How long from Froglet to Adult?

[LilyPad]

My gray tree frog has made an incredible growth spurt in the last few weeks, not just fatter, but bigger all around. I have no idea what her age was when I got her, I was told she was a "juvenile" tree frog. How long does it generally take for a tree frog to go from froglet to adult? Should I expect her to continue growing at this rate and stop soon? Or will it slow down and take time for her to reach adult size.

I'm not sure about Gray tree frogs, but most tree frogs seem to grow pretty quickly.
