List of tallest structures

The tallest structure in the world is the Burj Khalifa, a skyscraper that reaches 828 meters (2,717 feet) into the sky. Structures like this amaze us because of how high they climb above the Earth. This list includes many different kinds of tall objects, such as skyscrapers like the Burj Khalifa and the Willis Tower, tall towers like the CN Tower, and even special structures used for oil and electricity.

Being able to build such incredibly tall structures shows how clever engineers and architects can be. These buildings and towers serve many purposes, from holding offices and homes to sending messages across the world. The list organizes these amazing structures by how high they are, letting us see which ones stand above all others.

Terminology

The way we describe and list tall structures follows rules set by the Council on Tall Buildings and Urban Habitat. We make differences between guyed masts, which use wires for support, and towers, which stand on their own without any extra support. We also differentiate buildings from towers: buildings must have at least half of their space that people can actually use and live or work in, while towers are self-supporting but may not have as much usable space.

Lists by height

This list shows structures taller than 350 meters (1,148 feet). Some special structures shorter than 350 meters are also included if they hold important records. The heights listed are the highest points of each structure, which might be different from the heights listed for skyscrapers alone.

Tension-leg platforms are not included in this list.

On hold/cancelled or proposed

These are structures that are currently on hold, have been cancelled, or are still just ideas that might be built in the future. They include skyscrapers, towers, and other tall constructions that haven't been completed yet or won't be built at all.
