Actually the Wikipedia page about average height in the world is very good.
For exemple German average is something between 5-9 and 5-10. So far from the stereotype of tall blonde people of 6'3
And yes, I confirm, european average (developed countries in general so I include Korea and Japan) are exagerated
But it's not the case of my country, french official average is 174,5 (and a few cm more if you include only young people, of course) and it's totally accurate with what I see. And don't forget that my country is multiracial with north african people but also tall and short african ethnicities (I see both, but where I live African are the shortest -Comorian, Ivorian and Congolese- but I know that Senegalese for instance are among the tallest in Africa).
When I talk to strangers from northern Europe or Eastern Europe, they always tell me that French are shorties and tanned people (while I'm very white for instance). It just irritate me a lot when their country is just one inch taller in average than us at very best. Sometimes not even.
The study about dinaric average has been made in ONE VILLAGE only
Look. The Dutch average on the Wikipedia page is only 181 cm and SELF-REPORTED (so usually inflated by one or two cm like the UK average). We are far from the stereotype of very tall Dutch . So, where come from the idea that all Dutch are like 6'5 ? I just suspect people to voluntary exagerate
It's like, when I claim that Flemish average is about 5-9/10 people look at me like if I was crazy telling me that it is 6ft at least
A list of non-european people who can rivalize in average with them : South Sudanese, Senegalese, North Indian (Punjabi, kashmiri), Polynesian, Rwandese Tutsi, Chadian, and probably more I don't know etc
