...Larger airports for international flights generally have paved runways 2,000 m (6,600 ft) or longer. Many small airports have dirt, grass, or gravel runways, rather than asphalt or concrete.

These include considerations for safety margins during landing and takeoff. Typically, heavier aircraft require longer runways. The longest public-use runway in the world is at Qamdo Bangda Airport, in Bangda, Qamdo, China. It has a length of 5,500 m (18,045 ft).
