With a total height of 829.8 m (2,722 ft) and a roof height (excluding antenna) of 828 m (2,717 ft), the Burj Khalifa has been the tallest structure in the world since its topping out in late 2008.[4][9]
World Trade Center (1973–2001) When completed in 1972, 1 World Trade Center became the tallest building in the world for two years, surpassing the Empire State Building after a 40-year reign. The North Tower stood 1,368 feet (417 m) tall and featured a telecommunications antenna or mast that was added at the top of the roof in 1978 and stood 362 feet (110 m) tall. With the 362-foot (110 m)-tall antenna/mast, the highest point of the North Tower reached 1,730 feet (530 m).[89] Chicago's Sears Tower, finished in May 1973, reached 1,450 feet (440 m) at the rooftop.[91] Throughout their existence, the WTC towers had more floors (at 110) than any other building.[89] This number was not surpassed until the advent of the Burj Khalifa, which opened in 2010.[92][93] Each tower had a total mass of around 500,000 tons.[94]
