. The roof height of the building, excluding the spire, is 1,368 feet (417 meters), which matches the height of the original North Tower of the World Trade Center

. The building has 104 floors in total

. Thus:

• Height to roof: 1,368 feet (417 m)
• Height including spire: 1,776 feet (541 m)

This makes One World Trade Center the tallest building in the United States and the Western Hemisphere
