Olympus Mons is about 2½ Everest elevations tall.
NASA gives the Martian volcano a height of about 21.9 km for this reference.
Approximate calculated comparison
Why this is interesting
How this measurement works
Planetary heights do not have one universally agreed base or reference surface the way sea-level elevations do on Earth, and different NASA/JPL materials present Olympus Mons differently depending on the basis used. This comparison is bound to the cited NASA reference basis of about 21.9 km — it is not a claim that 21.9 km is the single exact physical height of the volcano.
See the math

- ≈21.9 kmSource value
- Mount Everest summit elevation

How certain is this?
Calculated comparison, tied to one cited planetary measurement basis — other defensible definitions exist.
Tied to the cited NASA reference basis of about 21.9 km. That is not the only defensible definition of Olympus Mons' height.
