- For the CPU Mode, see Jump (CPU Mode).
Jumping is an action that moves a character from the ground into midair. It is performed by pressing up on the control stick/d-pad, the X or Y buttons with the GameCube and Classic Controller, or the C button on the Wii Remote and Nunchuk. All characters can also jump a second time in midair, providing they are not attacking, air dodging, helpless, in hitstun, or have used it already.
There is a short delay between the jump button being pressed and the on-screen character actually jumping, during which the onscreen character will enter a crouching portion of their jumping animation. If the control stick or jump button is released during this time, then the character short hops. If the control stick is tilted backwards during this time, the character will jump backwards with a different animation than a regular jump. If the standard attack button is pressed during this time, then the character uses their up smash (but only if the jump was executed with the control stick). Because characters can jump while shielding (excluding Yoshi, who has a unique shield), this allows usage of up smashes (and up special moves as well) without having to drop the shield. This also makes it difficult for a player using the Wii Remote-only control scheme to perform up tilts. Inputting an aerial on the first frame that a character is airborne will cause the jump to be slightly lower, because gravity applies to the first frame of an aerial but not to the first frame of a jump.
 Jump height ranking
Below are lists ranking characters by how high they jump. Note that this list only measures their first jump; the second (and so on) and third jumps are ignored.
The following is a ranking of the characters in Super Smash Bros. based on how high they jump from the ground.
