The game of `Squash` is not that much ancient compare to other famous sports. The history of Squash dates back to around 1830, when it was invented in Harrow School. The game has actually derived from the game named `Racquets`. No unique statement can be found about the origins of the game. The story of inventing the game is quite interesting. The students of the school found that if a punctured racket`s ball is `squashed` with the ball; it produces another game that has a greater variety of shots and also requires much more fitness and effort. This sudden invention of the students became quite popular within a very short span of time and encouraged the school management to construct the first four Squash courts in the school ground at 1864. The year 1864 is officially considered to be the founding year for Squash as a sport.

There was no international standardisation of rules and regulations for playing Squash in the initial period in the history of Squash. The people around the world used to play the game with slight variations in the rules and the equipments were also different in various parts of the world. Only two main methods or streams of the play were followed at that period. One method was being followed in England in which, the width of the court was 21 feet and the players used the `soft` balls to play. The other method was being followed in North America and according to this method, the width of the court was 18.5 feet and the players used `hard` balls to play the game. In this method, both the courts were of the same width of 32 feet. The universality of the Squash was not seriously challenged at that time, as well.

However, as there was no standard size for courts, the players from different places were facing some problems, while playing the game. To solve these problems, the Tennis and Rackets Association started a process in 1911 to finalise a standard size of the court. However, it took a long eleven years to finalise the measurement and in 1922, the Championships were started to be played, following the new measurement of courts. The standard court was finally been formalised only after the First World War was over. The rackets that were used at the early days were almost similar to those that are used today; however, the balls differed in a great way.

The initial days in the history of Squash saw the existence of only two associations namely the Squash Rackets Association of England and the United States Squash Rackets Association. These two associations were used to control the modern international Squash at that time. The first ever dedicated association to codify the game of Squash was formed in America in the year 1907. After that, the representatives of the sport from the countries like India, Australia, Great Britain, New Zealand, Pakistan, South Africa, USA, Canada and the United Arab Republic met in a world conference in London in 1966. All of them agreed that there is a need of founding an International body that would govern the game. According to the decision of the meeting, the International Squash Rackets Association (ISRF) was formed in 1966.

The first meeting of the International Squash Rackets Association (ISRF) as held on 5th January 1967, and in the meeting, the Federation decided that the game would be universally recognised simply as `Squash`, rather than `Squash Rackets`. The ISRF took a lot of initiatives to spread the game all over the world and soon it got connected with the Women`s International Squash Federation (WISF) in 1985. The members of the Federation unanimously decided to change its name to the World Squash Federation (WSF), in the year of 1992. At present, the WSF is the only International Federation for the sport and it bears responsibilities for the rules of the Game, Court and Equipment Specifications, Refereeing and Coaching. The WSF regularly maintains a World Calendar of events. It also organises and promotes World Championships for Men, Women, Junior Men, Junior women and Master at different age groups in both singles and doubles Squash.

Apart from promoting the game and organising different international tournaments, the World Squash Federation (WSF) has also standardised the size of the Squash court. The rules of WSF state about various kinds of court dimensions for different circumstances like `singles` or `doubles` games, and also in different regions of the world. The official court size for Squash singles matches is 9.75m (32 feet) in length, 6.4m (21 feet) in width and 4.57m (15 feet) in height at the front wall. The tin of the courts is required to be located at the base of the front wall and should reach 48cm (19 inches) in height.

The game has got a lot of popularity all over the world so far in the history of Squash. Its popularity is also increasing at a high speed in now-a-days. Squash is being played in a large number of 130 countries in the world and about 116 national associations have already become members of the World Squash Federation. The Member Nations of the Federation take several initiatives for the development of the sport and the Federation is also helping them in many ways. India`s neighbouring country, Pakistan is considered to be the greatest ever Squash playing nation in the history of Squash so far. Pakistan has also produced the highest number of World Champions in Squash, till now.
