Altitude is a measurement of vertical distance, or distance along the Y-axis.
Altitude is defined as "the height of anything above a given planetary reference plane, especially above sea level on earth."
In Minecraft, altitude is commonly expressed as the number of block layers above the bottom of the game environment, which is layer zero (0). For instance, sea level is recognized as block layer 62, and clouds appear at layer 127.
Altitude may also be expressed as the bottom face of the block layer, the bottom most of which is at Y-coordinate 0, or Y=0. Sea level would appear at Y=63, and cloud level would appear at Y=128. The player can press F3 to see the Y-coordinate of the top face of the block on which they are standing.
Features and effects by height
- Note: This list is projected from the highest to the lowest Y- level.
- 21024 ≈ 1.7976931348623 × 10308
- Largest height Minecraft can distinguish from infinity, Java's
- 255 = 36,028,797,018,963,968
- Above this height, players cannot move vertically except using NBT editors.
- 252 = 4,503,599,627,370,496
- Maximum height reachable by flying, the point where the
Doubledatatype stops growing in steps of 0.5.
- 231 = 2,147,483,648
- The game crashes beyond this point in Bedrock Edition.
- The player is kicked from the world above this height.
- The maximum height of teleportation.
- Top face of the highest block that can be placed.
- Upper limit of Coal Ore generation. Build limit in the Nether for Bedrock Edition
- Full bedrock layer in the Nether.
- Partial bedrock layers in the Nether.
- Upper limit of gold ore generation in badlands and variants.
- Upper limit of slime spawn in swamps.
- Upper limit of iron ore generation.
- Sea level. Players must be above this level for phantoms to spawn.
- Lower limit of slime spawn in swamps outside "slime chunks".
- Upper limit of slime spawn in non-swamp biomes in "slime chunks".
- Upper limit of lapis lazuli ore, emerald ore and (in non-badlands biomes) gold ore generation.
- Upper limit of redstone ore and diamond ore generation.
- Partial bedrock layers in the Overworld.
- Partial bedrock layers in the Nether.
- Full bedrock layer in the Overworld and the Nether. Top of the Void; bottom face of the lowest block that can be placed. Liquids stop flowing when they reach this point. Also, entities in Bedrock Edition take damage after this point.
- An invisible border appears here in Bedrock Edition, which can be bypassed by using
- Players below this height take void damage (4 per 1⁄2 second) in Java Edition, even if in Creative mode. 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.
- Players below this height are kicked with an "invalid move player packet received" error. This can be fixed through external programs.
Limits in Bedrock Edition
The top of the game environment is layer 255, and the top face of the highest block that can be placed is at Y=256.
In Bedrock Edition, the player dies instantly if they fall below Y=-2, unless in Creative mode. In creative mode, the player can fall only into Y=-40,but can use
/tp to lower. The height limit for building blocks is Y=256.
Natural resources and altitude
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.
- 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 layers 13-14.
See the following table for a textual description of resources by altitude and tools needed to gather them.
|Landscape feature||Complete layer range[note 1]||Most common layers[note 2]||Tool needed to obtain|
|Coal ore||1-119||5-56||Wooden pickaxe or better|
|Gravel||1-126||5-56||Not required but faster with any shovel|
|1-126||5-80||Not required but faster with any shovel
(Grass blocks, Podzol and Mycelium drop dirt when broken unless mined with a Silk Touch enchanted shovel)
|Sand||2-112||43-63||Not required but faster with any shovel|
|Iron ore||1-63||2-58||Stone pickaxe or better|
|Gold ore||1-31, 1-100[note 3]||4-28||Iron pickaxe or better|
|Lapis lazuli ore||1-30||11-17||Stone pickaxe or better|
|Emerald ore||4-31||5-29||Iron pickaxe or better|
|Redstone ore[note 4]|
|Bedrock||0-4||0-2||Only breakable in Creative mode|
- The range in which the block can be found in the map used for the graph.
- Layers in which the resources tend to be most numerous.
- In badlands
- Redstone has the same layer and line-size statistics as diamond, but is generated 8 times per chunk as opposed to 1.
Other naturally occurring features appear at different altitudes, but all of these features are random and appear only in conjunction with another block and the proper environment.

|?||The altitude of the map was 64 blocks total. Players could build 32 blocks up or down from sea level.|
|Java Edition Infdev|
|Minecraft Infdev||20100227||Height limit now 128. However, during the development of this version, it was raised to 256.|
|Java Edition Beta|
|1.6||Test Build 3||Solid 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 turned black.|
|July 19, 2011||Notch, 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.|
|1.8||Pre-release||The player's view distance decreases in lower altitudes.|
|Previously, the sea level was at layer 64. Now, it is at layer 63. Worlds created before this update generate one-block-high "waterfalls" at the boundary between previously-generated terrain and new, post-Beta 1.8 terrain.|
|1.2.1||12w07a||The height limit was doubled from 127 to 255, though 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.|
|1.7.2||13w36a||Amplified world type added (attempts to use the full 255 height).|
|1.11||16w32a||The 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.|
|1.0.0||alpha 0.17.0.1||The height limit was doubled from 127 to 255, with the exception of the nether and old world type. However, terrain (except structures) generates only up to the old height limit.|
- The highest possible altitude the player can legitimately climb to is Y=256, 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.
- Block generation and player construction below and above the build limits can only be achieved through mods, such as the Cubic Chunks mod.
