This list of skyscrapers by floor area includes the largest skyscrapers in the world, measured in square meters (m 2) and square feet (sq ft). To qualify as a skyscraper, a structure must be self-supporting, without relying on tension cables or external supports for stability, and must reach a minimum height of 150 meters (492 feet).
Vanity height first appeared in New York City skyscrapers as early as the 1920s and 1930s but supertall buildings have relied on such uninhabitable extensions for on average 30% of their height, raising potential definitional and sustainability issues.
For skyscrapers, though, as the size of the structure increases, so does the size of the supporting wall. Large structures such as castles and cathedrals inherently addressed these issues due to a large wall being advantageous (castles), or able to be designed around (cathedrals). Since skyscrapers seek to maximize the floor-space by ...
The history of skyscrapers in New York City began with the construction of the Equitable Life, Western Union, and Tribune buildings in the early 1870s. These relatively short early skyscrapers, sometimes referred to as "preskyscrapers" or "protoskyscrapers", included features such as a steel frame and elevators—then-new innovations that were used in the city's later skyscrapers.
Night view of the skyline of Hong Kong, which has over 500 skyscrapers. The list of cities with most skyscrapers ranks cities around the world by their number of skyscrapers. A skyscraper is defined as a continuously habitable high-rise building that has over 40 floors [1] and is taller than approximately 150 m (492 ft). [2]
111 West 57th Street in Midtown Manhattan is the world's most slender skyscraper. In architecture, the slenderness ratio, or simply slenderness, is an aspect ratio, the quotient between the height and the width of a building. In structural engineering, slenderness is used to calculate the propensity of a column to buckle.
The second largest skyscraper by floor area in the world, the second tallest building in China, the fourth tallest building in Asia and the fourth tallest building in the world, with the height of 599.1 m (1,966 ft).

[22] [5] That was soon followed by Collins House, a 195-metre (640 ft) skyscraper that has the width of its base at 11.5 metres (38 ft). It slenderness ratio of 16.5:1 was the fourth most slender tower in the world at the time of completion.
