Vanity height is defined by the Council on Tall Buildings and Urban Habitat (CTBUH) as the height difference between a skyscraper's pinnacle and the highest usable floor (usually observatory, office, restaurant, retail or hotel/residential). [1] Because the CTBUH ranks the world's tallest buildings by height to pinnacle, a number of buildings appear higher in the rankings than they otherwise would due to extremely long spires. [2]
The controversy began when the Petronas Towers were named the world's tallest buildings in 1998, despite having a roof 63.4 m (208 ft) lower than that of the Willis Tower. The world's tallest building, Burj Khalifa, is officially 828 meters tall, but its highest usable floor is 585m above ground. Therefore, its vanity height is 244 meters or 29% of the building's total height. Without this vanity height, the Burj Khalifa would still be the tallest building in the world, but only by 2 meters. [1] [3]
The next potentially tallest building, the Jeddah Tower, could be over 1,000 meters tall, but its highest floor is planned to be 630m above ground. The top 370m (equivalent to an 85-story building), or 37% of the building's total height, will be unusable. When vanity height is excluded, the height progression of the world's tallest buildings looks much more modest. [4] [5]
The CTBUH requires a structure's vanity height to be under 50% to be defined as a "building." Otherwise, it is considered a communications tower and ineligible for the rankings. [1]
A skyscraper is a tall, continuously habitable building having multiple floors. Modern sources currently define skyscrapers as being at least 100 meters (330 ft) or 150 meters (490 ft) in height, though there is no universally accepted definition, other than being very tall high-rise buildings. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s. Skyscrapers may host offices, hotels, residential spaces, and retail spaces.
The Council on Tall Buildings and Urban Habitat (CTBUH) is an international body in the field of tall buildings, including skyscrapers, and sustainable urban design. A non-profit organization based at the Monroe Building in Chicago, Illinois, United States, the CTBUH announces the title of "The World's Tallest Building" and is widely considered to be an authority on the official height of tall buildings. Its stated mission is to study and report "on all aspects of the planning, design, and construction of tall buildings."
Taipei 101, formerly known as the Taipei World Financial Center, is a skyscraper in the capital Taipei, Taiwan. It is owned by Taipei Financial Center Corporation. The building was officially classified as the world's tallest from its opening on 31 December 2004. However, the Burj Khalifa surpassed Taipei 101 in 2009. Upon completion, it became the world's first skyscraper to exceed a height of half a kilometer. As of 2023, Taipei 101 is the tallest building in Taiwan and the eleventh tallest building in the world.
The Burj Khalifa is a skyscraper in Dubai, United Arab Emirates. It is the world's tallest building. With a total height of 829.8 m and a roof height of 828 m (2,717 ft), the Burj Khalifa has been the tallest structure and building in the world since its topping out in 2009, supplanting Taipei 101, the previous holder of that status.

Shanghai Tower is a 128-story, 632-meter-tall (2,073 ft) megatall skyscraper in Lujiazui, Pudong, Shanghai. It is the tallest building in China and the world's third-tallest building by height to architectural top. It is the tallest and largest LEED Platinum certified building in the world since 2015. It shares the record of having the world's highest observation deck within a building or structure at 562 m. It had the world's second-fastest elevators at a top speed of 20.5 meters per second until 2017, when it was surpassed by the Guangzhou CTF Finance Center, with its top speed of 21 meters per second. Designed by international design firm Gensler and owned by the Shanghai Municipal Government, it is the tallest of the world's first triple-adjacent supertall buildings in Pudong, the other two being the Jin Mao Tower and the Shanghai World Financial Center. Its tiered construction, designed for high energy efficiency, provides nine separate zones divided between office, retail and leisure use.
Jeddah Tower, previously known as Kingdom Tower, is a skyscraper construction project in Jeddah, Saudi Arabia. It is planned to be the first 1 km (3,281 ft) tall building and would be the world's tallest building or structure upon completion, standing 180 m (591 ft) taller than the Burj Khalifa. Located in the north side of Jeddah, it is the centerpiece of the Jeddah Economic City project. After almost five years of inactivity, development work on the project resumed in 2023.
The tallest building in the world, as of 2023, is the Burj Khalifa in Dubai, United Arab Emirates.
