Generally speaking, the standard height of a boy at the age of 16 should be around 170cm. However, this height is not an absolute standard, because height is related to many factors, such as genetic factors, acquired nutritional supply, work and rest habits, and sports and exercise. If a child can maintain more than 8 hours of effective sleep every day, does not smoke or drink, has a balanced diet, can ensure that they are not picky eaters, and enjoy exercise in their daily lives, they will generally be taller than expected.
