They don't stop growing, or they would stop sheddingYou will find with most snakes the time frame in which it can take to stop growing can be anywhere between 3 and 6 years. "On average." No one can really give you a percise time frame because cornsnakes growth pattern tends to be depicted on their feeding scedule. Once every 5 days or so usually holds a kinda standard 3 to 6 year average growth. While more frequent feedings lead to a much faster rate but can also land in obesidy and other problems being a snake needs at least 3 days to fully process a meal. The less you feed the less they grow. This is why it is allways vital to keep up with the charts of as a snake grows when the diet size needs to be changed.
