To begin with, snakes never quite growing. They will continue to grow their entire life. Their groth rate will significantly slow down at about age 3 to 5, but they will still be growing.

Males will have a tendancy to be smaller, both in girth and length, when compared to a female.

It is difficult to say wether your snake has reached its slow down point or not. I would guess that he/she probably has about 1 to 1.5 years before he/she stops growing rapidly. But in all honesty, that previous sentance is nothing more than a guess. A lot has to do with the sex of the snake (which is unknown) and the genetics of your snakes parents (which is also unknown).

To give you my best guess, if your snake is a male, it will probably grow another 1 to 1.5 feet and gain some girth. If your snake is a female, it will probably grow about 2 feet and gain a substantial amount of girth. In both cases, the timeframe would be over the next 2 years, aproximatly.

Please remember, this is only my guess. The above statement is only what I think will happen.

Hope this helps,
