Here's a comprehensive summary of the article about the world's tallest buildings:
The definition of a "tall building" refers to enclosed structures with continuously occupiable floors, typically exceeding 350 meters. Historically, the Great Pyramid of Giza held the record for over 3,800 years until 1311, with modern skyscrapers beginning in 1885 with Chicago's Home Insurance Building. While the United States dominated skyscraper construction throughout the 20th century, the title shifted globally in 1998 to the Petronas Towers, followed by Taipei 101 (2004), and the current record-holder, Burj Khalifa (2009), marking a boom in the Middle East and Asia.
The Council on Tall Buildings and Urban Habitat (CTBUH), founded in 1969, sets the international standards for measuring and ranking these colossal structures. A notable controversy in 1996, spurred by the Petronas Towers vs. Sears Tower (now Willis Tower) debate, led CTBUH to establish four distinct measurement categories, differentiating between architectural elements like spires and functional additions like antennas. Regardless of these complex criteria, Dubai's majestic Burj Khalifa indisputably reigns as the world's tallest building, standing at an impressive 828 meters (2,717 ft).
