Question:
I was curious and looked at your Tanner stages descriptions. I read that a growth spurt happens at Tanner’s stage 3. How much height growth would the average boy gain from this point onward before they stop growing? I got a 3.1.
Answer:
A growth spurt happens during stage 3. For some boys, it is spread out and slower. For other boys, it comes suddenly and rapidly for a shorter period. The amount of growth can be from 3 to 8 inches per year during a growth spurt. In other words, it isn’t easy to predict. Use the Adult Height Calculators to get rough estimates of your final height.
