But even the UK is much taller than the global average and you’d be short at 170cm.
In any case, I don’t really see the region as being relevant; the meme may be limited to a particular region, but I was objecting more to the whole notion of that stereotype. Which is the same regardless of the unit used.
How tall or short you’re considered is dependant on that region. People are comparing you to the people around you, not to global average.
