How fast 737 at takeoff?

The Boeing 737 typically takes off at a speed between 150 to 180 knots (about 173 to 207 mph or 278 to 333 km/h), depending on factors like its weight, configuration, and environmental conditions. Smaller variants, like the 737-700, may take off at lower speeds, while larger models, like the 737-900, might require higher speeds. The exact speed is determined during the pre-flight calculations by the flight crew.
