Airports are more than just terminals and runways—they are sprawling cities in their own right. Some are so massive that they cover more land than entire countries or metropolitan areas. From deserts to farmlands, these aviation giants stretch across tens—and even hundreds—of square kilometres.

Based on data compiled by World Population Review, this list ranks the largest airports in the world in 2026 by total land area. The ranking is determined purely by physical size, not passenger traffic or flight volume. It includes runways, terminals, cargo zones, support facilities and undeveloped land reserved for future expansion.
