Question:

Hi,

I have a question. I am 16. The calculator says that I’m in Tanner Stage 4. How many inches of growth can a person have during Tanner Stage 4? How long does Tanner Stage 4 last?

Answer:

During stage 4, a boy usually adds 1 to 3 additional inches (2 to 8 cm). This stage lasts about two years. See Stage 4—Growth in Height Slows Down.
