Blocks are the basic units of structure in Minecraft.
Blocks are arranged in a grid, each cell of which is 1 cubic meter, and are snapped to it, which means a block cannot be in more than one cell.
Together, blocks and fluids build up the in-game environment and can be harvested and utilized in various fashions. Some blocks, such as dirt and sandstone, are opaque, while other blocks, such as glass and ice, are transparent.
Some blocks, such as torches and glowstone, will 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 either have no effect on light or merely weaken it.
Mostly, only one block can occupy a single grid cell at a time. The only exceptions to this are snow layers[Bedrock Edition only], which can combine with each other up to eight in a cell, and water, which can combine with most non-full-size blocks using a game mechanic called waterlogging.
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 also have static textures, though water, lava, Nether portal, End portal, End gateway, fire, sea lantern, command block, prismarine, and magma blocks are animated.
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
Blocks with a gray background cannot be obtained in the inventory.
Bedrock Edition/New Nintendo 3DS Edition only
These blocks can only be accessed in Bedrock Edition and New Nintendo 3DS Edition. In these versions, item frames work as block entities, stonecutters are only obtainable 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 will 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 will remain in midair even when updated, until either it is broken, or a block is placed below it and broken.
