Answer: a double bass measures 1.8 m (height), which is about 1.1× smaller than the reference, a US interior door at 2 m.

A concert grand can be more than 2.7 metres long.
Common miss: players tend to compress a concert grand piano when it sits beside a Velociraptor — big things get squeezed, small familiar things get stretched.
Answer: an alto saxophone measures 74 cm (height), which is about 1.4× smaller than the reference, an acoustic guitar at 1 m.
The bend and the bell fold more than a metre of tubing into 74 cm of instrument.

Forty-seven strings holding close to a tonne of combined tension.
Common miss: players tend to compress a concert harp when it sits beside a refrigerator — big things get squeezed, small familiar things get stretched.
Answer: a drum kit measures 1.5 m (length / span), which is about 1.2× smaller than the reference, a road bicycle at 1.8 m.
