When comparing the world's most iconic towers, the measurement method matters critically. Here's how the three giants stack up using architectural height (including antennas)—the Council on Tall Buildings and Urban Habitat (CTBUH) standard for "height to tip."
| Structure | Total Height | Observation Deck | Location | Completed |
|---|---|---|---|---|
| Empire State Building | 1,454 ft (443.2 m) | 1,250 ft (381 m) – 86th floor | New York City, USA | 1931 |
| Willis Tower (formerly Sears Tower) | 1,451 ft (442.1 m) | 1,353 ft (412.4 m) – Skydeck, 103rd floor | Chicago, USA | 1974 |
| Eiffel Tower | 1,063 ft (324 m) | 906 ft (276.1 m) – Top platform | Paris, France | 1889 |
Each tower represents its era's engineering ambition: Eiffel's wrought-iron lattice (1889), the Empire State's Art Deco steel frame (1931), and Willis Tower's bundled-tube innovation (1974). Today, all three serve as vital telecommunications hubs, tourist magnets, and enduring symbols of their cities.
