The poles are infinitely large (so the map cuts them off)
The map's distortion doesn't just grow near the poles — it runs to infinity, which is why every web map is secretly cropped.

Both panels are drawn to the same scale. On the left, each country is the size the Mercator map gives it; on the right, its true size with the latitude distortion removed.A lie with no ceiling
Most of the latitude tax is finite — double at 45°, quadruple at 60°. But it never
stops climbing, and as you approach the pole it doesn't just get large, it runs to
infinity. A single point sitting exactly on the North Pole would have to be drawn
infinitely big. Greenland, highlighted here, is the closest large landmass to that
runaway, and the map inflates it accordingly.
The numbers
How much too big the map draws a shape, as its centre climbs toward the pole:
- 60° → 4×
- 75° → ~15×
- 80° → ~33×
- 84° (the map's top edge) → ~92×
- 85° → ~132×
- 90° (the pole) → infinite
Greenland makes it tangible: its centre (~70.6° N) is drawn ~9× too big, but its
northern tip reaches 83.6° N, where the map blows it up by roughly 80×. Its
honest area is just 2,142,677 km².
Why the map lies
The area tax is sec²(latitude) = 1 / cos²(latitude). As latitude approaches 90°,
cos(latitude) approaches zero, so dividing by its square sends the factor toward
infinity. The map literally cannot draw the poles at any finite size — so web maps
(this one included) simply crop the world near ±85° and throw the rest away.
Try it
Drag Greenland straight north toward the pole. The readout climbs past 9×, through
the teens, into the dozens — and then the shape jams against the very top of the map
and can go no further. That hard edge is the crop: the place where the lie became
too big to draw.
