Sport Field Plans

"A football pitch (also known as a football field or soccer field) is the playing surface for the game of football made of turf. Its dimensions and markings are defined by Law 1 of the Laws of the Game, "The Field of Play".
All line markings on the pitch form part of the area which they define. ...
Pitch boundary.
The pitch is rectangular in shape. The longer sides are called touchlines. The other opposing sides are called the goal lines. ... The two touch lines must also be of the same length... in international matches, the goal lines must be between 64 and 75 m (70 and 80 yd) long and the touchlines must be between 100 and 110 m (110 and 120 yd). All lines must be equally wide, not to exceed 12 centimetres (5 in). The corners of the pitch are demarcated by corner flags. ...
Goals.
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.
Goalposts and crossbars must be white, and made of wood, metal or other approved material." [Association football pitch. Wikipedia]

"Volleyball is a team sport in which two teams of six players are separated by a net. Each team tries to score points by grounding a ball on the other team's court under organized rules. It has been a part of the official program of the Summer Olympic Games since 1964. ...
The court dimensions.
A volleyball court is 18 m (59 ft) long and 9 m (29.5 ft) wide, divided into 9 m × 9 m halves by a one-meter (40-inch) wide net. The top of the net is 2.43 m (8 ft 0 in) above the center of the court for men's competition, and 2.24 m (7 ft 4 in) for women's competition, varied for veterans and junior competitions.
The minimum height clearance for indoor volleyball courts is 7 m (23 ft), although a clearance of 8 m (26 ft) is recommended.
A line 3 m (9.84 ft) from and parallel to the net is considered the "attack line". This "3 meter" (or "10-foot") line divides the court into "back row" and "front row" areas (also back court and front court). These are in turn divided into 3 areas each: these are numbered as follows, starting from area "1", which is the position of the serving player.
After a team gains the serve (also known as siding out), its members must rotate in a clockwise direction, with the player previously in area "2" moving to area "1" and so on, with the player from area "1" moving to area "6".
The team courts are surrounded by an area called the free zone which is a minimum of 3 meters wide and which the players may enter and play within after the service of the ball. All lines denoting the boundaries of the team court and the attack zone are drawn or painted within the dimensions of the area and are therefore a part of the court or zone. If a ball comes in contact with the line, the ball is considered to be "in". An antenna is placed on each side of the net perpendicular to the sideline and is a vertical extension of the side boundary of the court. A ball passing over the net must pass completely between the antennae (or their theoretical extensions to the ceiling) without contacting them." [Volleyball. Wikipedia]
