A Block is a basic unit of structure occupying space in the world.


A Collision Box is a solid volume of space that the player is not meant to pass through, which consists of one or multiple Bounding Boxes, which are axis-aligned cuboids. Entities have their own bounding box, but are not treated as solid space (except for boats).

  • Not to confuse with a Hitbox, which is a volume of space that a player can interact with (attack, mine, right-click...).
  • Also not to confuse with a Model, which is simply the graphical representation of a block / entity on screen.
  • Finally, some blocks have their own "effect box", such as fluids, ladders, cacti, pressure plates... All of which are coded and applied differently.


For example: a button has no collision box, as the player can walk through one, but has a hitbox which the player can click on.

Another example: a barrier block has overlapping bounding box and hitbox, but is hard-coded to have no model.



This article lists the collision boxes and properties of all blocks in 1.8.

Blocks with particular properties and/or no collision boxes are presented on their own articles.

Images were taken with Blockbench, or from the Minecraft wiki.

Soulsand 1 × 1 0.875 Looks like a full block, but is actually 2 px lower.

Slows down entities walking on top of it.

End Portal Frame 1 × 1 0.8125
Enchantment Table 1 × 1 0.75
Bed block 1 × 1 0.5625 The bottom doesn't look tangible, but it actually is.

Dragon Egg 0.875 × 0.875 1 Centered.

Looks drastically different from its collision box.

0.5 The full cake is centered.

Each bite takes away 0.125b from the West (-X)

Wall (2-adjacent) 0.75 × 0.75 1.5 Orientable (4 variants).

Adjacent blocks must be solid, walls, or fencegates.

Wall (1-sided) 0.75 × 0.5 1.5 Orientable (4 variants).

Adjacent block must be solid, a fences, or a fencegate.

Wall (default) 0.5 × 0.5 1.5 Centered.
Cocoa (big) 0.5 × 0.5 Low: 0.1875
