ROUND 1
Olympic Swimming Pool — 50 m
Answer: an Olympic swimming pool measures 50 m (length / span), which is about 1.4× smaller than the reference, a Boeing 747 at 70.7 m.
An Olympic pool is exactly 50 metres long.
Common miss: players tend to inflate an Olympic swimming pool when it sits beside a Boeing 747 — big things get squeezed, small familiar things get stretched.
Answer: an American football measures 28 cm (length / span), which is about 1.3× smaller than the reference, a large pizza at 35.6 cm.
An American football is measured along its long axis; the pointed ends make it read larger than it is.

Answer: a surfboard measures 2 m (height), which is almost exactly the same size as the reference, a US interior door at 2 m.
A two-metre shortboard is smaller than most people picture — longboards start near three metres.
Common miss: players tend to inflate a surfboard when it sits beside a US interior door — big things get squeezed, small familiar things get stretched.
