A standard singles squash court is 9.75 m long and 6.40 m wide (32 ft x 21 ft), giving a 62.4 sq m playing floor. The front wall carries an out-line 4.57 m high, a service line at 1.78 m and a tin (the lower out-of-court limit) at 0.48 m, while the back wall out-line is 2.13 m and the total height clearance above the court is 5.64 m. These are the official squash court dimensions defined by the World Squash Federation, and they apply to club, school and tournament courts alike. The guide below sets out every measurement, the court layout and markings, the space and clearances a building needs, and how a regulation court is constructed in India.
Official squash court dimensions and measurements
A squash court is a sealed, four-wall room rather than an open marked-out field, so its dimensions describe both the floor and the heights of the lines on the front, side and back walls. The singles court that is used for almost all recreational, school and competitive play in India measures 9.75 m from front wall to back wall and 6.40 m from side wall to side wall. In imperial units that is 32 feet by 21 feet, a floor area of 62.4 square metres.
The front wall is the busiest surface. Three horizontal lines run across it: the tin at the bottom, the service line in the middle and the out-line at the top. The two side walls slope down from the front-wall out-line (4.57 m) to the back-wall out-line (2.13 m), and the back wall on a show court is made of toughened glass so spectators can watch. Every line on a regulation court is 50 mm (5 cm) wide and, traditionally, red.
Singles squash court measurements table
The table below lists the official squash court dimensions for a singles court, with metric and imperial values for the key measurements.
| Measurement | Metric | Imperial (approx.) |
| Court length (front wall to back wall) | 9.75 m | 32 ft |
| Court width (side wall to side wall) | 6.40 m | 21 ft |
| Playing floor area | 62.4 sq m | 672 sq ft |
| Front wall out-line height | 4.57 m | 15 ft |
| Front wall service line height | 1.78 m | 6 ft |
| Tin height (lower out limit, standard) | 0.48 m | 19 in |
| Tin height (professional play) | 0.43 m | 17 in |
| Back wall out-line height | 2.13 m | 7 ft |
| Service box (each, square) | 1.6 m x 1.6 m | 5.25 ft x 5.25 ft |
| Short line from front wall | 5.49 m | 18 ft |
| Total height clearance above court | 5.64 m | 18.5 ft |
Front wall lines: out-line, service line and tin
The front-wall out-line is set 4.57 m above the floor and marks the top boundary; any ball that strikes the wall above it is out. The service line sits at 1.78 m and only matters on the serve: a legal serve must hit the front wall above the service line and below the out-line. The tin is the strip of solid material along the bottom of the front wall whose upper edge is 0.48 m above the floor for standard play, dropped to 0.43 m for professional events to make rallies faster. Because the tin makes an audible "tin" sound when struck, players instantly know a shot has gone down. The tin is the squash equivalent of a tennis net or a badminton net: it is the lower limit a shot must clear.
Back wall and side wall lines
The back-wall out-line is 2.13 m above the floor. The two side-wall out-lines are diagonal: each runs in a straight line from the 4.57 m front-wall out-line down to the 2.13 m back-wall out-line, so the playable wall area tapers toward the rear of the court. On glass-back show courts the back wall and sometimes the side walls are toughened glass; on a standard club court they are rendered plaster or prefabricated squash panels. All of these line heights are fixed by the World Squash Federation court specifications, so a court built to them will play correctly anywhere in the world.
Squash court layout and floor markings
While the front wall carries the height lines, the floor of a squash court carries the lines that govern serving and the start of each rally. There are only three floor lines, and together with the front-wall lines they define the entire court.
The short line, half-court line and service boxes
The short line runs straight across the full width of the court, parallel to the front wall and 5.49 m back from it. It divides the court into a front half and a back half. The half-court line runs from the middle of the short line to the back wall, splitting the back half into two equal quarters. In the back corners of the court, against the side walls, sit the two service boxes (also called quarter-court boxes). Each box is a 1.6 m x 1.6 m square. The server stands with at least one foot inside a box, and after the serve the ball must land in the opposite back quarter.
Parts of a squash court at a glance
- Front wall: 6.40 m wide, carries the tin (0.48 m), service line (1.78 m) and out-line (4.57 m).
- Back wall: 6.40 m wide, out-line at 2.13 m, usually glass on a show court.
- Side walls: 9.75 m long, diagonal out-lines tapering from 4.57 m to 2.13 m.
- Floor: 9.75 m x 6.40 m sprung hardwood, with the short line, half-court line and two service boxes.
- Tin: the solid band along the foot of the front wall, the lower limit every shot must clear.
Line width and colour
All court lines, on both the walls and the floor, are 50 mm (5 cm) wide. They are conventionally red so they read clearly against a pale plaster wall and a light hardwood floor. Only the lines listed above are marked; a squash court has no centre service mark, no tramlines and no zones beyond the service boxes, which makes it one of the simplest courts to set out accurately.
Required total space and clearances
Because squash is played inside a sealed room, the "total space" for a court is really the internal volume of the building shell rather than a run-off margin around an open field. The walls of the court are the boundary, so a planner has to provide the floor footprint plus the full playing height with nothing intruding into it.
Footprint and height
The minimum internal footprint is the 9.75 m x 6.40 m playing area. The single most overlooked figure is the total height clearance of 5.64 m: lights, beams, ducting, sprinkler heads and the underside of the roof structure must all sit above this line, because a ball lobbed high off the front wall genuinely reaches it. For a glass-back show court, allow additional depth behind the back wall for the raised spectator gallery and for the structural frame that carries the glass.
Building services
A regulation court also needs even, glare-free lighting from above (so the white walls and the ball stay clearly visible), mechanical ventilation or air-conditioning to keep the sealed room cool and dry, and an access door set flush into the back wall so it does not interfere with play. In Indian conditions, ventilation and dehumidification matter as much as the court markings: a humid court makes the ball skid and the floor slippery.
How a squash court compares to related courts
Squash courts are compact and tall, which is the opposite of most racket and team sports played on a flat, open surface. The contrast below puts the singles squash court next to the doubles squash court and other ChampCourts surfaces.
| Court | Length | Width | Notes |
| Squash, singles | 9.75 m | 6.40 m | Enclosed four-wall room, 5.64 m height |
| Squash, doubles | 13.72 m | 7.62 m | Larger room, higher tin, rare in India |
| Badminton, singles/doubles | 13.4 m | 6.1 m | Open marked floor with a net |
| Tennis | 23.77 m | 10.97 m (doubles) | Open court, far larger footprint |
The key takeaway is that a singles squash court fits inside a surprisingly small floor plan, about the size of two badminton service halves, but it demands a tall, fully enclosed, climate-controlled room that those other sports do not. That is why a squash court is almost always built as a dedicated indoor structure rather than retro-fitted onto an existing open hall.
Surface and construction for squash courts in India
Getting the dimensions right is only half the job; the surfaces have to perform to the same standard the World Squash Federation sets for the court to play correctly. A regulation court combines a sprung hardwood floor with smooth, true walls, and ChampCourts builds both as a single turnkey package for clubs, schools, resorts and residential projects across India.
Sprung hardwood floor
The floor is the heart of a squash court. A regulation surface is a sprung tongue-and-groove hardwood floor, typically maple or beech, laid over a battened sub-frame so it gives a controlled, even spring underfoot and a true, fast roll for the ball. ChampCourts supplies and installs this system as its squash court hardwood flooring, sealed with the matt finish World Squash specifies so the white ball stays visible and the surface never becomes slippery. The same engineered timber expertise sits behind the wider ChampCourts hardwood sports flooring range used for indoor multi-sport halls.
Walls and back wall
The front and side walls must be dead-flat and rebound the ball predictably. Two systems are used: traditional rendered plaster walls finished in court-white, or modern prefabricated squash panels that bolt together for a faster, more consistent build. On a show court the back wall (and sometimes the side walls) is toughened glass on a steel frame, turning the court into a viewing arena. ChampCourts specifies the wall system to match the budget and use: panels and glass for a flagship club court, rendered plaster for a cost-effective school or society court.
Choosing the right build
The wall finish, the floor build-up and whether you want a glass back wall all move the cost and the playing feel. If you are weighing options across sports and surfaces, the ChampCourts which surface guide walks through the trade-offs so the specification matches how the court will actually be used, whether that is daily club play, a school sports programme or an amenity for an apartment complex.
Indoor vs outdoor squash courts
Squash is an indoor sport by definition. The four walls are part of the field of play, the ball is dark and needs controlled lighting to stay visible, and the 5.64 m height and sealed environment cannot be reproduced reliably in the open. There is no recognised outdoor regulation squash court the way there is for tennis or basketball.
In Indian conditions the case for building indoors is even stronger. Direct sun, dust, and the monsoon would all degrade a hardwood floor and rendered walls quickly, and heat and humidity make the ball behave inconsistently. Every competition and club court in the country is therefore housed inside a weatherproof, ventilated hall, and ChampCourts builds the court within exactly that kind of controlled, enclosed envelope.
Cost note for a squash court in India (2026)
As a 2026 planning guideline, a single regulation squash court in India typically costs from about Rs 18 lakh to Rs 35 lakh. The main variables are the wall system (rendered plaster at the lower end, prefabricated panels and a glass back wall at the upper end), the sprung hardwood floor specification, the lighting, and the ventilation or air-conditioning needed to keep the sealed room cool and dry. A flagship panel-and-glass show court sits at the top of that range, while a plaster-walled club or school court is more economical. Because the figure depends heavily on the site, ChampCourts provides an itemised estimate after a short survey rather than a flat rate.

FAQs about squash court dimensions and construction
What are the official squash court dimensions?
A standard singles squash court is 9.75 m long and 6.40 m wide (32 ft by 21 ft), giving a playing floor of 62.4 sq m. The front wall carries an out-line at 4.57 m, a service line at 1.78 m and a tin whose upper edge sits 0.48 m above the floor (0.43 m for professional events). The back wall out-line is 2.13 m, and the total clear height above the court is 5.64 m. These are the World Squash Federation specifications used for club, school and tournament courts worldwide.
How much space do you need to build a squash court?
The court itself occupies 9.75 m x 6.40 m (62.4 sq m) of floor, but the building must also allow for the 5.64 m total height clearance and for the rear wall, which is glass on a show court. In practice an enclosed single court needs an internal shell of roughly 10 m x 6.6 m with at least 5.64 m of unobstructed height. Plan extra room for the access door, the spectator gallery behind the back wall and the ventilation or air-handling units a sealed indoor court requires.
What is the height of the tin and the service line on a squash court?
On the front wall the tin (the 'out' band along the bottom, equivalent to a net) has its upper edge 0.48 m above the floor for standard play and 0.43 m for professional play. The service line on the front wall is 1.78 m high, and the front-wall out-line is 4.57 m high. A serve must strike the front wall between the service line and the out-line to be legal.
What size are the service boxes on a squash court?
Each service box (quarter court) is a square measuring 1.6 m x 1.6 m, set in the back corners of the court behind the short line. The short line runs across the court 5.49 m from the front wall, and the half-court line divides the back half into the two service boxes. The server must keep at least one foot inside the box when serving.
What is the difference between a singles and a doubles squash court?
A singles squash court is 9.75 m long x 6.40 m wide. A doubles court is significantly larger at 13.72 m long x 7.62 m wide, with a higher tin, to give two players per side room to move. Doubles courts are rare in India; almost every court built for clubs, schools and apartments here is the singles size, which is also the format used for the Asian Games and Olympic competition.
Can a squash court be built outdoors in India?
Squash is an indoor sport. A regulation court is a fully enclosed four-wall room with a sprung hardwood floor and plaster or panel walls, so it is built inside a weatherproof hall, not in the open. The 5.64 m height, sealed walls and controlled lighting cannot be reproduced reliably outdoors in Indian heat, dust and monsoon conditions, which is why every competition court is indoors.
What flooring is used on a squash court?
Regulation squash courts use a sprung tongue-and-groove hardwood floor, typically maple or beech, laid over a battened sub-frame that gives controlled shock absorption and a true, fast roll. ChampCourts supplies and installs this system through its squash court hardwood flooring, finished with the matt seal that World Squash specifies so the ball stays visible and the surface is not slippery.
How much does it cost to build a squash court in India in 2026?
As a 2026 guideline, a single regulation squash court in India typically costs from about Rs 18 lakh to Rs 35 lakh, depending on the wall system (plaster vs prefabricated panels), the sprung hardwood floor, a glass back wall, lighting and ventilation. A panel-and-glass show court sits at the upper end. ChampCourts provides an itemised, site-specific estimate after a quick survey; call +91 92587 75187 for a quote.
