Why heterosexuals are so obsessed with height in online dating

Mashable 

In the economy of heterosexual online dating, where thumbs wield the ultimate power over a person's love life, height appears to be an immensely valuable currency. The listing of height in dating app profiles has become so prevalent, that many swipers come to expect it, and sometimes hypothesise when it's been omitted from the profile. In my own experience, I have grown to attach a great deal of importance to the feet and inches in a person's bio. As I idly swipe through Bumble, I will scroll through a dater's photos before perusing their bio, searching for a number that might dictate the crucial decision: to swipe left or right? I'm 5ft8, and I often swipe left (which means no) on men under 6ft.
