The October 22, 2026 puzzle ran from a golf ball at 4.3 cm to an American football field at 109.7 m — 3 orders of magnitude apart, drawing on sports. The pair furthest apart was round 1: a basketball hoop is 1.5× as big as a US interior door.
Answer: Basketball Hoop — 3 m. A basketball hoop measures 3 m (height), which is 1.5× as big as the reference, a US interior door at 2 m.
The rim is exactly 10 feet above the floor.
Common miss: players tend to compress a basketball hoop when it sits beside a US interior door — big things get squeezed, small familiar things get stretched.
Answer: Tennis Racket — 68.5 cm. A tennis racket measures 68.5 cm (height), which is 1.2× as big as the reference, a violin at 59 cm.
The rules allow up to 73.7 cm, but almost every player uses something just under 69 cm.
Common miss: players tend to compress a tennis racket when it sits beside a violin — big things get squeezed, small familiar things get stretched.
Answer: American Football Field — 109.7 m. An American football field measures 109.7 m (length / span), which is almost exactly the same size as the reference, the Hollywood Sign at 106.7 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 the Hollywood Sign — big things get squeezed, small familiar things get stretched.
Answer: Surfboard — 2 m. A surfboard measures 2 m (height), which is 1.1× as big as the reference, a refrigerator at 1.8 m.
A two-metre shortboard is smaller than most people picture — longboards start near three metres.
Common miss: players tend to compress a surfboard when it sits beside a refrigerator — big things get squeezed, small familiar things get stretched.
Answer: Golf Ball — 4.3 cm. A golf ball measures 4.3 cm (length / span), which is about 1.4× smaller than the reference, a house key at 6 cm.
A golf ball cannot be smaller than 42.67 mm in diameter.
Common miss: players tend to inflate a golf ball when it sits beside a house key — big things get squeezed, small familiar things get stretched.
