How tall is the Burj Khalifa?

The story behind the answer

2,722 ft is the Burj Khalifa’s height to tip—the very highest point of the spire. Its official architectural height is 828 meters, about 2,717 ft, which is why you sometimes see that nearby figure. Both are correct in different measurement categories, but 2,722 ft marks the absolute top.

Opened in 2010 in Dubai, the Burj Khalifa has 163 floors and uses a buttressed-core design (by SOM/Adrian Smith) to resist powerful desert winds. Its Y-shaped footprint was inspired by the Hymenocallis flower, helping stability and views. Memory tip: think “two-7-two-2”—two 2s bookend 72—like two dunes flanking the world’s tallest spike.
