When will my baby grow up?

I was just curious how long it generally takes a Ball Python to reach close to their full size? I have a yearling so I know this is a premature question but I'm sure others wonder the same thing.
Thanks!

3 years and you'll have a fill sized adult. Sometimes as short as two!

Wow! Thanks! That's way faster than I thought - now i'm all excited!

Then again, from what I've read, they technically never stop growing. It just slows down extremely significantly. It really all depends. Feeding and other factors.
