The takeoff distance required for a Boeing 737 can vary depending on several factors, including the specific model of the 737, the weight of the aircraft, the altitude of the airport, and environmental conditions such as temperature and wind.

Generally, for a Boeing 737-800, the takeoff distance at sea level under standard conditions (ISA) is approximately 2,500 to 3,000 feet (about 760 to 910 meters). However, this distance can increase significantly with higher weights, higher elevations, or adverse weather conditions.

For example:

• At higher altitudes or with a heavier load, the takeoff distance can exceed 4,000 feet (about 1,220 meters).
• The Boeing 737 MAX series may have slightly different performance characteristics, but they are generally in a similar range.

For precise figures, it's always best to refer to the specific aircraft's flight manual or performance charts, as they provide detailed information tailored to the aircraft's configuration and operating conditions.
