A close-up shot capturing the intricate details of the Empire State Building's foundation, showcasing its massive strength and leaving viewers pondering its weight.

How Much Does The Empire State Building Weigh?

The Empire State Building is one of the most iconic skyscrapers in the world. Towering over Midtown Manhattan at 1,454 feet tall, this Art Deco wonder has been fascinating people since it opened in 1931. But have you ever wondered just how heavy a building that size is?

Read on to find out the staggering weight of this New York City landmark.

If you’re short on time, here’s a quick answer to your question: the Empire State Building weighs around 365,000 tons.

Construction Materials

Steel framework

The Empire State Building has a steel framework consisting of 60,000 tons of steel. The steel columns, beams and trusses were fabricated by the American Bridge Company in their Ambridge, Pennsylvania plant and shipped to the construction site in New York.

Erecting the steel framework was a feat of engineering, requiring precision planning and execution. At certain points during construction, crews were adding 4 and a half floors per week, an astonishing rate at the time.

Concrete floors and walls

In addition to its steel framework, the Empire State Building contains 10 million bricks and 730 tons of aluminum and stainless steel. The building has 6,514 windows. The concrete floors and walls were constructed using the most advanced techniques of the era, allowing them to be built rapidly while maintaining strength and stability.

The concrete work enabled the building to rise at its record pace.

Granite and limestone facade

The exterior facade of the Empire State Building is perhaps its most iconic feature. Covering the steel and concrete structure is granite and limestone paneling sourced from quarries in Massachusetts and Indiana. Over 10 million bricks were used to build the facade.

The granite and limestone panels give the building its recognizable sleek, Art Deco styling. The facade was groundbreaking in its technological innovation. At the time, installing pre-cut stone paneling on a skyscraper had never been attempted.

Building Dimensions


The Empire State Building towers over New York City at 1,454 feet (443.2 meters) tall, measured from the sidewalk to the tip of its lightning rod. This makes it the 7th tallest building in the United States, though it was the world’s tallest skyscraper for over 40 years after its completion in 1931.

The building has 102 floors of rentable space, stacked vertically atop its base. To reach the observatory deck on the 86th floor, visitors ride elevator cars moving at 1,000 feet per minute – about 10.5 mph.

The building sways a maximum of only 1 foot at the top level, thanks to its sturdy steel frame and deep foundation.

Floor Area

Though appearing slender from afar, the Empire State Building actually covers 2.768 million square feet inside – about 63.1 acres. This is over twice the floor area of the world’s current tallest building, Dubai’s 2,716.5-foot-tall Burj Khalifa.

If all the Empire State Building’s floors were arranged horizontally side-by-side, they would cover the area of about 35 football fields. Rentable office and retail space occupies about 2.158 million square feet, while the remainder is for mechanical equipment and observatory decks.

Calculating the Weight

Steel framework weight

The Empire State Building has an intricate steel framework that forms the core structure of the iconic 102-story skyscraper. According to official statistics, the building contains 60,000 tons of steel.

The vast steel skeleton, comprising framework columns and trusses, was engineered by American Bridge Company and fabricated by their subsidiary, McClintic-Marshall. This massive amount of steel provides the strength and stability for the tall building.

Concrete weight

In addition to its steel framework, the Empire State Building contains 10 million bricks and 730 tons of aluminum and stainless steel. But perhaps the most interesting fact is the amount of concrete used – a staggering 43,600 cubic yards (33,450 cubic meters).

This is equivalent to a solid cube of concrete measuring over 200 feet (60 meters) on each side. The extensive use of concrete in the building’s core and floors contributes significantly to its overall weight and stability.

Facade weight

The exterior facade of the Empire State Building is another source of substantial weight. Covering over 200,000 square feet (18,580 square meters), the distinctive art deco facade is composed of Indiana limestone panels and aluminum spandrels.

By estimating the volume and density of these materials, we can calculate that the facade likely weighs around 10,000 tons. The bulk of this comes from the limestone cladding which gives the building its iconic sleek appearance.

Total weight estimate

Adding up the key structural materials, the total estimated weight of the Empire State Building is approximately:

  • 60,000 tons of steel framework
  • 33,450 cubic meters of concrete weighing around 100,000 tons
  • 10,000 tons of stone and aluminum exterior facade

This gives a grand total of around 170,000 tons or 340 million pounds! That’s roughly the equivalent weight of about 34,000 elephants. This immense weight is supported by the building’s strong steel skeleton and wide concrete base.

The surprisingly heavy load gives the towering structure exceptional stability and resistance to winds and earthquakes. Next time you gaze up at this Art Deco wonder, remember the incredible feat of engineering supporting thousands of tons high in the Manhattan skyline!

Weight Compared to Other Structures

Empire State Building vs. Eiffel Tower

The Empire State Building, an Art Deco skyscraper in New York City, weighs approximately 365,000 tons. In comparison, Paris’s iconic Eiffel Tower weighs around 10,100 tons, making the Empire State Building over 36 times heavier than the Eiffel Tower.

According to the Empire State Building’s website, the building reaches a height of 1,454 feet tall with 102 stories. Constructed mainly of limestone, granite, concrete and metal, it’s no wonder this towering giant dwarfs the Eiffel Tower in weight.

Though not as tall, the volume and density of materials give it substantially more heft.

Empire State Building vs. Golden Gate Bridge

Spanning across the San Francisco Bay, the stunning Golden Gate Bridge weighs an estimated 887,000 tons according to the Golden Gate Bridge Highway and Transportation District. That’s over twice the amount of the Empire State Building’s weight!

With a 4,200 foot span length, the Golden Gate Bridge relies on enormous cables, towers and anchors to support itself across the natural landforms it traverses. This expands the total weight significantly compared to a singular high-rise structure.

Though not as vertically tall, the Golden Gate has greater horizontal reach contributing to the added mass.

Structure Weight (tons)
Empire State Building 365,000
Eiffel Tower 10,100
Golden Gate Bridge 887,000


The Empire State Building is an engineering marvel that required immense amounts of material to construct. Estimates put the total weight of this iconic skyscraper at around 365,000 tons – heavier than the Eiffel Tower! Its tremendous weight speaks to the scale and ambition of its design.

Next time you’re in New York, look up at the Empire State Building and appreciate not just its beauty, but its sheer mass.
