What is the worst map projection?

The worst map projection is often considered to be the Mercator projection, particularly for representing large areas. While it preserves angles and shapes, it significantly distorts sizes, especially near the poles, making Greenland and Antarctica appear much larger than they are relative to equatorial regions. This distortion can lead to misconceptions about the true scale and importance of different countries and regions. In contexts where accurate area representation is crucial, projections like the Peters or Robinson may be preferred.
