How Many Double-Decker Buses Equal the Height of Mount Everest?

Back-of-the-Envelope Calculation

Mount Everest elevation: 8,848.86 m (29,031.7 ft) — 2020 China/Nepal survey

Standard double-decker bus height: ~4.0–4.4 m (13–14.5 ft) — e.g., Alexander Dennis Enviro400: 4.3 m

Calculation

Using 4.3 m average:

8,848.86 m ÷ 4.3 m ≈ 2,058 buses

Using 4.0 m: 2,212 buses (the figure commonly cited)

Visualizing the Stack

• End-to-end: 2,058 × 10.5 m (bus length) = 21.6 km long line
• Weight: 2,058 × 12,000 kg = 24,700 metric tons
• Passenger capacity: 2,058 × 80 = 164,640 people

Caveats

• Buses aren't designed for vertical stacking (crush strength, stability)
• Everest's snow/ice cap varies seasonally (~2–5 m)
• Mauna Kea (base-to-summit) is taller (10,210 m) → ~2,374 buses

Fun Comparison

• Eiffel Tower (330 m): ~77 buses
• Burj Khalifa (828 m): ~193 buses
• Commercial airliner cruise altitude (10,668 m): ~2,480 buses
• Kármán line (space, 100 km): ~23,256 buses
