Hardball squash is a format of the indoor racquet sport squash which was first developed in North America in the late 19th century and early 20th century. It is sometimes referred to as being the "American version" of the sport. The one significant difference between hardball squash and regular squash, as evident for its name is that, the hardball game is played using a harder rubber ball which plays faster, and usually on a smaller court for singles play, or a much larger court for the doubles game.
Records of squash being played in Canada go back to the early 1880s. There it was found that the softer squash balls being used in Britain were not ideally suited to playing in the extremely cold conditions of the Canadian winter, and so a harder rubber ball was developed. It was quickly discovered that this ball was better suited to playing on slightly narrower courts than were used in the British version of the game. As the popularity of the game spread around Canada, the United States and Mexico, court specifications were codified. By 1929, official court plans were being sold by the United States Squash Racquets Association (USSRA) (now called U.S. Squash), and the hardball game was brought into controlled growth.
Though hardball squash is no longer a very popular game for singles play, the hardball doubles game continues to thrive. Hardball doubles is played on a court measuring 45 ft long (14 m) and 25 ft wide (7.6 m). The game which was popular in North America in the past has considerably lost it appeal and has been replaced by regular squash. But there seems to still be some interest in the doubles version of the sport.
