The Empire State Building's height is a moving target

In short: While many know its iconic silhouette, few realize that the building's official height has shifted significantly over time. From its initial 1931 completion to various structural additions and replacements, the skyscraper’s stature reflects decades of evolving technology and changing architectural priorities in New York City.

Completed in 1931, the Empire State Building originally stood as a marvel of Modernist Art Deco design. At its inauguration, it seized the title of world's tallest building from the Chrysler Building, which had claimed the crown in 1929. The structure’s primary height is cited as 1,250 feet (381 meters), a measurement that excludes the television antenna mast but includes its iconic spire. The skyscraper is situated in Midtown Manhattan on Fifth Avenue at 34th Street. Its design features a steel frame and spans 102 stories. The spire was originally planned to function as a mooring station for airships.

The building's vertical reach has fluctuated due to technological upgrades. In 1950, a 222-foot (68-meter) antenna was added, pushing the total height to 1,472 feet (449 meters). However, this figure was later reduced to 1,454 feet (443 meters) in 1985 when the antenna was replaced. Despite these changes, it maintained its status as the world's tallest building for approximately 40 years until 1971. By the time of this reduction in 1985, One World Trade Center had already become the tallest structure on Earth. That landmark officially opened its doors in 1972.

The project was born from a unique partnership between John J. Raskob and Al Smith. Though they came from different worlds—Raskob a business mogul and Smith a former Democratic governor—they were united by their shared backgrounds as children of struggling immigrant families. Their collaboration on the building followed Smith's 1928 presidential run, a campaign that highlighted the era's complex social dynamics regarding economic prosperity and religious identity. Raskob previously served as chairman for the Democratic National Committee. He also managed Smith's campaign during the 1928 election cycle. This period of history showed a public wary of electing a Roman Catholic to the presidency.
