Blocks are the basic units of structure in Minecraft that can be directly placed in the game world.
Blocks are arranged in a three-dimensional grid of 1-cubic-meter cells. Each cell always contains exactly one block. The only exception to this is snow layers[Bedrock Edition only], which can be combined up to eight in a cell.
Together, blocks and fluids build up the in-game environment, and most can be harvested and utilized in various fashions. Some blocks, such as dirt and sandstone, are opaque and occupy their entire cubic meter, while other blocks, such as glass and flowers, are transparent or non-solid. Explosions destroy some blocks more easily than they destroy others.
Some blocks, such as torches and glowstone, emit light. The amount of light they emit varies widely; see this table of light values for further information. Opaque blocks completely block light, while transparent blocks can have no effect on light, block the light, or merely weaken it.
A player can automatically step up from a lower to a higher height if the difference is at most 0.6 (3⁄5) of a block or 1.9685 feet.
Also, the world height limit is 256 blocks/meters (839.895 ft).
The textures on the faces of blocks are 16×16 pixels. Most blocks are proportionately one cubic meter by default, but their shape can be changed using models.
Most blocks have static textures, but these blocks are animated: water, lava, Nether portal, End portal, End gateway, prismarine (slab; stairs; wall), sea lantern, magma block, seagrass, kelp, fire, lantern, lit campfire, lit blast furnace, lit smoker, stonecutter and command block.
Using resource packs, the player can change the textures and resolution of blocks, including whether their texture is animated. They can also change the shapes of blocks using models and the size of blocks to any size with equal width and height, though sizes that are a power of two tend to work better.
List of blocks
Bedrock Edition/New Nintendo 3DS Edition only
These blocks can be accessed only in Bedrock Edition and New Nintendo 3DS Edition. In these versions, item frames work as block entities, stonecutters are obtainable only from creative mode inventory, through commands, or by inventory editing, and glowing obsidian, Invisible bedrock, and nether reactor cores are not obtainable at all but continue to exist in old worlds.
Education Edition (mobile) only
Removed blocks no longer exist in current versions of the game.
Technical blocks are blocks whose main functions are strictly tied to the usage of other blocks. They cannot be acquired through normal gameplay, most of them cannot be obtained with commands and even external editors[Java and Legacy Console editions only], but other ones require commands or mods to obtain. They serve various purposes during events within the game. If acquired, they usually have a missing texture.
Many of these blocks have different representations in the inventory; flint and steel is used to place fire, water and lava can be placed with their respective buckets, and blocks such as beds, doors, cake and flower pots have separate inventory items.

- Certain blocks may interpret positions they cannot be placed in by normal means as a valid position. For example, a sign placed in midair via
/setblockor through remains in midair even when updated, until either it is broken, or a block is placed below it and broken.
