What is the circumference of the earth?

The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers).

But, if you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km). This the earth is a tad wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).

Learn more about the size and shape of the earth from my article on measuring the earth and earth facts and figures.
