* No Consistent Power Level: The Hulk's strength is notoriously inconsistent. He can be incredibly strong in one story and much weaker in another. This makes his jumping ability also fluctuate.
* Different Writers & Universes: Different writers have different interpretations of the Hulk's powers, leading to variations in his feats.
* Plot Demands: His jumping abilities are often adjusted to fit the needs of the story. Sometimes he needs to jump incredibly high, while other times he just needs to leap over a small obstacle.
Here are some examples of Hulk's jumping feats:
* High Jumps: In some stories, he's shown jumping miles into the air, reaching the top of skyscrapers with ease, or even leaping into orbit.
* Limited Jumps: In other stories, his jumps are more modest, perhaps only a few hundred feet.
It's safe to say that the Hulk's jumping ability is essentially unlimited within the confines of a given story. The only real limitation is the writer's imagination.
Bottom line: The Hulk's jumping ability is incredibly variable and depends heavily on the context of the story.
