List of tallest buildings
This is a list of the tallest buildings. Tall buildings, such as skyscrapers, are intended here as enclosed structures with continuously occupiable floors and a height of at least. Such definition excludes non-building structures, such as towers.
History
Historically, the world's tallest man-made structure was the Great Pyramid of Giza in Egypt, which held the position for over 3,800 years until the construction of Lincoln Cathedral in 1311. The Strasbourg Cathedral in France, completed in 1439, was the world's tallest building until 1874.The first building considered to be a skyscraper was the Home Insurance Building, built in Chicago in 1885. The United States would remain the location of the world's tallest building throughout the 20th century until 1998, when the Petronas Towers were completed. Since then, two other buildings have gained the title: Taipei 101 in 2004 and Burj Khalifa in 2009. Since the beginning of the 21st century, the Middle East, China, and Southeast Asia have experienced booms in skyscraper construction.
Ranking criteria and alternatives
The international non-profit organization Council on Tall Buildings and Urban Habitat 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. However, the CTBUH only recognizes buildings that are complete, and some buildings included within the lists in this article are not considered finished 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 to structural or architectural top;
- height to highest occupied floor;
- height to top of roof ; and
- height to top of any part of the building.
Spires are considered integral parts of the architectural design of buildings, changes to which would substantially change the appearance and design of the building, whereas antennas may be added or removed without such consequences. The Petronas Towers, with their spires, are thus ranked higher than the Willis Tower with its antennas, despite the Petronas Towers' lower roofs and lower highest point.
Until 1996, the world's tallest building was defined by the height to the top of the tallest architectural element, including spires but not antennae. In 1930, this definitional argument led to a rivalry between the Bank of Manhattan Building and the Chrysler Building. The Bank of Manhattan Building employed only a short spire, was tall, and had a much higher top occupied floor. In contrast, the Chrysler Building employed a very large spire secretly assembled inside the building to claim the title of world's tallest building with a total height of, although it had a lower top occupied floor and a shorter height when both buildings' spires were excluded.
Upset by Chrysler's victory, Shreve & Lamb, the consulting architects of the Bank of Manhattan Building, wrote a newspaper article claiming that their building was actually the tallest, since it contained the world's highest usable floor, at. They pointed out that the observation deck in the Bank of Manhattan Building was nearly above the top floor in the Chrysler Building, whose surpassing spire was strictly ornamental and inaccessible.
The Burj Khalifa currently tops the list regardless of which criterion is applied, though at a much lower margin when measured to highest occupied floor.
Tallest buildings in the world
, this list includes all 97 buildings that reach a height of or more, as assessed by their highest architectural feature. The building is considered as architecturally topped out when it is under construction, structurally topped out, fully clad, and the highest finished architectural elements are in place.Of these buildings, almost half are in China. Six of the last seven buildings to have held the record as 'tallest building' are still found in the list, with the exception being the North Tower of the original New York World Trade Center at after its destruction in the September 11 attacks of 2001. Had the Twin Towers never been destroyed and One World Trade Center never built, the WTC towers would rank 39 and 40 on the list today.

Alternative measurements
Height to pinnacle (highest point)
This measurement disregards distinctions between architectural and non-architectural extensions, and simply measures to the highest point, irrespective of material or function of the highest element.This measurement is useful for air traffic obstacle determinations, and is also a wholly objective measure. However, this measurement includes extensions that are easily added, removed, and modified from a building and are independent of the overall structure.
This measurement only recently came into use, when the Petronas Towers passed the Sears Tower in height. The former was considered taller because its spires were considered architectural, while the latter's antennae were not. This led to the split of definitions, with the Sears Tower claiming the lead in this and the height-to-roof categories, and with the Petronas claiming the lead in the architectural height category.
If the original World Trade Center towers were still standing, the North and South Towers would fall between numbers 11 and 37 on the current list.

Height to occupied floor
This height is measured to the highest occupiable floor within the building.Height to roof
This list of tallest buildings by height to roof ranks completed skyscrapers by height to roof which reach a height of 300 metres or more. Only buildings with continuously occupiable floors are included, thus non-building structures, including towers, are not included. Some assessments of the tallest building use 'height to roof' to determine tallest building, as 'architectural feature' is regarded as a subjective and an imprecise comparative measure. However, in November 2009, the CTBUH stopped using the roof height as the metric for tall buildings because modern tall buildings rarely have a part of the building that can categorically be deemed the roof.| Rank | Building | City | Country | Height | Height | Floors | Built | Reference | ||||||||||||||||
