Both maps below show Czechia highlighted. The old Mercator map (1569) inflates Czechia about 2.4× at 50°, and the new Equal Earth map shows it at its true 78,871 km². Pan or zoom either map and the other follows, so the difference is visible at every scale.
That 2.4× inflation is why Czechia dominated old schoolbook maps and maps of the world's great powers. Hover Czechia on either map to highlight it on both at once, then compare it with Greenland.
Czechia: key figures
| True area | On the old Mercator map | Distortion vs truth |
|---|
| Czechia | 78,871 km² | 188,833 km² | 2.4× |
| Greenland | 2,166,086 km² | 25,576,494 km² | 11.8× |
| Africa | 30,370,000 km² | n/a | n/a |
Old maps drew Czechia at about 188,833 km². The truth is 78,871 km², a difference of 139% that school atlases carried for centuries.
