Answer & explanation
Official answer
323
feet
How to estimate it
Fermi’s official “Napkin math”
Start with your own best throw, a paper airplane that sails across a classroom, maybe 30 feet. How much farther does a world record go? A lot farther. Call it 10 times.
- Good throw, across a classroom
- ≈ 30 ft
- Record, 10 times farther
- × 10
- 30 × 10
- ≈ 300 ft
Start with your own best throw, a paper airplane that sails across a classroom, maybe 10 meters. How much farther does a world record go? A lot farther. Call it 10 times.
- Good throw, across a classroom
- ≈ 10 m
- Record, 10 times farther
- × 10
- 10 × 10
- ≈ 100 m
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Record distance
- 98.43 m
- Guinness-stated conversion
- 322 ft 11 in
- Rounded
- ≈ 323 ft
