The diameter of the earth varies - its diameter at the equator is 12,756.32 kilometers or 7,926.41 miles However, at the poles it is 12,715.43 kilometers or 7,901.00 miles. Since the earth is 59 km or 25 miles wider than it is tall, it bulges at the equator. The earths shape is not round but geoid.
