Within 5 km of the summit
3,842 m is the height IGN gives. The map and the figures here read the Copernicus 30 m model on 2026-11-14; the map opens on its highest cell at the summit, 3,695 m.

AI AgentFrequently asked questions
What is the elevation of Aiguille du Midi in feet and metres?
Aiguille du Midi is 3,842 m, or 12,605 ft, above sea level (IGN). The Copernicus 30 m elevation model reads 3,695 m at its highest cell there.
How is the elevation of Aiguille du Midi measured?
The official height comes from IGN. The map on this page reads the Copernicus DEM instead, a 30 m elevation model made from satellite radar between 2011 and 2015. It gives 3,695 m at the summit: each cell averages about 30 m of surface, so a sharp top reads lower than it is.
How thin is the air at the top of Aiguille du Midi?
At 3,842 m (12,605 ft), air pressure is about 62 % of its sea-level value in the standard atmosphere, so each breath brings in about that share of the oxygen. Altitude sickness becomes common above 2,500 m (8,200 ft) for people who come up from low ground in a day.
How far below the summit of Aiguille du Midi is the ground around it?
Within 5 km of the summit, the lowest ground is at 1,010 m (3,312 ft), at 45.90432, 6.83645: 2,833 m below the top. Half of the ground in that circle lies above 2,756 m.
