How the World's Tallest Buildings Board screensaver works
The saver displays a real, curated ranking of the world's tallest completed buildings by real official height.
Each building shows its real height, real city and real year completed.
The board refreshes periodically as new real supertall buildings top out.
No live feed is required — figures are a real, curated periodic snapshot.
How a building's height is officially counted
The Council on Tall Buildings and Urban Habitat (CTBUH), based in Chicago, is widely regarded as the authority on the official height of tall buildings and publishes the criteria used for the standard rankings. Its main measure is height to architectural top, which counts spires that are part of the design but excludes antennas, signage, flagpoles and other equipment, because those can be added, removed or changed over time. The organisation announced a rebrand as the Council on Vertical Urbanism in October 2025, so you may see either name.
The criteria define two other measures: height to highest occupied floor, and height to tip, which goes to the very top of the structure whatever it is. A tower with a tall spire can rank above a rival on one measure and below it on another, which is why arguments arise. A structure only counts as a building if at least half of its height is occupiable. Telecommunications and observation towers that fail that test are left out of the tallest-building lists.
All three measures start from the same level: the finished floor at the threshold of the lowest significant, open-air, pedestrian entrance. A building is counted as complete when it is topped out structurally and architecturally, fully clad, and open for business or at least partially occupiable. A board like this one shows a snapshot that changes as new towers are finished.
A worked example
A newly completed supertall tower enters the board at its real ranked position, exactly matching its official published height.

Frequently asked questions
- Is this real height data?
- Yes — real official figures from the Council on Tall Buildings and Urban Habitat.
- Is a key needed?
- No — figures are a curated real periodic snapshot.
- Does it include buildings under construction?
- No — only real completed, occupied buildings are ranked.
- Is it free?
- Yes — free, no download, in your browser.
- What is height to architectural top?
- The measure used for the main ranking. It includes spires that are part of the design but not antennas, signage, flagpoles or other equipment.
- Why are broadcast towers not on the list?
- They are classed as towers, not buildings. A structure counts as a building only if at least 50 percent of its height is occupiable.
- Where is the height measured from?
- From the finished floor at the lowest significant, open-air, pedestrian entrance, so published heights can differ between sources that use another starting point.
