Squash Court Dimensions Calculator for Fast Spec Checks
🎾 Squash Court Dimensions Calculator
Measure court length, width, wall heights, and clear height with standard singles and doubles targets.
Use this calculator to compare a real court layout against the WSF-style singles, doubles, and international doubles dimensions. It checks footprint, diagonal, wall envelope, and clearance in one pass.

🎯 Quick Spec Grid
Standard singles target
Use 9.75 m length, 6.40 m width, a 4.57 m front-wall line, and 5.64 m clear height for the benchmark view.
International doubles target
Keep the same length, expand width to 8.42 m for event play, and drop the tin to 33 cm where the event standard allows it.
💡 Practical Tips
Measure the plan height
Take length and width at 1000 mm above the floor so the numbers line up with the WSF plan method.
Watch the ceiling first
If the clear height falls short, the room stops being a court even when the floor plan is perfect.
To ensure that a game of squash functions correctly on a squash court, the squash court must adhere to specific dimension. If the dimensions of a squash court are incorrect, the game of squash wont play correctly on that squash court. For example, if the width of the squash court is too narrow for squash court play, then the rallies that occur in that squash court will be pinned against the courts sidelines.
Conversely, if the squash court is too wide, the players will often allow the ball to float off of the squash courts playing surface, thus slowing the game of squash. The length of the squash court must be nine and three-quarters meter from the front wall to the back wall of the squash court. This specific length is used for squash court play because it allows the players to drive the ball, volley the ball, and retrieve the ball from the court without having to waste any step.
Squash Court Measurements
However, the width of the squash court is different depending on whether the squash court is for singles or doubles play. Squash courts that is used for singles play are six point four meters in width. Squash courts that are used for doubles play are seven point six or eight point four meters in width.
The squash court for doubles play is more wider to allow for two pair of players to play on the court without colliding with each other. The height of the squash court must be five point six four meters minimum. Squash courts that have a height of less than five point six four meters will cause players to hit the ball into the ceiling of the squash court.
If a player hits the squash courts ceiling, that player risks making an injury to that players head or the game may result in a let call for that player. The squash court also features a metal strip at the bottom of the front wall of the squash court. This metal strip is referred to as the tin, and it dictates the bounce of the ball if it hits the ground near the front wall of the squash court.
The standard height for the tin is forty-eight centimeter for club play. However, for professional play of doubles squash, the tin height is thirty-three centimeters. If the height of the tin is lowered, the game will be played at a faster rate because dying shots will die more quick on the squash court.
Squash courts also feature several line on the court to define the boundaries of the squash court. The front wall line of the squash court is four point five seven meters from the ground to the front wall. This line marks the out boundary of the squash court.
The back wall line is two point one three meters from the ground to the back wall of the squash court. The service line is located one point seven eight meters from the ground to the squash court floor. This line divides serves from drives on the squash court.
The short line is located four point two six meters from the back wall. This line divides the squash court into a front zone and a rear zone of the squash court. These lines on the squash court must be fifty millimeter wide.
Additionally, the lines must be crisp so that players are clear about the boundaries of the squash court. Due to the various specifications of a squash court, the construction of a squash court can become complicated. Some squash courts use glass for their back walls so that spectators can view the squash game.
However, using glass for the back wall can reduce the width of the squash court. Additionally, for doubles squash courts, the service boxes must be one point six meter square on each side of the squash court. This is because doubles squash courts require two players on each side of the squash court.
Therefore, the design of the squash court must account for each player landing after serving the squash ball. Furthermore, the diagonal measurement of a squash court is approximately eleven and a half meters from one corner of the squash court to the opposite corner of the squash court. The diagonal measurement can reveal issues with the flatness of the squash courts floor or the squareness of the squash court itself.
When measuring a squash court, specific procedures must be followed to ensure that no error are made in measuring the squash court. The width of the squash court should be measured at a height of one meter above the squash courts floor. This is because squash court walls may taper and the court floor may be higher than the squash courts back lines at floor level.
Additionally, the temperature of the squash court should be considered when measuring the squash court. Squash courts that are hotter will cause the squash ball to travel at a faster rate. Therefore, squash courts that are particularly hot may require more clear height for squash players to reach the balls that are driven at the players.
Additionally, squash courts that are colder will cause the squash ball to bounce less on the squash court floor. Therefore, squash courts that are cold may permit errors made with the squash courts tin. Finally, another way to determine whether a squash court is suitable for use in a squash tournament is to use a fit score for the squash court.
The length of the squash court and the width of the squash court are each weighted at twenty percent in the fit score. These two dimension are the non-negotiable dimensions for squash play. The ceiling height of the squash court and the height of the tin of the squash court are also accounted for in the fit score.
If the fit score of the squash court is ninety or higher, then the squash court is ready to host a squash tournament. However, if the score of the squash court is below seventy, then the retrofit of the squash court should of been thought through more carefuly.
