How do you know when something is too small.

I read somewhere that a good rule of thumb for sizing a tank or tub is 1 square foot of floor space for each linear foot of snake. That would mean that a 6 foot snake should have 6 square feet of space (3'x2' or 4'x1.5'). Somebody correct me if I am wrong.

I've read the same thing.
