Africa Is Larger Than You Think

The common world map, a familiar sight in classrooms and online, presents a significantly distorted view of our planet's geography. This is due to the widespread use of the Mercator projection, a cartographic method developed by Gerardus Mercator in 1569. While revolutionary for its time and invaluable for nautical navigation because it preserves angles and directions, the Mercator projection dramatically inflates the size of landmasses the further they are from the equator. This results in a skewed perception of the true scale of continents. For example, on a Mercator map, Greenland can appear to be roughly the same size as Africa, when in reality, Africa is about 14 times larger.

This cartographic distortion has led to a widespread underestimation of Africa's immense size. The continent's actual land area is approximately 30.37 million square kilometers (11.7 million square miles), which is larger than the United States, China, India, Japan, and much of Europe combined. Because Africa straddles the equator, its representation on a Mercator map is subject to less size distortion than landmasses in the higher latitudes of the Northern Hemisphere, such as Europe and North America, which appear disproportionately large.

The historical prevalence of the Mercator projection, especially during the late 19th and early 20th centuries, has been criticized for potentially reinforcing a Eurocentric worldview by visually exaggerating the size and perceived importance of northern nations. In response to this, alternative map projections have been proposed to offer a more accurate representation of area. The Gall-Peters projection, for instance, preserves the relative sizes of landmasses, offering a starkly different and more accurate visual comparison of the continents. Viewing these alternative maps helps to correct the ingrained misconception of Africa's size and fosters a more accurate understanding of global geography.
