Altitude is a measurement of vertical distance, or distance along the Y-axis.

Definition[edit]

Altitude is defined as "the height of anything above a given planetary reference plane, especially above sea level on earth."[1]

In Minecraft, altitude is often expressed as the bottom face of a block layer, where the lowest block that can be placed is at layer 0 and has a Y-coordinate of 0 (in Java Edition 1.17[upcoming] and Bedrock Edition 1.17.0[upcoming], this Y-coordinate is −64). For instance, sea level is at layer 62, while clouds appear at layer 127 (in Java Edition 1.17‌[upcoming] and Bedrock Edition 1.17.0‌[upcoming], clouds appear at layer 191).

This is not to be confused with altitude when otherwise expressed as the top face of a block layer, where the lowest block that can be placed is at layer 1 and has a Y-coordinate of 1. For example, sea level is at layer 63, while clouds appear at layer 128. This is akin to calling the ground level storey the "first floor" (top face of a block layer), rather than the "ground floor" (bottom face of a block layer). The player can press F3 to see the Y-coordinate of the top face of a block they are on top of.

Altitude expressed as the bottom face of a block layer is most useful for identifying the position of blocks, such as when using /fill to replace block(s). Expressing altitude as the top face of a block layer is more useful for identifying the position of entities, such as when using /tp to teleport or /summon to spawn an entity/entities. For instance, the topmost block of water in an ocean biome has a Y-coordinate of 62; in a frozen ocean biome, ice replaces water at sea level, and the lowest height where terrestrial mobs will spawn is at layer 63.

Features and effects by height[edit]

Y-coordinate Feature or effect
21024[note 1] Largest height Minecraft can distinguish from infinity, Java's Double.MAX_VALUE.[2]
36,028,797,018,963,968 Above this height, players cannot move vertically except using NBT editors.
4,503,599,627,370,496 Maximum height reachable by flying, the point where the Double datatype stops growing in steps of 0.5.
2,147,483,648 In Bedrock Edition, the game crashes beyond this point.
30,000,000 In Java Edition, players above this height are kicked with an "invalid move player packet received" error, but this can be fixed through external programs. This is the maximum height the player can teleport to.[3]
In Bedrock Edition, this is the maximum height the player can teleport to.
2,032 Top face of the highest block that can be placed in a Custom world generated with the maximum build height.
511 Maximum height the player can travel to in Legacy Console Edition.
320 Top face of the highest block that can be placed in Java Edition 1.17[upcoming] and Bedrock Edition 1.17.0[upcoming].
256 Top face of the highest block that can be placed in Java Edition and Bedrock Edition‌[until JE 1.17 & BE 1.17.0].
Bottom face of the highest block that can be placed in Legacy Console Edition.
255 Highest layer where dirt and gravel can generate, replacing stone, granite, diorite and andesite.[4]
191–195 Range of cloud layers in Java Edition 1.17‌[upcoming] and Bedrock Edition 1.17.0‌[upcoming].
127–135 Range of cloud layers.
127 Full bedrock layer in the Nether.
Highest layer where coal ore can generate, replacing stone, granite, diorite and andesite.[4]
Highest layer where nether quartz ore, nether gold ore and ancient debris can generate, replacing netherrack, basalt, and blackstone.[4]
In Bedrock Edition, this is the bottom face of the highest block that can be placed in the Nether.
123–126 Range of partial bedrock layers in the Nether.
79 Highest layer where gold ore within badlands biomes, granite, diorite and andesite can generate, replacing stone, granite, diorite and andesite.[4]
50–70 Range of layers where slimes are able to spawn in swamps.
63 Highest layer where infested stone within mountains biomes and iron ore can generate, replacing stone, granite, diorite and andesite.[4]
62 Sea level.
Phantoms only spawn if players are above this level.
40 Highest layer where slimes are able to spawn within "slime chunks" outside of swamps.
36 Highest layer where gravel and blackstone can generate, replacing netherrack, basalt, and blackstone.[4]
31 Highest layer where gold ore outside of badlands biomes and lapis lazuli ore can generate, replacing stone, granite, diorite and andesite.[4]
4–31 Range of layers where emerald ore within mountains biomes can generate, replacing stone.[4]
15 Highest layer where redstone ore and diamond ore can generate, replacing stone, granite, diorite and andesite.[4]
11 Lava replaces air below this layer.
1–4 Partial layers of bedrock in the Overworld and the Nether.
0 Full bedrock layer in the Overworld and the Nether.
Top face of the Void; bottom face of the lowest block that can be placed.
Liquids do not flow below this layer.
In Bedrock Edition, entities and players not in Creative mode begin to take damage below this layer.
−7–0 Partial layers of deepslate in the Overworld in Java Edition 1.17‌[upcoming] and Bedrock Edition 1.17.0‌[upcoming].
−8 Deepslate replaces stone below this layer in Java Edition 1.17‌[upcoming] and Bedrock Edition 1.17.0‌[upcoming].
−40 In Bedrock Edition, an invisible border prevents players from falling. This can be bypassed by using /tp, unless the player teleports within the Stripe Lands.
−64 In Java Edition, players below this height take void damage (4♥♥ per 12 second), even in Creative mode‌[until JE 1.17]. This damage cannot be prevented or mitigated, but commands can provide enough regeneration to survive it. Non-player entities falling below this height despawn instantly.
Bottom face of the lowest block that can be placed in Java Edition 1.17‌[upcoming] and Bedrock Edition 1.17.0‌[upcoming].
−104 An invisible border prevents players from falling in Bedrock Edition 1.17.0‌[upcoming].
−128 Players below this height take void damage in Java Edition 1.17‌[upcoming].
−2,032 Bottom face of the lowest block that can be generated in a Custom world with the maximum build height‌[upcoming].
−65,536 Upper limit of the bottom face of the lowest temporary (isn't saved) block that can be placed in a Custom world (the lower it is, the slower the game runs). However, it can only be accessed through external programs.
−16,777,216 In Bedrock Edition, the player cannot fly below this layer. Every second block is invalid; because players are 2 blocks tall, it is impossible to enter. If bypassed via commands, the player experiences extreme jitter and camera movement.
−30,000,000 In Java Edition, the player is kicked from the world below. This is the minimum height the player can teleport to.[3]
  1. 21024 is approximately equal to 1.8 × 10308, or 180 uncentillion.

Natural resources and altitude[edit]

Features in the landscape of the Overworld are found at different altitudes, as shown in the graph below.

Resource distribution by altitude (Minecraft 1.16.4, overworld).svg

Note that these charts utilize the logarithmic scale, which means a slight difference in the Y-coordinate represents a large change in the relative frequency of a block type.

Some observations:

  • Looking at water, the amount at layer 62 (sea level) is obvious. Moving down, the amount quickly decreases at layers 56 and 48, the usual depth of river and ocean biomes respectively.
    • There are corresponding peaks in the amount of clay beneath them.
  • Between layers 33 and 12, most water is falling down sub-ocean ravines, spreading out on the lava-filled bottom at layer 10 and producing most of the naturally-occurring obsidian.
  • Ores and gravel (not shown) usually occur as a fixed percentage of the amount of stone (also not shown), tapering off at the ends of their allowed generation range.
    • This is why coal and iron follow parallel tracks between layers 5 and 60.
    • The one exception is lapis lazuli ore, which has a linear progression up to a peak at Y = 15.

History[edit]

A screenshot shown by Notch of an experimental 512-block-high world.
Java Edition Classic
?The altitude of the map was 64 blocks total. Players could build 32 blocks up or down from sea level.
Java Edition Infdev
Minecraft Infdev20100227-1Height limit was 128. However, during the development of this version, it was raised to 256.
Java Edition Beta
1.6Test Build 3Solid blocks can no longer be placed on layer 127. However, beds, signs, torches and other non-solid blocks can be placed on layer 127.
Entities are no longer invisible when above the build limit; instead, they turn black.
July 19, 2011Notch, on his Twitter feed before the Adventure Update, posted a picture showing his experimentation with height limits and terrain generation up to 512, featuring a mountain much higher than normal mountains.
1.8Pre-releaseAdded altitude-based void fog.
Previously, the sea level was at layer 63. Now, it is at layer 62. Worlds created before this update generate one-block-high "waterfalls" at the boundary between previously-generated terrain and new, post-Beta 1.8 terrain.
Java Edition
1.2.112w07aThe height limit was doubled from 127 to 255, although structures did not yet generate above this layer.
The change in height was introduced along with the switch from the Region file format to the new Anvil file format.
1.7.213w36aAmplified world type added (attempts to use the full 255 height).
1.8.2pre7Raised the build limit from 255 to 256 and prevented non-solid blocks from being placed one block higher.
1.1116w32aThe height limit message now appears on top of the hotbar, the place where the message "Press LSHIFT to dismount" also appears when riding a mob.
1.1418w43aLight is no longer observable above 2,048 blocks.[5]
Upcoming Java Edition
1.1720w49aThe height limit can now be increased in the custom worlds settings. Because of errors, it can be increased only up to 512 and down to −256 below bedrock.
?Fixed those above errors.
21w06aThe world has been extended 64 blocks in both (vertical) directions, making it possible to build from layer −64 to layer 319 in the Overworld. This effectively increases the world to 383 buildable layers.
21w15aThe world height changes have been reverted.
Pocket Edition Alpha
v0.1.0The altitude of the map was 127 blocks total. Players could build 64 blocks up or down from sea level.
v0.9.0build 1Previously, the sea level was at layer 63. Now, it is at layer 62. Worlds created before this update generate one-block-high "waterfalls" at the boundary between previously-generated terrain and new, post-0.9.0 terrain.
Pocket Edition
1.0.0alpha 0.17.0.1The height limit was doubled from 127 to 255, with the exception of the Nether and Old world types. However, terrain (excluding structures) generates only up to the old height limit.
Bedrock Edition
1.16.220beta 1.16.220.50Increased height limits from 255 to 319 blocks.

Trivia[edit]

  • The highest possible altitude the player can legitimately climb to is Y = 256‌[until JE 1.17], or Y = 320‌[upcoming: JE 1.17], although explosions, elytra launchers, piston slime block bounces, and Riptide tridents can all propel the player far beyond this limit.
  • In Java Edition, mushrooms can appear on the Nether's bedrock ceiling.[6]
  • Block generation and player construction below and above the build limits can be achieved only through modifying the dimension properties‌[upcoming: JE 1.17], or mods, such as the Cubic Chunks mod.
  • The reasoning behind Custom worlds having height limits of ±2032 rather than ±2048 (a binary number notated as 211) is because the lighting system still applies 16 blocks above and below the world, but the Y-coordinates of blocks (which are also used in the lighting calculation) are stored internally using only 12 bits. Therefore, having limits of ±2048 would prevent the lighting system from functioning correctly.[7][8]
