Height against age, Danish females. https://www.sundhed.dk/borger/sygdomme-a-aa/boern/illustrationer/tegning/vaekstkurver-piger-0-20/ My eldest daughter said: I hope my height will improve to become 170cm (5'7'') Let's have a look at growth curves. Growth accelerates several times during adolescence, so we can only guess. Above a growth curve for Danish females and a fair prediction she will become disappointed (by an inch). A predicted median height is 173cm (5'8'') calculated using the height of her mother and my own height ((father's height minus 13) + mothers height)/2. More precise predictions can be made through combination of anthropometric measures.
