Player movement

Jumping is how players and mobs go up blocks. Players and most mobs can jump up 1 block at a time (more precisely, 1.252). Jumping is not needed for differences in height of 1/2 block or less. The default key for jumping is the space bar, which is also used for swimming. Jumping uses more hunger than walking. Sprinting and jumping is faster than normal sprinting, but it uses much more hunger.

Players move at a speed of 4.317 m/s while on flat ground. Sprinting increases this to 5.612 m/s. Players flying in creative mode reach a speed of 10.89

Movement
The player walks at a rate of about 4.317 meters (blocks) per second. This means that the player can walk a total of 5181 blocks (5.2 km) in one Minecraft day.

The player is able to sprint, draining the food bar considerably (10×) faster than usual while doing so. The player is capable of sprinting approximately 5.612 blocks per second, as opposed to the regular pace of 4.317. The player can jump four blocks horizontally when sprinting. The player cannot sprint if there are only 6 points or fewer left in the hunger meter. Sprinting is activated by double-tapping the forward key (default ) then holding it, or by pressing the sprint key ( by default).

Sneaking is a feature activated by holding the sneak key (default is ). Sneaking prevents players from falling one or more blocks, making it highly useful for building horizontally outwards over empty space. If you are past the edge of a block and you stop sneaking, you will not fall off of that block. Additionally, the player can still dismount blocks while sneaking by jumping over the block's edge.

In Creative mode, the player flies at about 10.89 blocks per second.

The maximum height a player can jump without the "jump boost" effect is about 1.252 blocks.

Trivia

 * Walking on soulsand will make the player's movement slow.
 * Double clicking the spacebar in Creative Mode is how you fly. Flying is an easy way to get around, as you can cover vast distances quickly.
 * The player (and most mobs) jumps about 1.252 blocks high.
 * The Jump Boost status effect increases this to 1.836 blocks, and Jump Boost II increases it to 2.517 blocks.
 * Spiders jump to attack, but these jumps only raise them to a height of 1.153 blocks.
 * Slimes and Magma Cubes move only by jumping.
 * Magma Cubes' jump height depends on their size: 1.836, 2.517, and 4.154 blocks for tiny, small, and large respectively.
 * The number of jumps you make is recorded in Statistics.
 * Jumping on crops can harvest them, but at the cost of turning farmland back into dirt.
