Compare country areas, not map widths
Size It Up Geography compares total surface area in square kilometres. All 35 countries use the same UN 2020 series, rounded to 1,000 km². Keeping one dataset makes the answers consistent instead of mixing land-only figures with total areas from different years.
What does the outline show?
A long, narrow country can cover less area than a shorter, wider one. Read the green reference’s square-kilometre label and judge the filled shape, not just its height. The generalized silhouettes are normalized to the stated areas; they are not detailed boundary surveys.
Why does the slider change both dimensions?
Area grows with width and height together. Doubling both makes four times the area, so an area estimate of 2× needs only about 1.41× the width and height. A familiar wall map can also distort your intuition: use the reference in this round as your anchor.
Pick a region to practice
Start with a regional pool if its outlines are familiar, or choose Around the world for a mix. Each game selects five comparisons from the chosen pool, so the countries can appear again when you replay.
The Americas
Eight countries across North and South America.
Europe
Eight European countries, compared by total surface area.
Africa
Seven countries across the African continent.
Asia & Pacific
Twelve countries from Asia, Australia and New Zealand.
