The goal is the combination of the crossbar and goal posts that teams attempt to defend and score into. The crossbar is the top bar across the goal, held up by goal posts. The goal posts, also called the uprights hold up the crossbar and make up the goal. The goals are white with a white netting.
The uprights are the two poles that run vertically on each side of the goal that connects to the cross bar. They are 8 feet high and mark the bounds of the goal. If a ball deflects off of the upright into the goal, the goal counts.
The crossbar is the bar that runs horizontally on top of the uprights. It is 24 feet in length and also 8 feet off the ground. If a ball skims the crossbar and goes into the goal, the goal counts.
Sizes of goals may vary for younger leagues. Many high school goal sizes are 7 feet high and 21 feet across as opposed to 8 feet by 24. Practice nets are available in varying sizes if teams wish to work with a smaller area for shooting.
Following a goal, play restarts with a kick-off, identical to the one at the beginning of a match. The team that conceded the goal puts the ball into play. The game clock does not stop after a goal, so if it is late in the game and the team that is behind just scored a goal or tied the game, you might see their players rush to grab the ball and reset quickly for a kick-off.
