How to estimate it

Fermi’s official “Napkin math”

Taylor performed in basically every major city, often multiple nights. Each night was a sold out stadium. If she performed two nights in 60 cities, that's 120 shows. The stadium near me seats 65,000. Multiply them and you get eight million-ish.

Cities
≈ 60
Nights per city
× 2
Fans per show
× 65,000
60 × 2 × 65,000
≈ 7,800,000

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

Average per show
