What is the total weight of the Eiffel Tower?

The Eiffel Tower weighs approximately 10,100 tonnes in total. That figure includes not only its wrought-iron structure but also its elevators, shops, equipment, and antennas.

The tower's puddled iron alone accounts for about 7,300 tonnes. The difference comes from the machinery and facilities added to make the monument usable as a public attraction and communications structure. Despite its enormous mass, the lattice design uses material efficiently rather than forming a solid block.

The tower's weight is sometimes confused with the weight of its ironwork alone. That explains why figures around 7,300 tonnes also appear in books and travel descriptions. Another interesting detail is that the metal expands and contracts with temperature: the top can shift by up to roughly 18 centimetres as sunlight heats one side. The total-weight estimate therefore refers to the completed monument and its installed components, not just its original framework.
