Why the Race to Build Higher Never Really Stops

The title of world's tallest building has changed hands many times throughout history. Cities and countries often see a record-setting skyscraper as a symbolic statement of economic power and engineering capability, which is part of why the competition to build higher keeps going even today.

How Height Is Actually Measured

A building's official height is generally measured to the top of its architectural spire, but antennas and flagpoles that are not considered part of the structure are typically excluded — which is why rankings can shift depending on exactly what is being counted.

Frequently Asked Questions

How is a building's height measured?

Height is generally measured to the top of the roof or architectural spire. Elements like antennas or flagpoles that are not considered structural are often excluded from official height records, which is why rankings can vary depending on the measurement standard used.

Will anything ever surpass the Burj Khalifa?

Several proposed projects, including Saudi Arabia's Jeddah Tower, have aimed to exceed the Burj Khalifa's height. Whether and when such projects actually get finished depends heavily on each country's economic conditions and construction timelines.
