I’m 15, male, and 5’1. My dad is about 5’6 and my mom is 5’0. My Tanner stage according to my doctor is 3. When I put the info in your calculator, it said 3.8. Will I be ever tall as my dad?
Stage 3 is when a boy grows the fastest. Thus, 3.8 says you should be growing rapidly at this time. How much you should be growing is something I cannot tell.
In general, boys grow to a minimum of the average of their parent’s heights. Therefore, you should reach at least 5’3 by the time you finish growing (which will be over two years from now). You are likely to be taller than that. Whether you’ll reach your dad’s height is something I have no way of predicting.
