A cricket field consists of a large circular or oval-shaped grassy ground on which the game of cricket is played. There are no fixed dimensions for the field but its diameter usually varies between 450 feet (137 m) and 500 feet (150 m). Cricket is unusual among major sports (along with Golf, Australian rules football and baseball) in that there is no official rule for a fixed-shape ground for professional games. The cricket ground can vary from being almost a perfect circle, to being an extremely elongated oval. On most grounds, a rope demarcates the perimeter of the field and is known as the boundary. A cricket pitch is 22 yards long.
The ICC Standard Playing Conditions define the minimum and maximum size of the playing surface for international matches. Law 19.1 of ICC Test Match Playing Conditions states:
"The playing area shall be a minimum of 150 yards (137.16 metres) from boundary to boundary square of the pitch, with the shorter of the two square boundaries being a minimum 65 yards (59.43 metres). The straight boundary at both ends of the pitch shall be a minimum of 70 yards (64.00 metres). Distances shall be measured from the centre of the pitch to be used. In all cases the aim shall be to provide the largest playing area, subject to no boundary exceeding 90 yards (82.29 meters) from the centre of the pitch to be used. "
In addition, the conditions require a minimum 3 yard gap between the "rope" and the surrounding fencing or advertising boards. This is to allow the players to dive without hurting themselves.
The conditions contain a grandfather clause, which exempts stadiums built before October 2007. However, most stadiums which regularly host international games easily meet the minimum dimensions.
It is worth noting that based on these guidelines, a cricket field must have at least 16,000 square yards ((150+3+3)/2*(70+70+3+3-22/2)/2*pi) of grass area. A more realistic test-match stadium would have more than 20,000 square yards of grass (having a straight boundary of about 80m). In contrast an association football field needs only about 9,000 square yards of grass, and an Olympic stadium would contain 13,500 square yards of grass within its 400m running track, making it impossible to play international cricket matches unless the stadium was specifically built for cricket. However the Stadium Australia which hosted the Sydney Olympics in 2000 had its running track turfed over and 30,000 seats removed to make it possible to play cricket in the stadium, at a cost of A$80 million. This is one of the reasons cricket games generally cannot be hosted outside the traditional cricket playing countries, and a few non-test nations like Canada, the UAE, and Kenya that have built test-match standard stadiums.
Most of the action takes place in the centre of this ground, on a rectangular clay strip usually with short grass called the pitch. The pitch measures 22 yards (20 m) long.
At each end of the pitch three upright wooden stakes, called the stumps, are hammered into the ground. Two wooden crosspieces, known as the bails, sit in grooves atop the stumps, linking each to its neighbour. Each set of three stumps and two bails is collectively known as a wicket. One end of the pitch is designated the batting end where the batsman stands and the other is designated the bowling end where the bowler runs in to bowl. The area of the field on the side of the line joining the wickets where the batsman holds his bat (the right-hand side for a right-handed batsman, the left for a left-hander) is known as the off side, the other as the leg side or on side.
Parts of the field
For a one-innings match played over a set number of fair deliveries, there are two additional field markings. A painted oval is made by drawing a semicircle of 30 yards (27.4 m) radius from the centre of each wicket with respect to the breadth of the pitch and joining them with lines parallel, 30 yards (27.4 m) to the length of the pitch. This line, commonly known as the circle, divides the field into an infield and outfield. Two circles of radius 15 yards (13.7 m), centred at middle stump guard on the popping crease and often marked by dots, define the close-infield. The infield, outfield, and the close-infield are used to enforce fielding restrictions.
