Tallesteder

Tallesteder is a wiki-style online encyclopedia that catalogs the world’s highest places and structures, combining natural elevations with man-made heights. The project aims to present verifiable measurements and concise descriptions of sites that rank among the tallest by widely used criteria.

The name tallesteder is a portmanteau drawn from Scandinavian-rooted terms for 'place' (sted/steder) and the English adjective 'tallest,' and several language communities use related compound forms to describe the same concept. The article uses standard naming for each entry, with cross-links to related lists such as mountains, towers, and waterfalls.

Measurements follow established baselines: elevations above sea level for mountains and hills; height to the tip for buildings and towers; total drop for waterfalls. Where sources differ, the entry notes the measurement used and provides citations to authoritative references. Units are given in meters and feet.

Notable entries include Mount Everest at 8,848 meters above sea level; Burj Khalifa at 828 meters tall; Angel Falls with a single-drop height of 979 meters; Mauna Kea, about 10,210 meters from its base on the ocean floor, though 4,207 meters above sea level. The list is not exhaustive and is subject to updates as new measurements become available.

Tallesteder is maintained by a community of volunteer editors who follow a neutral-point-of-view policy, require reliable sources, and encourage citations. The project may include disputed entries when credible sources provide differing measurements, and it maintains discussion pages for consensus building.
