The November 11, 2026 puzzle ran from an NBA basketball at 24.3 cm to an American football field at 109.7 m — about 451× apart, drawing on sports. The pair furthest apart was round 1: an American football field is 1.6× as big as a Boeing 747.
Answer: American Football Field — 109.7 m. An American football field measures 109.7 m (length / span), which is 1.6× as big as the reference, a Boeing 747 at 70.7 m.
Goal line to goal line is 100 yards; end zones make the full field 120 yards.
Common miss: players tend to compress an American football field when it sits beside a Boeing 747 — big things get squeezed, small familiar things get stretched.
Answer: Olympic Swimming Pool — 50 m. An Olympic swimming pool measures 50 m (length / span), which is 1.3× as big as the reference, a Space Shuttle orbiter at 37.3 m.
An Olympic pool is exactly 50 metres long.
Common miss: players tend to compress an Olympic swimming pool when it sits beside a Space Shuttle orbiter — big things get squeezed, small familiar things get stretched.
Answer: American Football — 28 cm. An American football measures 28 cm (length / span), which is 1.2× as big as the reference, an NBA basketball at 24.3 cm.
An American football is measured along its long axis; the pointed ends make it read larger than it is.
Common miss: players tend to compress an American football when it sits beside an NBA basketball — big things get squeezed, small familiar things get stretched.
Answer: Hockey Stick — 1.6 m. A hockey stick measures 1.6 m (height), which is about 1.1× smaller than the reference, a refrigerator at 1.8 m.
A stick is fitted to reach between the chin and the nose when the player is standing on skates.
Common miss: players tend to inflate a hockey stick when it sits beside a refrigerator — big things get squeezed, small familiar things get stretched.
Answer: NBA Basketball — 24.3 cm. An NBA basketball measures 24.3 cm (length / span), which is about 1.2× smaller than the reference, an American football at 28 cm.
An NBA ball is regulated by circumference, about 75 cm, which works out to just under 25 cm across.
Common miss: players tend to inflate an NBA basketball when it sits beside an American football — big things get squeezed, small familiar things get stretched.
