all other dimensions in the game, the Overworld can generate infinitely. However, there are some limitations, as detailed below. Like the other dimensions, it is divided into 16×256×16 block sections called chunks.

The Overworld encompasses a three-dimensional volume that extends vertically from the build limit (y=256) down to the Void (y=0), and horizontally for a virtually infinite distance in each direction. This volume is filled (virtually speaking) with air, terrain, and structures. Technically, the terrain is formed by generating multiple noise maps to produce differing elevations, general land shapes, and complex mountain and cave systems.

While the world is virtually infinite, the number of blocks a player may physically reach is limited with where the limits are depending on the edition of the game and the world type being played.

In Java Edition, the map contains a world border located by default at X/Z coordinates ±29,999,984. The world border is an animated wall of blue stripes. Standing near the border results in a red vignette appearing around the screen. Most entities are unable to pass the border, except by teleporting. Players who breach the border receive constant damage unless they are in creative or spectator mode. The player can teleport past the world border and continue as far as X/Z ±29,999,999, where there is an invisible wall. However, the player can travel a few chunks further by riding horses, pigs, and minecarts through it.[verify] Once the player passes X/Z ±30,000,000, "fake chunks" generate in which the blocks have no collision boxes.

In the Bedrock Edition, Old-type worlds are limited to 256 blocks each in the X and Z directions. The edge of the world is barricaded with an invisible barrier. Infinite-type worlds have no fixed horizontal limits, but either generation stops or normal game behavior begins to break down at extreme distances; the exact details depend on the platform. However, experiments suggest that players can generally reach at least X/Z ±12,550,000 before such problems occur.

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.

Terrain features[edit]

The Overworld contains numerous terrain features, at a wide variety of scales.

"Naturally generated" includes blocks that are created through the world seed.

Naturally created means a combination of events that cause a new block to be placed by natural causes, not the player. Some of these blocks may also be created as part of world generation.

In Java Edition, information on the Overworld is stored in the region folder of the .minecraft/saves/worldname directory, with "worldname" being the name of your world.

Deleting the region folder resets the Overworld so that all player-made changes and buildings in that dimension are undone.

Issues relating to "Overworld" are maintained on the bug tracker. Report issues there.



  • The maximum number of blocks that can be generated in the Overworld is approximately 921.6 quadrillion (9.216×1017) blocks, assuming a distance of 30,000,000 blocks in either direction.
    • The total area is about 8 times the surface of the Earth, or approximately the surface area of the planet Neptune.
    • This means that storing a filled world, with no entities or block entities, would require 3.6864 quintillion (3.6864×1018) bits (409 petabytes) for the block data alone, based on the fact that each standard block is assigned 4 bits of information.
    • By manually modifying the game, it is possible to generate the world up to 2,147,483,647 blocks (the 32-bit integer limit) in either direction.
  • A 1:1 (1 block = 1 meter) scale map of the Earth, built-in Minecraft, would be 510.9 trillion (5.109×1014) blocks in size.
    • Assuming the map is one block deep and uses 1 byte per block, its size would be approximately 475,800 GB (464.7 TB).
    • A Moon-sized map would be made of 37.95 trillion (3.795×1013) blocks. Its data size would be 35,340 GB (34.52 TB).
