Measurements, assumptions & sources +
Hoover Dam
A rounded 221.4 m structural-height anchor; water level changes.
Defined examples — our methodology
The marked height is calibrated. Unmeasured illustration details are representative.
Burj Khalifa
Architectural height to the top of the spire, 828 m. It is useful to compare consistently stated heights, since roof, antenna and occupied-floor heights differ.
Guinness World Records — Burj Khalifa

- Relative size
- Burj Khalifa is larger on this measurement by a factor of about 3.74. Burj Khalifa's selected measurement is approximately 274% greater than Hoover Dam's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Hoover Dam is labelled rounded landmark reference; treat the displayed value as a comparison anchor rather than false precision.
