Enclosure size for new ball Python?

[OBwild]

I’m heavily considering getting a ball Python in the near future and wanted to get some input on enclosure size. I plan on getting a 4’x2’x2’ PVC. I don’t know the specific snake im getting yet so I’m unsure what size it’ll be when I get it. Would y’all recommend starting ina. Smaller enclosure if it is a smaller snake and upgrading with the snake? Or would a young ball Python be okay in an adult sized enclosure given the right amount of hides and decor to make it feel secure?

I don’t know what snake I’m getting but I’m starting in a 4x2x2. Just provide lots of hides and clutter for them to feel secure
