If a 10 year old boy is 152cm tall how will he be when an adult?

It is difficult to predict precisely how tall a 10 year old boy will be as an adult, as there are multiple factors that influence growth, including genetics, nutrition, and overall health. However, a general estimation of adult height can be made using various methods.

Mid-parental height method: This method involves calculating the average of the height of the child's biological parents and then adding or subtracting a certain amount based on the child's gender. For boys, 13cm (5.1 inches) is added to the average parental height; for girls, 12cm (4.7 inches) is subtracted.

Applying the mid-parental height method:

1. Assume the father's height is 182cm and the mother's height is 170cm.

2. Calculate the average parental height: (182 + 170) / 2 = 176cm.

3. For a boy, add 13cm to the average: 176cm + 13cm = 189cm.

4. Therefore, the estimated adult height for the 10-year-old boy would be 189cm (6' 2").

It's important to note that this is just an estimate and actual height may vary due to various factors. Regular check-ups with a healthcare provider can provide more information and guidance on growth and development.
