List of tallest structures

The tallest structure in the world is the Burj Khalifa skyscraper at 828 m. 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 List of tallest buildings and structures, List of tallest freestanding structures and List of tallest buildings and List of tallest towers for additional information about these types of structures.

Terminology
Terminological and listing criteria follow Council on Tall Buildings and Urban Habitat definitions. Guyed masts are differentiated from towers – the latter not featuring any guy wires or other support structures; and buildings are differentiated from towers – the former having at least 50% of occupiable floor space although both are self-supporting structures.

Lists by height
These lists include structures with a minimum height of 500 metres (1640 feet). The lists of tallest structures from 400 to 500 metres and from 300 to 400 metres include shorter structures.

For all structures, the pinnacle height is given, so the height of skyscrapers may differ from the values at List of skyscrapers. Tension-leg platforms are not included.
