Solid block

Comparison of the solid stone and liquid water blocks

Solid blocks are a category of block.

Properties

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:

• 
  Painting
• 
  Item frame
• 
  Head
• 
  Sign
• 
  Banner

Other block-dependent blocks may be placed only on full, opaque solid blocks (with a few exceptions):

• 
  Torch
• 
  Redstone torch
• 
  Button
• 
  Lever
• 
  Ladder

Solid blocks are also considered when generating structures.

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 boat 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 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:

			Fences, cobblestone wall

			Cactus
0.875	7⁄8	14	Soul sand, 8 layers of snow
			Chest, ender chest, trapped chest, top of brewing stand
0.8125	13⁄16	13	End portal frame without eye of ender
			Chorus plant
0.75	3⁄4	12	Enchantment table, 7 layers of snow
			Cocoa bean plant, head on wall
0.625	5⁄8	10	6 layers of snow
			Inside of hopper, sideways-oriented end rod
0.5625	9⁄16	9	Bed
0.5	1⁄2	8	Bottom slab, 5 layers of snow
			Head on ground, bottom part of stair, cake
0.375	3⁄8	6	Daylight sensor, 4 layers of snow
			Flower pot
0.3125	5⁄16	5	Inside of cauldron
0.25	1⁄4	4	3 layers of snow
0.1875	3⁄16	3	Bottom trapdoor
0.125	1⁄8	2	Base of brewing stand, redstone repeater, redstone comparator, 2 layers of snow
0.09375	3⁄32	11⁄2	Lily pad
0.0625	1⁄16	1	Carpet
