A 12 inch trout is usually between two and three years old, though this varies depending on the environment they feature in. Trout grow very quickly in the first two to three years of their life, and then their growth rate slows. In some cases, trout can reach 10-12 inches in under two years, and some larger trout can reach 12 inches in as little as one year. In waters where food and conditions are not ideal, it could take up to three years for a trout to reach 12 inches.
