Depends on the origins, as far as I can tell a lot of recent occurrence the "must be 6ft tall" is socially driven by dating app use (which enables more nuanced selectivity). For much of history (pre-industrialization) men weren't often as tall due to begin with, due to more prevalent nutrient deficits. Additionally, rather than trawling a site with thousands of men you were largely limited by your location for potential suitors, so you simply couldn't be as picky (if you had a choice at all, as women often didn't). I generally find that people need to be much more careful when discussing these kinds of topics. People are very quick to attribute certain attributes of desirability to biology, and there are no doubt common threads amongst humanity, but there have also been enormous swings in social trends that have ignored these factors.
