Burj Khalifa

Bringing Burj Khalifa to life required a combination of visionary ideals and solid science. In the process, the project amassed an awe-inspiring number of facts, figures, and statistics.
World Records
At over 828 metres (2,716.5 feet) and more than 160 stories, Burj Khalifa holds the following records:

Tallest building in the world

Tallest free-standing structure in the world

Highest number of stories in the world

Highest occupied floor in the world

Highest outdoor observation deck in the world

Elevator with the longest travel distance in the world

Tallest service elevator in the world

Tallest of the Supertall
Not only is Burj Khalifa the world’s tallest building, it has also broken two other impressive records: tallest structure, previously held by the KVLY-TV mast in Blanchard, North Dakota, and tallest free-standing structure, previously held by Toronto’s CN Tower. The Chicago-based Council on Tall Buildings and Urban Habitat (CTBUH) has established 3 criteria to determine what makes a tall building tall. Burj Khalifa wins by far in all three categories.

Height to architectural top
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building. This includes spires, but does not include antennae, signage, flagpoles or other functional-technical equipment. This measurement is the most widely used and is used to define the Council on Tall Buildings and Urban Habitat rankings of the Tallest Buildings in the World.

Highest occupied floor
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest continually occupied floor within the building. Maintenance areas are not included.

Height to tip
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element. This includes antennae, flagpoles, signage and other functional-technical equipment.
