Most snakes are pretty sedentary and really don't move about that much. I will say that I don't keep hoggies so I'm not sure about their activity levels but my 4ft kings did just fine in a split T8 with a shelf. They were in 40g tanks prior to that but they weren't using much of the space. I originally ordered 4x2s for them but saw it was a waste of space so my bulls and carpets went into them. Those are all 6ft- 8ft animals and they're in the 4x2s comfortably even though I want more vertical space for the carpets so they may get 4x2x2s instead of the 4x2x1s they're in now. My carpets spend more time perching and actually leave a very small cage imprint. My bulls and olive are my most active snakes and again their 4x2s give them room to roam. My olive will end up in a 6x2 or 8x2 just because he does move about a lot and uses more areas of his viv. He'll also potentially be in the 10-12 ft range. My snakes also get out of their enclosures regularly to stretch all the way out and even then they don't travel far or fast.
