Question 1

Why do places near the poles look larger on a Mercator map?

Accepted Answer

Mercator scale increases with latitude. The projection preserves local angles while stretching distances and areas progressively toward the poles.

Question 2

How much does Mercator enlarge area at 60 degrees latitude?

Accepted Answer

In the spherical Mercator model, linear scale at 60 degrees is twice the equatorial scale and local area is enlarged by a factor of four.

Question 3

Is the Mercator projection inaccurate?

Accepted Answer

Mercator is mathematically consistent and useful for navigation and conformal mapping. It becomes unsuitable when readers need to compare the relative area of regions across widely different latitudes.
