What is the size of goal post and concrete foundation for 7.32 x 2.44 goals?

For a standard football goal measuring 7.32 meters wide and 2.44 meters high, the size of the concrete foundation should typically extend at least 1 meter beyond each post and 0.5 meters in front and behind the goal. This means a concrete foundation of approximately 9.32 meters wide (including extensions) and 1 meter deep is recommended to ensure stability. The thickness of the concrete should be at least 10-15 cm to adequately support the goal structure.
