The B1M
Skyscrapers are the most iconic part of any citys horizon. New ones grow up all the time, always contending for the “worlds tallest.” This video shows that height isnt the only stat that matters: Total location does, too.
The video goes on to look at some of the highest structures across the globe and compare them using their total area instead.
