There is no age/ size chart simply because they all grow at a different rate, it depends on the size out of the egg, how soon it was started, prey size, feeding schedule, fasts, metabolism etc, etc.

What you want is an animal that appear healthy and well proportionate.

A little advice on feeding, hoppers are usually used to start hatchlings, from then the snake moves quickly to small and/or adult mice, so at this point you might want to use bigger preys.
