North American vs International Squash Courts

North American Squash Courts are typically 2 feet narrower than International Courts. This was done during a time when low temperatures made it difficult to warm up a single or double dot squash ball, so a hard ball was used instead.

As the hard ball is bouncier and faster, players found it more manageable to play in narrower courts. However, as central heating systems came mainstream, it the soft ball became more playable and International size courts are preferred by more players and clubs.

Today, the hard ball squash court is more than 3 feet wider than the international court.
