ROUND 1
Birthday Cake — 25 cm
Answer: a birthday cake measures 25 cm (length / span), which is almost exactly the same size as the reference, an NBA basketball at 24.3 cm.
A 25 cm round is the standard “serves twelve” size.
How people guessed: across 26 runs the typical guess was 21.2 cm — 15% too small.
Answer: a game controller measures 16 cm (length / span), which is 1.1× as big as the reference, a hot dog at 15 cm.
Controller width has hardly moved since the 1990s — hands did not get bigger.
How people guessed: across 26 runs the typical guess was 21.2 cm — 32% too large. The most common miss is picturing a game controller far bigger than a hot dog really allows.
Answer: the Sun measures 1,392,700 km (length / span), which is 2142615385× as big as the reference, a French baguette at 65 cm.
The Sun is about 1.39 million kilometres in diameter.
How people guessed: across 26 runs the typical guess was 52 m — 100% too small. The most common miss is picturing the Sun far smaller than a French baguette really allows.
Answer: the contiguous United States measures 4,500 km (length / span), which is 1.1× as big as the reference, Australia at 4,000 km.
The lower 48 stretch roughly 4,500 kilometres coast to coast.
How people guessed: across 26 runs the typical guess was 9,215.6 km — 105% too large. The most common miss is picturing the contiguous United States far bigger than Australia really allows.
