Ok, dumb question..

But never painted anything larger than a small dorm room. I want to paint a couple of rooms in my new townhome but have no clue how many gallons of paint to buy. And once they mix them you can't return the paint...

So is there some rule or is it just a SWAG (Scientific Wild Ass Guess)

It'll say on the can. Buy an extra gallon or at least an extra quart.

Do not trust what HD or Lowes tells you, you will always come up short. Use a good tint based primer as well. Will make life way more easy. The SWAG is based on new walls? Old Walls? Sheen? etc...

Good luck.

And get a few empty cans w/lids and mix all the paint (of the same color) you buy together so it has the same tint.

(you would be surprised how different the actual tint can be from identical cans of paint)

I recollect about 400 sq. ft. per gallon. But thats a SWAG you can use until a better answer comes along.

400 always worked for me when I used to be a painter.

+1 altho the can usually says 450, they don't.

1 coat paints aren't.
