How high can skyscrapers be built?

Skyscrapers can be as high as 2700 meters.

After reaching a certain altitude, the body adapts to the changes such as air pressure difference, low oxygen content and dry air caused by altitude.

The natural physiological reaction caused by this change, when the altitude generally reaches about 2700 meters, will appear altitude sickness.

The environment above 2700 meters is not suitable for human survival.

Although skyscrapers can be built higher technically, science and technology serve human beings. If the environment exceeds 2700 meters, it is not suitable for human survival.

Skyscraper, also known as super high-rise building, is a very high multi-storey building.

Originally a building with 10 to 20 floors, now it usually refers to a high-rise building with more than 40 to 50 floors.

The definition of super high-rise building in France is more than 60 meters.

In the United States, buildings over 152 meters (500 feet) are generally considered as skyscrapers.
