Answer & explanation
Official answer
80
Pringles
How to estimate it
Fermi’s official “Napkin math”
Picture the can. It's about 9 inches tall and it's nearly all chips. How thick is one chip in the stack? They nest tight, so maybe 10 to an inch.
- Can height
- ~9 in
- Chips per inch
- × 10
- 9 × 10
- ≈ 90
Picture the can. It's about 25 centimeters tall and it's nearly all chips. How thick is one chip in the stack? They nest tight, so maybe 3 millimeters each.
- Can height
- ~25 cm
- One chip in the stack
- ÷ 3 mm
- 250 mm ÷ 3 mm
- ≈ 83
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.

- Pringles Original label, one 1 oz (28 g) serving
- about 15 crisps
- 15 crisps × 5.2 oz
- ≈ 78
- MEL Magazine hand count, three Original cans (2021)
- 79, 79, 78
- ≈
