In an answer about Spidey vs. Doc Ock, we learned that Spider-man is actually one of the stronger Marvel super-heroes. It's also often stated that he has the proportional strength of a spider, but that amount tends to vary by writer/spider.
However, since he's so strong, I wonder how high he can leap. Can he leap tall buildings in a single bound? Short buildings? Just buses?
An exact value isn't necessary if it's not available; an inference based on examples, physics(!), or in-universe comments is fine.
