Mens Playing area
Diagram of a men's college lacrosse field.
A standard lacrosse field is 110 yards (100 m) in length from each endline, and 60 yards (55 m) in width from the sidelines.
Field lacrosse goals are centered between each sideline, positioned 15 yards (14 m) from each endline and 80 yards (73 m) apart from one another. Positioning the goals well within the endlines allows play to occur behind them. The goal is 6 feet (1.8 m) wide by 6 feet (1.8 m) tall, with nets attached in a pyramid shape. Surrounding each goal is a circular area known as the "crease," measuring 18 feet (5.5 m) in diameter.
If a player enters the "crease" while shooting toward the goal, the referee will call a foul and the ball gets turned over to the other team.
A pair of lines, 20 yards (18 m) from both the midfield line and each goal line, divides the field into three sections. From each team's point of view, the one nearest its own goal is its defensive area, then the midfield area, followed by the attack or offensive area. These trisecting lines are called "restraining lines." A right angle line is marked 10 yards (9.1 m) from each sideline connecting each endline to the nearer restraining line, creating the "restraining box." If an official deems that a team is "stalling," that is not moving with offensive purpose while controlling the ball, the possessing team must keep the ball within the offensive restraining box to avoid a loss-of-possession penalty.
Field markings dictate player positioning during a face-off. A face-off is how play is started at the beginning of each quarter and after each goal. During a face-off, there are six players (without considering goalkeepers) in each of the areas defined by the restraining lines. Three midfielders from each team occupy the midfield area, while three attackmen and three of the opposing team's defensemen occupy each offensive area. These players must stay in these areas until possession is earned by a midfielder or the ball crosses either restraining line. Wing areas are marked on the field on the midfield line 10 yards (9.1 m) from each sideline. This line indicates where the two nonface-off midfielders per team lineup during a face-off situation. These players may position themselves on either side of the midfield line. During a face-off, two players lay their sticks horizontally next to the ball, head of the stick inches from the ball and the butt-end pointing down the midfield line. Once the official blows the whistle to start play, the face-off midfielders scrap for the ball to earn possession and the other midfielders advance to play the ball. If possession is won by the face-off player, he may move the ball himself or pass to a teammate.
The rules also require that substitution areas, a penalty box, coaches area, and team bench areas be designated on the field.

The size of the playing field depends on the players' age group. For U15 and U13 players, they must play on a regulation sized field with all appropriate markings. For U11, they must play on a regulation sized field with all appropriate markings whenever possible. Otherwise they may play on a modified field with reduced players. For U9 players the fields must be rectangular, between 60–70 yards in length and 30–40 yards in width to accommodate play on existing fields.
There are two different surroundings around the goal on both sides of the field; the eight meter arc and the 12 meter fan. When committing a major foul inside either of these areas, the offense regains the ball and has a direct opportunity to goal. If outside the 8-meter arc, but inside the fan, a "lane" to goal is cleared of all other players and the person who committed the foul is relocated 4 meters behind the offender. If inside the 8-meter-arc and a defensive foul occurs, all players that were previously inside the surrounding must take the most direct route out. The player who was fouled now moves to the nearest hash mark that is located around the edges of the arc and has a direct lane to goal. The defender who committed the foul is relocated on the 12-meter fan directly behind the shooter. If a player fouled another player not in the arc, the victim receives the ball and the player who fouled must back away at least 4 meters. All other players standing closer than 4 meters to the ball holder must also back away to give the girl room to move with the ball.
The shooting space rule in women's lacrosse is very important in keeping the players safe. It occurs when a defender moves into the offender's shooting lane to goal, at an angle that makes the defender at risk of being hit by the ball if the offender were to shoot.
