It’s more about nutrition and genetics.

Calories and macros in childhood is very critical to how people grow.

Denmark, Netherlands and I think Serbia have some of the highest average heights in the world. It's nothing to do with the size of the nation, it's genetics and nutrition.

Genetics and nutrition are the key, many smaller nations have high average heights

Other people have already mentioned nutrition, which is very important. But scientists have also theorized that part of the reason for the Netherlands having the highest average height is that women in that country have preferred men who are taller, more than in other countries.

In response to your question, I don’t think so, that would be very strange. The only way I could think of that the size of a country and the height of its people would correlate is if bigger countries tend to have higher GDPs per capita, allowing people more money so they can get proper nutrition from food. However, I don’t think size of country and GDP per capita correlate much, but I could be wrong.

It's genetics, nutrition and doing things that optimise growth hormone that effect it. Taller parents will have taller kids generally. Countries that eat alot of dairy like Netherlands, Montenegro, Minnesota in US - tend to be taller. Countries like China increased height by 2-3 inches in school districts with mandatory milk programmes. milk increases Insulin like Growth Factor and has a very slow digesting protein (casein).

In the Netherlands they found that immigrants from Moroco and China had children that grew to the average height of the country probably by eating more similary to the Dutch.

During excercise and sleep growth hormone is released, it is reccomended that teens get 9 hours.

That would explain why I’ve always imagined the Pope to be as small as a Lego figure

> > Does our body grow to the length of the territory(county) we are born at? Like think about it America and Russia have a big territory and their populations height and weight are way bigger compared towards other small countries like Nepal, Eritrea, Israel were their population height and weight are comparatively small. Like any other species shade their skin or add more fur in cold weathers, do our body know what suitable height and weight is to adapt to our surrounding?
