Will a 20-year-old boy still grow taller?

We often hear that girls grow up to 18 and boys grow up to 20. Is this not the objective fact? I can assure you that such a view is definitely a fallacy! Whether a person can still grow taller is not determined by age, but by whether the growth plates of his long bones and spine are closed. So can a 20-year-old boy still grow taller?

Can a 20-year-old boy still grow taller?

Whether a person can still grow taller, the level of development and age of a person are not necessarily closely related. Whether a boy can grow taller when he is 20 years old depends on whether the epiphyseal ends of his long bones are closed. If the epiphyseal ends are not closed, he can continue to grow taller. To determine whether the epiphyseal ends are closed, you can go to the orthopedic department of the hospital and take an X-ray. If the epiphyseal ends of the long bones are already closed, you can no longer grow taller. If you want to grow taller, you should pay attention to supplementing nutrition during puberty and growth and development, especially supplementing calcium and zinc, drinking more milk, and eating more high-protein foods for nutrient deficiencies. In addition, you should get more sun and do more exercise, such as playing basketball, volleyball and other fitness sports, which are very helpful for growing taller.

Height formula

Adult height of young man = (father's height + mother's height) Periodontology 1.08 Obstetrics and Gynecology 2

Adult female height = (father's height x 0.923 + mother's height)

This calculation method is a genetic formula, so it does not take into account the influence of environmental factors, and the error is about 3 to 5 cm. In addition, some parents' heights may not reach the genetic standard height due to the influence of environmental factors in their childhood, so the genetic height of parents should be calculated from the height of their elderly.

So why do we need to calculate our genetic height? In fact, genetics is a scientific evidence of whether we can continue to grow taller. We can calculate our own genetic height to know whether we still have room to grow taller and how much room we have! The factor of natural genetic variation is not within our calculation range!
