List of tallest buildings in Dubai
Dubai, the largest city in the United Arab Emirates, is home to many modern high-rises, 88 of which stand taller than . The tallest building in Dubai is the Burj Khalifa, which rises and contains 161 floors. The tower has stood as both the tallest building in the world and the tallest man-made structure of any kind in the world since its completion in January 2010. The second-tallest building in Dubai is the Marina 101, which also stands as the world's tallest residential skyscraper. The skyscrapers of Dubai are, for the most part, clustered in three different locations. The land along Sheikh Zayed Road was the first to develop, followed by the Dubai Marina neighborhood and the Business Bay district.
Vanity height
The controversy began when the Petronas Towers were named as the world's tallest buildings in 1998, despite having a roof 63.4 m (208 ft) lower than that of the Willis Tower. The current 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 defined as 244 meters, or 29% of the building's total height. The likely next tallest building, Jeddah Tower (designed by the same architect), will be over 1,000 meters tall but its highest floor is 630m above ground. The top 370m (equivalent to an 85-story building) or 37% of the building's total height is unusable. When vanity height is excluded, the height progression of the world's tallest buildings looks much more modest in comparison.
