The tallest structure in the world is the Burj Khalifa, a skyscraper at 828 m (2,717 ft). Listed are guyed masts (such as telecommunication masts), self-supporting towers (such as the CN Tower), skyscrapers (such as the Willis Tower), oil platforms, electricity transmission towers, and bridge support towers. This list is organized by absolute height. See History of the world's tallest structures, Tallest structures by category, and List of tallest buildings for additional information about these types of structures.
Terminology Terminological and listing criteria follow Council on Tall Buildings and Urban Habitat definitions.

Lists by height This list includes structures of all types over 350 meters (1148 feet). For all structures, the pinnacle height is given, so the height of skyscrapers may differ from the values at List of skyscrapers, such as the John Hancock Center being ranked above the Empire State Building.
