Both maps below show Saudi Arabia highlighted. The old Mercator map (1569) inflates Saudi Arabia about 1.2× at 24°, and the new Equal Earth map shows it at its true 2,149,690 km². Pan or zoom either map and the other follows, so the difference is visible at every scale.
That 1.2× inflation is why Saudi Arabia dominated old schoolbook maps and maps of the world's great powers. Hover Saudi Arabia on either map to highlight it on both at once, then compare it with Greenland.
Saudi Arabia: key figures
| True area | On the old Mercator map | Distortion vs truth |
| Saudi Arabia | 2,149,690 km² | 2,579,198 km² | 1.2× |
| Greenland | 2,166,086 km² | 25,576,494 km² | 11.8× |
| Africa | 30,370,000 km² | n/a | n/a |
Old maps drew Saudi Arabia at about 2,579,198 km². The truth is 2,149,690 km², a difference of 20% that school atlases carried for centuries.
