Answer & explanation
The official answer, with Fermi’s reasoning step by step.
Answer & explanation
Official answer
24,000
visitors
How to estimate it
Fermi’s official “Napkin math”
The Louvre is the most-visited museum on Earth, somewhere around 9 million people a year. Spread that across all 365 days.
- Louvre visitors a year
- ~9,000,000
- ÷ 365 days
- ≈ 25,000
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Annual visitors (2024)
- ~8.7 million
- Days open per year
- ~310
- 8.7 M ÷ 310
- ≈ 28,000 on open days
- Averaged across all 365 days
- ≈ 24,000
