Penguins typically stop growing and reach their full size by around 1 to 3 years of age, depending on the species. For instance, Emperor penguins take about 3 years to reach maturity, while smaller species like the Little Blue penguin may mature in just 1 year. After this period, they focus on gaining weight and developing their adult plumage rather than growing in size.
