The October 11, 2026 puzzle ran from a smartphone at 14.7 cm to Manhattan Island at 21.6 km — 5 orders of magnitude apart, drawing on geography, animals, sports, dinosaurs, technology. The pair furthest apart was round 1: Manhattan Island is 10630× as big as a US interior door.
Answer: Manhattan Island — 21.6 km. Manhattan Island measures 21.6 km (height), which is 10630× as big as the reference, a US interior door at 2 m.
Manhattan is about 21.6 kilometres long.
How people guessed: across 13 runs the typical guess was 162.6 m — 99% too small. The most common miss is picturing Manhattan Island far smaller than a US interior door really allows.
Answer: Adult Horse — 2.4 m. An adult horse measures 2.4 m (length / span), which is about 1.1× smaller than the reference, a concert grand piano at 2.7 m.
A riding horse is roughly as long as a dairy cow.
How people guessed: across 13 runs the typical guess was 2.7 m — 11% too large.
Answer: Soccer Goal — 7.3 m. A soccer goal measures 7.3 m (length / span), which is 1.2× as big as the reference, an American pickup truck at 5.9 m.
A full-size association football goal is 7.32 metres wide.
How people guessed: across 13 runs the typical guess was 10.5 m — 43% too large. The most common miss is picturing a soccer goal far bigger than an American pickup truck really allows.
Answer: Ankylosaurus — 8 m. An Ankylosaurus measures 8 m (length / span), which is about 1.1× smaller than the reference, a Triceratops at 9 m.
The tail club weighed tens of kilos and could swing hard enough to break bone.
How people guessed: across 13 runs the typical guess was 11.1 m — 38% too large. The most common miss is picturing an Ankylosaurus far bigger than a Triceratops really allows.
Answer: Smartphone — 14.7 cm. A smartphone measures 14.7 cm (height), which is 1.2× as big as the reference, a soda can at 12.2 cm.
Phones stopped growing at roughly the limit of what a thumb can reach one-handed.
How people guessed: across 13 runs the typical guess was 14.5 cm — almost exactly right.
