what is the measurement of a goal post
Goals are placed at the centre of each goal-line. These consist of two upright posts placed equidistant from the corner flagposts, joined at the top by a horizontal crossbar. The inner edges of the posts must be 7.32 metres (8 yd) apart, and the lower edge of the crossbar must be 2.44 metres (8 ft) above the ground. Nets are usually placed behind the goal, though are not required by the Laws.
