What is a Skyscraper?

The Chicago skyline is defined by its skyscrapers, but what is a skyscraper exactly? Skyscrapers are defined as, “a very tall building of many stories,” though in practice, an expanded definition has been accepted.

How Tall is a Skyscraper?

So, how tall is a skyscraper? The definition of a skyscraper has changed throughout history. In the 1880s, the term was first coined in Chicago to describe the Home Insurance Building. The Home Insurance Building was only 10-stories high, but at the time the building and its steel-framed construction was considered a true innovation. Buildings that ranged between 10 and 20 floors continued to be labeled as “skyscrapers” for years to come. As advances were made in construction, the qualifications to be considered a skyscraper grew to 150-meter (492-foot) minimum. 

What is Considered a Skyscraper? 

While the height is the most apparent qualification for a skyscraper, there is more to a skyscraper than its impressive stature. To be considered a true skyscraper, the building must be self-supporting and contain at least 50% habitable floor space. The precludes dedicated observation towers and other tall structures from qualifying as skyscrapers. 

How Many Skyscrapers are in Chicago?

Compared to other cities with skyscrapers, Chicago is ranked as the eighth-tallest city in the world! While Chicago is known for its architecture and sky-piercing buildings, not all meet the current criteria for a skyscraper. Out of the list of tall buildings found in the Windy City, almost 130 are considered actual skyscrapers.
