Field of Play

The game of cricket is played on a big circular/oval ground with a rectangular pitch as the centre where batting and bowling takes place. A boundary marks the perimeter (137-150 m) of the field, and can take the form of a fence, rope or line.

As per standard guidelines, the playing area should be a minimum of 137.16 m from boundary to boundary square of the pitch, with the shorter of the two square boundaries a minimum of 59.43 m. The straight boundary at both ends of the pitch should be minimum 64 m long as measured from centre of the pitch.

Regulation lengths are as follows:

  • Pitch: The pitch is a rectangular area of the ground 20.12 m in length and 3.05 m in breadth. The stumps are rooted at both ends with distance between them of 22 yards (20.12 m). It is bounded at either end by the bowling creases and on either side by imaginary lines, one each side of the imaginary line joining the centres of the two middle stumps. The various lines marked on the pitch are as follows,
    • Bowling crease: It is the back edge of the crease marking which marks the end of the pitch and is 2.64 m in length.  
    • Popping crease: It is the back edge of the crease marking which is in front of and parallel to the bowling crease and is 1.22 m from it. The popping crease should be marked to a minimum of 1.83 m on either side of the imaginary line joining the centres of the two middle stumps and is considered to be unlimited in length.
    • Return crease: The return creases are the inside edges of the crease markings which is at right angles to the popping crease at a distance of 1.32 m either side of the imaginary line joining the centres of the two middle stumps. Each return crease should be marked from the popping crease to a minimum of 2.44 m behind it and is considered to be unlimited in length.

  • Infield: The infield if formed by drawing two semi-circles with a radius of 27.43 m on the field of play. The centre of these circles is the middle stump at either end of the pitch.
