Most are a half hour but some aren't.
Most of the episodes are a half hour.
SpongeBob the last Stan is 30 min. long
Unless it is a special about 11 minutes
The episode was too long with that scene in it
Each episode is a half hour. Sometimes it's longer and sometimes it's shorter.
That is a matter of opinion, and as such, there can be no correct answer. However, I would say that there are a lot of worse cartoons out there; if Spongebob was the worst, it wouldn't have gone on for as long as it has.
Typically 21-23 minutes.
