Reason: On 1.17 snapshots Skulk detection when jumping while sneaking

Jumping is a mechanic that elevates the player14 block into the air. It also has other effects when combined with another forms of movement.




Jumping is done by pressing the jump key (which defaults to the space bar on PC) or the jump button on other devices (for example the 'A' button on Xbox). If auto-jump is on the player jumps whenever they brush up against the edge of a block.


Jump height changes

Jumping normally lets the player climb up 114 block. Players with Jump Boost I are able to jump 11516 block, and with Jump Boost II they are able to jump 212 blocks. The effect also increases more with more levels of Jump Boost.

Honey blocks make players jump 316 of a block from them, meaning that they get an 85% jumping reduction.


Cobwebs and sweet berry bushes prevent players from jumping from them.

Sneaking and crawling, when activated by suffocation prevention in Java Edition, prevent players from jumping due to the reduced space. These two actions normally do not prevent players from jumping.


Jumping can be combined with sprinting to increase the player's movement speed. This also reduces the hunger bar faster.

Other mobsEdit

Certain mobs are able to jump:


  • Jumping was one of the first transportation mechanics added.
  • The highest possible distance a player can jump without effects is over 9 blocks, using ice momentum under a 2 block ceiling.
