ROUND 1
House Key — 6 cm
Answer: a house key measures 6 cm (length / span), which is about 1.3× smaller than the reference, a hockey puck at 7.6 cm.
Keys settle around 6 cm because that is what the lock cylinder needs, not the hand.
Common miss: players tend to inflate a house key when it sits beside a hockey puck — big things get squeezed, small familiar things get stretched.
Answer: a three-seat sofa measures 2.2 m (length / span), which is 1.1× as big as the reference, a queen bed at 2 m.
Two metres of sofa is mostly frame and armrest; the seating itself is nearer 1.6 m.
Common miss: players tend to compress a three-seat sofa when it sits beside a queen bed — big things get squeezed, small familiar things get stretched.
Answer: a US interior door measures 2 m (height), which is 1.1× as big as the reference, a refrigerator at 1.8 m.
The familiar American interior door is usually 80 inches tall.
Common miss: players tend to compress a US interior door when it sits beside a refrigerator — big things get squeezed, small familiar things get stretched.
Answer: a dining chair measures 90 cm (height), which is about 1.1× smaller than the reference, an acoustic guitar at 1 m.
Chair dimensions are standardised around the table: 45 cm to the seat, 90 cm to the top of the back.
Common miss: players tend to inflate a dining chair when it sits beside an acoustic guitar — big things get squeezed, small familiar things get stretched.
