Average vs Maximum snake size

[fazz]

Hello,

I am looking to buy a snake but I can only ever find the maximum size they get. I was wondering if anyone could give me the average size that the adult snakes of the following species grow to:
- Murray Darling Carpet python
- Woma
- Black headed python
- Spotted python

Any photos of you holding or showing the size of one of these snakes would be much appreciated too! If you can think of any other beginner snakes that grow larger than a spotted but do not usually grow over two metres that would be appreciated.
Thanks in advance =)

MD: 5-6ft (some localities only 4ft)
Woma: 4-5ft (some localities 6ft)
BHP: 6-8ft
Spotted: 3-4ft

Spotted pythons are smaller than MD and womas in girth
