A cricket field is a large grass field on which the game of cricket is played. Although generally oval in shape, there is a wide variety within this: some are almost perfect circles, some elongated ovals and some entirely irregular shapes with little or no symmetry – but they will have entirely curved boundaries, almost without exception. There are no fixed dimensions for the field but its diameter usually varies between 450 and 500 feet (140 and 150 m) for men's cricket, and between 360 feet (110 m) and 420 feet (130 m) for women's cricket. 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. On most grounds, a rope demarcates the perimeter of the field and is known as the boundary.

In cricket, the length of the inner circle from the wicket is 30 yards. Use of 30 Yards A power play involves placing 2 players outside the 30 yard box. In T20 for 6 overs and in ODI cricket for 10 overs as per rule each team can keep 2 players outside this 30 yards.

Within the boundary and generally as close to the centre as possible will be the square which is an area of carefully prepared grass upon which cricket pitches can be prepared and marked for the matches. The pitch is where batsmen hit the bowled ball and run between the wickets to score runs, while the fielding team tries to return the ball to either wicket to prevent this.
