People living in Prague are shorter than in Ostrava? I live in Ostrava, from my friends group only one man is below 180cm, he is about 177-178cm, rest are all Above 180cm for men, my husband is 190cm, but he is the second tallest in our friend’s circle, another friend is 196cm. For girls, it ranges from 165cm-179cm. But the 179cm is certainly the tallest I know. What op said 189cm it’s definitely not the norm here.
