Generally runways at smaller airports are 1-2 miles depending on the size of aircraft that are going to be landing there. Your gib airports like O'Haire and LAX those runways are usually 2-3 miles long in case the plane needs extra stopping room for a mechanical issue.
The average length of a runway is not supported by any data given the amount of general aviation and international airports in the world, however runway distances range from 804ft to 24,120 feet (Area 51 Air Force Test Site runway).
they have to be 6000 ft but there are larger ones
The lengths vary. The longest is 7.38636364 mi. at Edwards Airforce Base according tohttp://en.wikipedia.org/wiki/List_of_longest_runways#Super_Longest_Runways
International Airport: 7000 feet - 14000 feet
Regional Airport: 3000 feet - 7000 feet
These are not actual requirements just averages
Runway 26L/09R at Gatwick airport is exactly 10,879 feet or 3,316 meters long.
Stansted's runway is 3,048 metres or 10,000 ft.
Most major airports cover an area of several square miles, they would need to be at least 2 miles long to accommodate a long enough runway to cope with todays modern Jets.
1 straight mile
There is no average length of a runway, according to wnysound.com and another answer on Ask.com.The first source (listed below) suggests that a runway length should "be two-thirds the length of your room."Consider your venue, especially backstage and seating needs.Sources:- http://wnysound.com/runway-stage/- What%20is%20the%20standard%20measurement%20for%20fashion%20show%20runwaysthere----Are you planning on becoming a model? :O if not... You don't need to worry about it :)

The standard runway length for planning purposes is about 10,000 ft
The required runway length depends on the payload and, the fuel on board the aircraft. If your looking at relatively full payload and, maximum weight on board you can see some 747's using full length runway departures which can be over 12,000 feet. So there really is not a required runway length till you get specific with payload and, fuel on board.
