How to estimate it

Fermi’s official “Napkin math”

Giant pumpkins get lifted onto the scale with a forklift. Picture one next to a dairy cow, which weighs about 1,500 pounds. How many cows is the record holder? It's wider than a cow is long, so call it two.

Dairy cow
~1,500 lb
Record pumpkin, in cows
× 2
1,500 × 2
≈ 3,000 lb

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

Source calculation & reference
