In cricket, the boundary is the perimeter of a Cricket field. It is also the term given to a scoring shot where the ball is hit to, or beyond, that perimeter, which generally earns four or six runs for the batting team.
Briefly, if the ball is struck by the batter and rolls or bounces over the boundary (or just touches it) it is known as a "four", and scores four runs, whereas if it flies over (or touches) the boundary, without touching the ground before that, it is called a "six", and scores six runs. There are rules covering every possible situation, including the fairly common one when a fielder is in the air beyond the boundary when they catch or strike the ball with their hand or another part of the body.
A law change in 2010 declared that a fielder could not jump from behind the boundary and, while airborne, parry the ball back on to the field.
Occasionally, there is an erroneous use of the term boundary as a synonym for a "four". For example, sometimes commentators say such as "There were seven boundaries and three sixes in the innings." The correct terminology would be "There were ten boundaries in the innings of which seven were fours and three were sixes."
When this happens the runs are automatically added to the batsman's and his team's score and the ball becomes dead. If the ball did not touch the bat or a hand holding the bat, four runs are scored as the relevant type of extra instead; six runs cannot be scored as extras, even if the ball clears the boundary, which is in any case extremely unlikely.
Any runs the batsmen completed by running before the ball reached the edge of the field do not count, unless they are greater than the number of runs that would be scored by the boundary, in which case it is the runs from the boundary that are discounted.
The scoring of a four or six by a good aggressive shot displays a certain amount of mastery by the batsman over the bowler, and is usually greeted by applause from the spectators. Fours resulting from an edged stroke, or from a shot that did not come off as the batsman intended, are considered bad luck to the bowler. As a batsman plays himself in and becomes more confident as his innings progresses, the proportion of his runs scored in boundaries often rises.
An average first-class match usually sees between 50 and 150 boundary fours. Sixes are less common, and usually fewer than 10 (and sometimes none) will be scored in the course of a match.
The Laws allow for captains to change the boundary allowances (number of runs scored through either type of boundary) through a pre-match agreement.
Four runs are scored as overthrows if a fielder gathers the ball and then throws it so that no other fielder can gather it before it reaches the boundary. In this case, the batsman who hit the ball scores however many runs the batsmen had run up to that time, plus four additional runs, and it is counted as a boundary. If the ball has not come off the bat or hand holding the bat, then the runs are classified as 'extras' and are added to the team's score but not to the score of any individual batsman.
Four runs (or more) can also be scored by hitting the ball into the outfield and running between the . Four runs scored in this way is referred to as an "all run four" and is not counted as a boundary.
Prior to 1910, six runs were only awarded for hits out of the ground, "Ask Steven", 23 January 2006 Retrieved 7 July 2011 with custom in Australia to award five runs for clearing the boundary.
Although official records for the longest six do not exist due to the difficulties of accurately measuring such distances, there is some evidence to show Australia’s Brett Lee struck a six 130–135 meters against West Indies in a Test match at the Gabba in 2005, although he used a carbon fibre–reinforced bat, which was later banned. a yellow seat marks the biggest six hit at the ground.]]
The record for the most sixes in a Test match is 37, which occurred during a 2019 Test match between India and South Africa in Visakhapatnam.
The record for most sixes in a One Day International is 46, which was achieved in a match between West Indies and England at St George's on 27 February 2019. The equivalent record in Twenty20 Internationals was set at Centurion Park, 35 sixes were hit during a match between South Africa and West Indies on 26 March 2023.
In 2012, during the First Test against Bangladesh in Dhaka, West Indies cricketer Chris Gayle became the first player to hit a six off the first ball in a Test cricket match.
