2,090,000

seats

How to estimate it

Fermi’s official “Napkin math”

The NFL has 32 teams, but the Giants and Jets share a stadium and so do the Rams and Chargers. That leaves 30 buildings. How big is one? They are enormous, call it 70,000 seats.

NFL stadiums
30
Seats each
× 70,000
30 × 70,000
≈ 2,100,000

Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.

Source calculation & reference
NFL stadiums (32 teams, but two venues host two teams each)
30
Published capacities, from 60,108 (Highmark) to 82,500 (MetLife)
sum = 2,086,438
≈
2,090,000
