How big is the bowling lane?

[folcon]

I don't have university life yet, but am working on a build right now.  I plan to add my own bowling alley later once I have UL.  So I was wondering how big the lanes are so I can be sure to reserve enough space to put in maybe 4 lanes once I get the expansion.  So what is the footprint size I guess is my question.

It looks like 3 wide by 12 long .
