ROUND 1
House Key — 6 cm
Answer: a house key measures 6 cm (length / span), which is about 1.3× smaller than the reference, an apple at 8 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 an apple — big things get squeezed, small familiar things get stretched.
Answer: a three-seat sofa measures 2.2 m (length / span), which is about 1.1× smaller than the reference, an adult horse at 2.4 m.
Two metres of sofa is mostly frame and armrest; the seating itself is nearer 1.6 m.
Common miss: players tend to inflate a three-seat sofa when it sits beside an adult horse — big things get squeezed, small familiar things get stretched.
Answer: a refrigerator measures 1.8 m (height), which is about 1.1× smaller than the reference, a US interior door at 2 m.
A full-height fridge-freezer stops just short of eye level for most adults.
Common miss: players tend to inflate a refrigerator when it sits beside a US interior door — big things get squeezed, small familiar things get stretched.
