Top 10 tallest buildings in the world

Architectural top and antenna height

Architectural height includes an integral spire but excludes an antenna or other removable technical equipment. The distinction is why a photograph of the highest visible point is not always enough to reproduce the official order. Measuring to the roof, to the highest occupied floor or to the absolute tip would answer different questions. CTBUH documents the conventions so a decorative or structural architectural feature is treated consistently across buildings with very different forms.

Completion and eligibility

A proposed height is not a measured completed height. Keeping buildings under construction outside the candidate pool prevents a projected design from displacing an existing building before it meets the record’s requirements. The archive also uses a 2025 cutoff, so later completions should not silently alter the saved game. Burj Khalifa, Merdeka 118 and Shanghai Tower provide recognizable anchors, but the rule must be applied to every entry rather than only the most famous few.

Reading closely spaced positions

Several towers in the answer set have similar architectural heights. A display order among equal measurements does not imply an additional metre of height. The Guangzhou and Tianjin CTF names also need their city qualifier, because they refer to distinct buildings. Height alone says little about total floor space, number of floors or how high visitors can go. A slimmer tower can outrank a building with substantially more usable area. When checking another table, first match the architectural-height convention and completed-building status, then compare the relevant historical cutoff before treating a new building as an archive correction.
