City bus 12 m

Target · length

Orca 8 m

Correct ratio: target ÷ reference = 0.6667. The target’s length is approximately 0.6667× the reference’s length.

A large orca is around two thirds the length of a standard city bus.

A representative large adult; individual lengths vary.

Reference · length

Boeing 747-8 76.3 m

Target · length

Space Shuttle 37.2 m

Correct ratio: target ÷ reference = 0.4875. The target’s length is approximately 0.4875× the reference’s length.

The Space Shuttle orbiter is just under half as long as a Boeing 747-8.

Orbiter length, not the launch stack.

Reference · length

Space Shuttle 37.2 m

Target · length

Blue whale 29.9 m

Correct ratio: target ÷ reference = 0.8038. The target’s length is approximately 0.8038× the reference’s length.

A record-size blue whale is only several metres shorter than a Space Shuttle orbiter.

An upper-end body length, not the average size of all blue whales.

Reference · height

Door 2.03 m

Target · height

Adult 1.7 m

Correct ratio: target ÷ reference = 0.8374. The target’s height is approximately 0.8374× the reference’s height.

A typical adult is roughly five sixths the height of a standard interior door.

Reference · diameter

Moon 3,474.8 km

Target · diameter

Death Star 160 km

Correct ratio: target ÷ reference = 0.0461. The target’s diameter is approximately 0.0461× the reference’s diameter.

A 160-kilometre Death Star is enormous beside a city, yet tiny compared with the Moon’s diameter.

Reference · east–west span

Iceland 500 km

Target · east–west span

France 950 km

Correct ratio: target ÷ reference = 1.9. The target’s east–west span is approximately 1.9× the reference’s east–west span.

Metropolitan France is close to twice Iceland’s approximate east–west width.

Approximate linear extent along the named axis; this does not compare land area.

Reference · north–south span

Italy 1,200 km

Target · north–south span

Madagascar 1,600 km

Correct ratio: target ÷ reference = 1.333. The target’s north–south span is approximately 1.333× the reference’s north–south span.

Madagascar runs about one third farther north to south than the Italian peninsula and islands.

Reference · east–west span

Australia 4,007 km

Target · east–west span

Brazil 4,328 km

Correct ratio: target ÷ reference = 1.08. The target’s east–west span is approximately 1.08× the reference’s east–west span.

Brazil is only modestly wider east to west than mainland Australia and Tasmania together.
