What Size Should A Gecko Be?

  I Have A 5 month 2 day gecko it weighs just over 18 grams and is 5 inches big is this a good size for a gecko of this age?
Like they said before depends on the gecko ignore the person tht said give it back it sounds pretty ok to me but wat gecko is it??
Huff .. Thats fine for a geko but you should know that other wise you are a crp geko owner and should give the poor thing back to the store before you kill it !!!!
depends what kind of gecko it is. sounds fine though
