Solid blocks are a category of block.
A block can be considered solid if it has a collision box that players, mobs, or other entities cannot move through; those caught inside a solid block may suffocate. The only exception to this is the cobweb, which, although considered solid, can be moved through, albeit slowly.
The collision property[Verify] of solid blocks allows block-dependent blocks and entities to be placed upon them, including:
- Item frame
Other block-dependent blocks may be placed only on full, opaque solid blocks (with a few exceptions):
Solid blocks are also considered when generating structures.
List of solid blocks
Here is a list of solid blocks, categorized by their material.

Most solid blocks are 1 meter high, but certain blocks have non-standard block heights.
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 or less.
When sneaking, a player can fit through spaces as small as 1.75 (2 - 1⁄4) blocks high, since sneaking players are 1.65 blocks tall. This allows players to fit through a 2-block gap with a floor as high as 3 layers of snow or less.
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, or less.
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:

|0.09375||3⁄32||11⁄2||Lily pad [note 2]|
- Although boats are an entities, players can step on them.
- These blocks are also thinner, or put another way, their area having this non-standard height does not cover the width/length of a full block.
|Pre 0.0.0||Added grass blocks and cobblestone, the first two types of solid blocks.|
|Solid blocks were the only available type of block, until rd-161348, when the first legitimately-obtainable non-solid blocks (saplings) were added.|
