Think: roughly the size of China or Europe. About 50× the size of the UK.
Japan
378,000 km²
Similar to Germany or California. About 26× smaller than the USA.
France
551,000 km²
The largest country in the EU. About 1.5× the size of Japan.

The travel-time anchor
A commercial plane flies ~900 km/h. So: 1,000 km ≈ 1 hour of flying. Paris→Rome (~1,100 km) = just over 1 hour. London→New York (~5,500 km) = ~6 hours. Once you know this, you can estimate any flight time instantly.
Part C · landmark heights
How tall is it? (heights in metres)
Burj Khalifa (Dubai)
830 m — tallest building
Eiffel Tower (Paris)
330 m
Statue of Liberty
93 m total
Big Ben tower
96 m
Notre-Dame spire
81 m
10-storey building
30 m
Rule: 1 floor ≈ 3 metres. A 10-story building = 30 m. The Eiffel Tower = about 110 floors stacked.
Eiffel Tower
330 m
Including antenna. Original structure to roof: 300 m. About 110 storeys tall.
Mount Everest
8,849 m
That's 8.8 km straight up. About 27 Eiffel Towers stacked. Nearly as tall as planes cruise.
Plane cruising altitude
~10,000 m
10 km up. Everest reaches 88% of that height — almost into plane territory.
Part D · anchor numbers to memorize

Eiffel Tower height
1 floor ≈ 3 m, so it equals ~110 floors
Part E · test yourself
1. Someone says the flight from Tokyo to Los Angeles is about 9 hours. Does that make sense?
Yes, perfectly. Tokyo to LA is ~8,800 km. At ~900 km/h that's about 9.8 hours. So 9 hours is a reasonable estimate. Anchor: every 1,000 km ≈ 1 hour of flying.
2. How many times bigger is the USA than Japan?
About 26 times bigger. USA = 9.8M km², Japan = 378,000 km². 9,800,000 ÷ 378,000 ≈ 26. Japan would fit inside the USA 26 times over — and yet Japan's population (125M) is about 40% of the USA's (335M), packed into a tiny area.
3. A building has 50 floors. Roughly how tall is it in metres?
About 150 m. One floor ≈ 3 m. 50 × 3 = 150 m. For context, the Eiffel Tower (330 m) is about the height of a 110-floor building. Most city skyscrapers you see are in the 150–400 m range.
4. Paris to Rome by road is about 1,400 km. At 120 km/h on a motorway, how long would the drive take?
About 11–12 hours of pure driving (1,400 ÷ 120 ≈ 11.7 hours). In reality, with stops, borders, and traffic it'd be closer to 14–15 hours. That's why most people fly — the same journey takes just over 2 hours by air.
5. Is Europe larger or smaller than the USA in area?
Roughly the same size — and this surprises most people. Europe (all countries combined) is about 10.5M km². The USA is 9.8M km². They're almost identical in area. But Europe has ~750 million people vs the USA's ~335 million — more than twice as many people packed into roughly the same space, spread across 44 countries.
