Solid block

Comparison of the solid stone and liquid water blocks

Solid blocks consist of any type of block that has a collision box that players, mobs, or other entities cannot simply move through, and have to move on top of it or around.

Properties

Mobs require a solid top surface to spawn. Some mobs are able to spawn inside of the space occupied by another block, but only if their hitbox does not intersect the collision of any solid block.

Players, mobs, and other entities can walk on top of solid blocks. Particles that are affected by gravity (e.g. slime particles or water drip particles) also collide with solid blocks.

Full blocks

If a solid block's collision box is a full cube that is solid on all sides, it is known as a full block. For example, stone, planks, and glass are full blocks, but stairs, fences, and chests are not. For most blocks, it's easy to tell whether they're full blocks or not, but some are not so obvious:

Cauldrons and composters are not full blocks because their top face is not fully solid.
Scaffolding is not a full block because although its interaction box occupies the full block, its collision box does not.
Dirt path and farmland are not full blocks because they are slightly shorter than a full block.
Mud and soul sand are not full blocks despite visually appearing to be because their collision boxes are shorter than their models, so entities standing on top "sink into" the blocks.

Whether or not a block is a full block can influence some game mechanics. For example, endermen will only place blocks on top of full blocks and hoppers will not try to collect item entities if their top face is covered by a full block.

↑ Hanging signs' mounting bracket is always solid.
↑ The top part is solid when standing on it, otherwise, players can phase through it by the sides.

Height

This section needs to be updated.

Please update this section to reflect recent updates or newly available information.
Reason: List the ones in Bedrock Edition (due to a bug, they are different)

Most solid blocks are 1 block in height, 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 (²⁹⁄₁₆) 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 1.5 blocks, since sneaking players are 1.5 blocks tall, respectively. 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 (⁵⁄₈) 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, a flower pot, or a daylight detector.

Note that doors, although appearing to be one 2-meter-high block, are actually composed of two (top and bottom) 1-meter-high blocks.

Here is a list of blocks with non-standard heights, from tallest to shortest in height:

Width

Many blocks are less than 1 meter wide on one or more sides.

The table below shows the widths of various blocks. If a block has several hit boxes of different sizes (for example: brewing stands), then each hitbox is listed separately. Blocks with sides of different widths are listed with cardinal directions (north, south, east, west) for each side, assuming that the block was placed from above, with the player facing north.

History

Java Edition pre-Classic
Cave game tech test							Added grass block, stone, and air (which was not considered a block at the time).
Cave game tech test							Solid blocks were the only available type of block, until rd-161348, when the first legitimately-obtainable non-solid blocks (saplings) were added.
