Ranking Tall Buildings
See also: List of tallest buildings and structures in the worldThe CTBUH ranks the height of buildings using three different methods:
- Height to architectural top of the building. This is the main criterion under which the CTBUH ranks the height of buildings. Heights are measured from the level of the lowest, significant, open-air, pedestrian entrance to the top of the building, inclusive of spires but excluding items such as flag poles or antennae.
- To highest occupied floor: Height to the floor of the highest occupied floor of the building.
- To tip of spire/antenna: Height to the tip of spire, pinnacle, antenna, mast or flag pole.
A category measuring to the top of the roof was removed from the ranking criteria in November 2009. This is because flat-topped skyscrapers are not as common in the modern era as skyscrapers with intricate spire designs and parapet features atop their roofs, making it more difficult to define a roof on a building.
