DAILY NO. 10 · VERIFIED MEASUREMENTS
The five geography objects from the Size It Up puzzle on September 10, 2026, with the measured size of each, the reference it was compared against, a source you can check, and how the community's guesses landed. Want the surprise first? Replay this puzzle — archived days never touch your streak.
Answer: the contiguous United States measures 4,500 km (length / span), which is almost exactly the same size as the reference, Brazil at 4,320 km.
The lower 48 stretch roughly 4,500 kilometres coast to coast.
Common miss: players tend to compress the contiguous United States when it sits beside Brazil — big things get squeezed, small familiar things get stretched.
Answer: Hawaiʻi Island measures 150 km (length / span), which is about 6.7× smaller than the reference, metropolitan France at 1,000 km.
The Big Island is larger than all the other Hawaiian islands combined, and still growing.
Common miss: players tend to inflate Hawaiʻi Island when it sits beside metropolitan France — big things get squeezed, small familiar things get stretched.
Answer: Greenland measures 2,670 km (height), which is 2.2× as big as the reference, California at 1,240 km.
The span is real, but Mercator maps still inflate Greenland’s area by about fourteen times.
Common miss: players tend to compress Greenland when it sits beside California — big things get squeezed, small familiar things get stretched.
Answer: Australia measures 4,000 km (length / span), which is about 1.1× smaller than the reference, the contiguous United States at 4,500 km.
Australia is nearly as wide as the contiguous United States, with a tenth of the population.
Common miss: players tend to inflate Australia when it sits beside the contiguous United States — big things get squeezed, small familiar things get stretched.
Answer: Africa measures 8,000 km (height), which is 3× as big as the reference, Greenland at 2,670 km.
Africa spans roughly 8,000 kilometres from north to south.
Common miss: players tend to compress Africa when it sits beside Greenland — big things get squeezed, small familiar things get stretched.
