How big will a corn snake grow to?

at a mature age the snake usually varies from 4 feet to 6 feet long but may be shorter or longer, the snake is usually almost full grown at 3 years. (this is not true, corn snakes can keep growing until they are ten years old!)

personally i have a albino corn snake and she is 2 years old and runnin about 2 1/2 feet right now. corn snakes usually stay skinny until around 2 1/2 to 3 years and then gain more girth. good luck =) hope i helped
