Once a gecko, reaches 1 year, they're pretty much full grown. Usually anywhere from 7-11 inches (top end of that scale, is usually giants + Super giants)
If you're asking for breeding purposes, general rule of thumb is 50g's +, but 60+ is even better.
yeah, that doesn't answer anything, im asking how big they get when they are fully MATURE, not just how big they get. maybe they are fully mature when they are not fully grown.
TUG says that they breed females starting at 38 grams, and that there is an 8 month period going from "egg to egg"(after coming out of the egg, there is an 8 month period before they'll lay eggs), at least that's what I was told by them.
I waited until the early-mid 40 gram range, but would base it more on the shape and size of the gecko, as opposed to weight alone.

Are you talking about fully mature for breeding or fully mature as in max out in size? I still believe geckos grow to their full potentials in 1.5-2 years; you see rapid growth in the first year, then slowly build up more later on. Every gecko is different, a fully mature gecko can be anywhere from 60g to 130g (non-giant).
