An average skyscraper is usually a multistory building with an architectural height of at least 100 meters. The average height seems to be increasing with time. The Council on Tall Buildings and Urban Habitat has reported that 600 meters seem to be the new 300 meters, with the increasing demand of taller buildings.
The term "Supertall" is used for the buildings that are taller than 300 meters or 984 feet, while skyscrapers with more than 600 meters of height are referred to as "Megatall." All skyscrapers include a steel framework for supporting the curtain walls. Modern buildings often feature a tubular structure and this hollow cylindrical design is able to resist lateral loads like seismic activity or wind.
