Both maps below show Montenegro highlighted. The old Mercator map (1569) inflates Montenegro about 1.9× at 43°, and the new Equal Earth map shows it at its true 13,888 km². Pan or zoom either map and the other follows, so the difference is visible at every scale.
That 1.9× inflation is why Montenegro dominated old schoolbook maps and maps of the world's great powers. Hover Montenegro on either map to highlight it on both at once, then compare it with Greenland.
Montenegro: key figures
| True area | On the old Mercator map | Distortion vs truth |
|---|
| Montenegro | 13,888 km² | 25,787 km² | 1.9× |
| Greenland | 2,166,086 km² | 25,576,494 km² | 11.8× |
| Africa | 30,370,000 km² | n/a | n/a |
Old maps drew Montenegro at about 25,787 km². The truth is 13,888 km², a difference of 86% that school atlases carried for centuries.
