Explore ten tallest buildings around the world
The non-profit international organization Council on Tall Buildings and Urban Habitat (CTBUH) was formed in 1969 and announces the title of "The World's Tallest Building" and sets the standards by which buildings are measured. It maintains a list of the 100 tallest completed buildings in the world. The organization currently ranks Burj Khalifa in Dubai as the tallest at 828 m (2,717 ft). The CTBUH only recognizes buildings that are complete, however, and some buildings listed within these list articles are not considered complete by the CTBUH.
In 1996, as a response to the dispute as to whether the Petronas Towers or the Sears Tower was taller, the council listed and ranked buildings in four categories:
- height of structural or architectural top;
- height of highest floor;
- height to the top of roof (removed as category in November 2009);
- height to top of any part of the building.
