Zoom out from an average adult to One World Trade Center

One World Trade Center is too big to show next to an average adult in one picture, so here it is in 3 steps. Each step is drawn to its own scale and zooms out from the step before.

  1. Step 1 of 3 Human → Megalodon

    A megalodon is about 8.6–15 times as long as an average adult is tall.

    Step 1: Human and Megalodon at the same scale.

  2. Step 2 of 3 Megalodon → Great Pyramid of Giza

    The Great Pyramid of Giza is about 5.6–9.1 times as tall as a megalodon is long.

  3. Step 3 of 3 Great Pyramid of Giza → One World Trade Center

    One World Trade Center is about 4 times as tall as the Great Pyramid of Giza.

About One World Trade Center

One World Trade Center is the main tower of the rebuilt World Trade Center in Lower Manhattan, New York City, completed in 2014. Its architectural height of 1,776 ft (541.3 m), which counts the spire, makes it the tallest building in the United States on the Skyscraper Center's list. The very top of the building reaches 546.2 m (1,792 ft).

  • One World Trade Center has 94 floors above ground and 5 below ground. [1]
  • Construction started in 2006 and the tower was completed in 2014. [1]
  • The Skyscraper Center ranks it the tallest building in North America, the United States and New York City, and the seventh-tallest in the world (September 2026). [1]
  • It was designed by Skidmore, Owings & Merrill; the current owners are the Port Authority of New York and New Jersey and The Durst Organization. [1]

How many fit?

  • ≈ 320 × Human · height lined up end to end match the One World Trade Center · height (architectural)
  • ≈ 4.4 × Starship · full-stack height lined up end to end match the One World Trade Center · height (architectural)

Counts divide one sourced figure by another. "End to end" uses each object's main measurement; weight and volume rows appear only when both figures are sourced.

How it compares

  • 320× One World Trade Center is about 320 times as tall as an average adult. See side by side
  • 4.4× One World Trade Center is about 4.4 times as tall as SpaceX's Starship. See side by side
  • 4× One World Trade Center is about 4 times as tall as the Great Pyramid of Giza. See side by side
  • 1.6× One World Trade Center is about 1.6 times as tall as an aircraft carrier is long. See side by side
  • 1.2× One World Trade Center is about 1.2 times as tall as the Empire State Building. See side by side
  • 1/1.5 The Burj Khalifa is about 1.5 times as tall as One World Trade Center. See side by side

Factors compare the height (architectural) of One World Trade Center with each object’s own main measurement (height for a human). Where a size varies, the factor is given as a range.

Notes on these figures

  • The Skyscraper Center database now carries the Council on Vertical Urbanism (CVU) name; its height categories are the CTBUH ones (architectural top includes spires but not antennas).
  • The 1,776 ft architectural height includes the spire; the 546.2 m to-tip figure is the highest point of the building.
  • World rankings change as new towers are completed; the ranks quoted are as shown on the Skyscraper Center in September 2026.
