How tall a boy can grow at the age of 16 166 depends on whether the child’s epiphysis is healed or not, and how tall he ends up is also related to genetic factors and acquired nutrition. Generally speaking, boys develop later than girls, and the growth period generally lasts until about 18 years old, but there are individual physiques that can continue to grow after 20 years old. Whether a boy can continue to grow needs to observe whether the epiphysis is healed, if the epiphysis has already healed at the age of 16, it will be difficult to continue to grow after that. The final height of boys is also related to genetics, if both parents are shorter, the child’s height will not be too high because of genetic factors; later exercise and nutrition will also affect the child’s height, so it is not possible to specify the specific growth of how tall. It is recommended to exercise more, ensure sleep, reasonable nutrition.
