A block can be considered solid if it has a collision box that players, mobs, or other entities cannot move through. For a block to be solid it also has to not be broken by flowing liquids. Blocks such as iron blocks are solid, and cobwebs are non-solid, because players can move through them slowly and water flow can break them.
Solid blocks are also considered when generating structures.

Reason: There are new block in 1.18.1
List of solid blocks
The following blocks are all solid blocks. They are categorized by their material.
|Wood||[[Mangrove Wood Planks|[[Mangrove Wood Slab||
List of non-solid blocks
These blocks consist of any block that is not solid.
|Replacable water plant|
Reason: List the ones in bedrock edition (due to a bug, they are different)
They are more block height
Most solid blocks are 1 meter high, but certain blocks have non-standard block heights.
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. From ground level, this is anything the height of a chain or less.
A player can fit through spaces as small as 1.8125 (2 - 3⁄16) blocks high, since players are 1.8 blocks tall. This allows players to fit through a 2-block gap with a floor as high as a trapdoor.
When sneaking, a player can fit through spaces as small as 1.75 (2 - 1⁄4) blocks high,[Bedrock Edition only] or 1.5 blocks,[Java Edition only] since sneaking players are 1.65 blocks or 1.5 blocks tall, respectively. In Bedrock, this allows players to fit through a 2-block gap with a floor as high as 3 layers of snow. In Java, players can fit through a 2-block space with a floor as high as a slab.
When gliding with elytra, a player can fit through spaces as small as 0.625 (1 - 3⁄8) blocks high, since gliding players are 0.6 blocks tall. This allows players to fit through a 1-block gap with a floor as high as 4 layers of snow, or a flower pot, or a daylight sensor.
Note that doors, although appearing to be one 2-meter-high block, are actually composed of two (top and bottom) 1-meter-high blocks.

- These blocks are also thinner, i.e. their length and width are less than that of a full block.
- Soul sand has inner collision boxes every eighth of a block, so there is a collision box at 1/8, 1/4, 3/8, 1/2, 5/8, and 3/4
|Java Edition pre-Classic|
|Cave game tech test||Added grass block, stone, and air (which was not considered a block at the time).|
|Solid blocks were the only available type of block, until rd-161348, when the first legitimately-obtainable non-solid blocks (saplings) were added.|
