Can't figure out how old beardie is!

[goldie1]

We have had Goldie for 2 months and she is growing very well and adapted to life with us but I am unsure Of how old she is? and
At what age is a beardie considered an adult?

Goldie is currently 14.5 inches long from head to tail.

 

[TheWolfmanTom]

Dragons mature within 1.5 to 2 years old.
Its almost impossible to guess age by size.
I have 9 month old juvi's that are 18 to 19 inches long.

Like Tom said, it's anyone's guess. My baby (5 months) is 18", while my 3 year old female is only 15". Did the people you got your dragon from not have any idea as to the age?
