Block



Blocks are the basic units of structure in Minecraft. Together, they build up the in-game environment and can be mined and utilized in various fashions.

Textures
The textures on the faces of blocks are 16×16 pixels by default, but players can utilize resource packs that increase the resolution allowing textures to be 32×32, 64×64, 128×128, 256×256, 512×512, or (rarely) 768×768, 1024×1024 and 2048×2048 pixels. No matter what the resource pack, however, each block is proportionately one cubic meter. Most blocks have static textures, with the exception of water, lava, portal, fire, sea lantern and prismarine blocks, which have a shifting pattern for each face. All blocks, with the exception of sand, red sand, gravel, anvils and dragon eggs, ignore gravity.

World-generated blocks
Entries marked with a D require additional data values to fully define the block in the world. Entries marked with an I have a different ID as an inventory item. Entries marked with a B require additional inventory data to fully define the inventory item. Entries marked with a T have tile entities associated with them to store additional data. Items with IDs in red cannot be legitimately obtained by the player in the game; they can only be obtained using commands. Items available only in Creative mode are in blue. Items only obtainable through the Silk Touch enchantment in survival mode are in green. Items only obtainable through external programs are in orange.

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

Naturally created
These are blocks that were created by natural events, such as water and lava creating obsidian.

Structures
Same as "naturally generated", but these blocks are created with the "generate structures" option enabled.

Structures
These blocks are generated as part of Nether fortresses.
