美国青少年男女平均身高体重 (最新数据)

For girls, growth slows and levels off at 16 (but a girl will gain another 10 lb in weight while only grow 0.3" taller in the next 4 years)

For boys, that time happens at 17 but there is more chance to grow a little taller onwards.

At 20, average girl is almost 5' 4 1/2" tall, while boy is 5' 10".

So an average gap between GF and BF is about 5 1/2", which is like 13-14cm. (男女身高差之黄金比例？)
