Airports are vast pieces of infrastructure that stretch across tens or hundreds of square kilometres. Using land area, this list looks at the largest airports in the world by physical size, ranking them purely on how much ground they occupy.
Source and methodology
This ranking is based on data compiled by World Atlas, which measures the total land area owned and managed by each airport authority. The figures reflect the overall airport footprint, including runways, terminals, support facilities, and undeveloped land reserved for future expansion. Rankings are ordered by total area, not by passenger traffic or flight volume.
The largest airports in the world by land area
1. King Fahd International Airport, Saudi Arabia: 776sqkm
The largest airport in the world by a staggering margin, King Fahd International Airport sprawls across the desert near Dammam, with much of its land reserved for long-term expansion.
2. Denver International Airport, USA: 137.8sqkm
The biggest airport in North America, Denver’s vast footprint allows for long runways, large aircraft operations, and room to grow in extreme weather conditions.
