The tallest buildings in the world are ranked by architectural height, most commonly using the Council on Tall Buildings and Urban Habitat (CTBUH) standard. As of 2026, Burj Khalifa in Dubai is the tallest completed building in the world, followed by Merdeka 118 in Kuala Lumpur and Shanghai Tower in Shanghai. The CTBUH defines a tall building as one with 14 or more stories and a height above 50 metres.

Ranking method

The standard reference for global tall-building rankings is the CTBUH, which classifies tall buildings by architectural height. Architectural height counts the building’s structure but not antennas or other non-building masts. The CTBUH also defines a tall building as one with at least 14 stories and a height above 50 metres.

Current top rankings

The tallest completed building is Burj Khalifa in Dubai, followed by Merdeka 118 in Kuala Lumpur and Shanghai Tower in Shanghai. Other buildings commonly listed near the top include the Makkah Royal Clock Tower, Ping An Finance Center, and Lotte World Tower.

Record-holding buildings

Burj Khalifa is notable not only for its height but also for its 163 occupied floors. It has remained the tallest completed building since 2010 and is frequently cited as a landmark example of modern supertall construction.

Ongoing and proposed projects

The title of tallest building may change if projects under construction are completed. Jeddah Tower has been widely reported as a planned supertall tower intended to exceed 1,000 metres.

Key facts

  • Burj Khalifa has been the world's tallest completed building since its completion in 2010.
