Tennis Court Dimensions & Badminton Court Size: The Complete Technical Guide for Facility Planners

When planning a sports facility, getting court dimensions exactly right is not optional. Even a few centimetres off the official specification can affect gameplay, fail inspection, and invalidate a facility for competitive use. Whether you are designing a new build, retrofitting an existing space, or simply trying to understand the standards, this guide covers everything you need to know about official tennis and badminton court dimensions — and the practical considerations that come with them.

Part One: Tennis Court Dimensions

Official ITF Measurements

The International Tennis Federation (ITF) sets the globally recognised standards for tennis court dimensions. These apply to all levels of play, from recreational club courts to Grand Slam venues.

Full Court (Doubles)

Length: 23.77 metres (78 feet)

Width: 10.97 metres (36 feet)

Singles Court

Length: 23.77 metres (78 feet — same as doubles)

Width: 8.23 metres (27 feet)

The difference between singles and doubles width is created by the addition of the doubles alleys, each measuring 1.37 metres (4.5 feet) on either side of the singles court.

Runoff and Clearance Zones The playable court area is only part of the total land requirement. The ITF recommends the following minimum runoff space around the court:

Behind each baseline: 6.40 metres minimum (international competition standard)

On each side: 3.66 metres minimum

For recreational or club play, behind baselines can reduce to 5.49 metres

This means the total recommended land area for a single tennis court is approximately 36.57 metres x 18.29 metres — roughly 669 square metres.

Overhead Clearance For indoor courts or covered facilities, the ITF recommends a minimum clear height of 9.14 metres (30 feet) above the court surface for competitive play. Recreational facilities can work with slightly lower clearances but should aim for a minimum of 7–8 metres.

Multi-Court Planning

When planning multiple tennis courts side by side, the shared runoff between adjacent courts is typically reduced. The standard approach:

Between two courts (shared side boundary): 3.66 metres shared space (1.83 metres per court)

For a bank of four courts: approximately 42 metres wide total footprint

Always confirm local planning and sports governing body requirements before reducing runoff below recommended minimums.

Net Post Positioning

Net posts are positioned 0.914 metres outside each side of the doubles court. This is a commonly overlooked detail in facility planning — the posts must be accounted for in the total width calculation and their foundation requirements included in the groundworks specification.

Part Two: Badminton Court Dimensions

Official BWF Measurements

The Badminton World Federation (BWF) is the governing body that sets international court standards for badminton.

Full Court (Doubles)

Length: 13.40 metres (43 feet 11 inches)

Width: 6.10 metres (20 feet)

Singles Court

Length: 13.40 metres (same as doubles)

Width: 5.18 metres (17 feet)

Unlike tennis, where the singles and doubles courts share the same length, badminton has a subtle but important dimensional difference. In doubles play, the full width is used but the service court is shorter — the long service line for doubles sits 0.76 metres inside the back boundary line. In singles, the full length is used but the court is narrower.

Runoff and Clearance Zones Badminton is a fast-moving sport with significant shuttle flight paths, making adequate clearance zones essential for both safety and fair play.

Behind each back boundary line: minimum 1.0 metre (recreational); 2.0 metres recommended for competition

On each side: minimum 1.0 metre; 1.5 metres recommended

This gives a total recommended playing area of approximately 17.40 metres x 9.10 metres per court — roughly 158 square metres, significantly more compact than tennis.

Overhead Clearance This is where badminton has its most demanding requirement. The BWF specifies a minimum overhead clearance of 12 metres above the court surface for international competition. For club and recreational play, a minimum of 9 metres is widely accepted, though higher is always preferable given the shuttle's flight arc on high clears and smashes.

This clearance requirement is the single biggest constraint in indoor badminton facility planning and must be carefully evaluated before committing to a venue or building specification.

Multi-Court Planning

Badminton courts are compact enough that multiple courts can be installed in relatively modest indoor halls. Standard planning configurations:

A standard sports hall of 32m x 18m can accommodate 4 badminton courts side by side with compliant runoffs

A larger hall of 40m x 20m can accommodate 6 courts in a two-row layout

Divider curtains between adjacent courts are strongly recommended to prevent shuttle drift interference during play

Part Four: Practical Considerations for Facility Planners

Dual-Use Court Design Many facilities are now exploring dual-use court layouts, where a single space can be used for both tennis and badminton by applying both sets of line markings in contrasting colours. This is technically feasible but requires careful line colour selection to avoid confusion during play. ITF and BWF guidelines both allow for multi-line courts provided different line colours are used for each sport.

Line Marking Colour Conventions A common approach for dual-use courts:

Tennis lines: white

Badminton lines: yellow or blue

All lines should be 40mm wide per both governing body standards

Surface Compatibility Tennis and badminton have different surface requirements. Tennis is commonly played on acrylic hard courts, clay, or grass outdoors. Badminton demands a non-slip indoor surface — typically sprung hardwood, PVC sports flooring, or synthetic rubber. Dual-sport facilities must choose a surface that safely accommodates both, which is why high-quality synthetic sports flooring with appropriate grip and cushion ratings is the preferred solution for multi-use indoor venues.

Lighting Standards Adequate lighting is critical for both sports, particularly given the speed of play involved.

Tennis (recreational): minimum 300 lux at court level

Tennis (competition): 500–750 lux or higher for broadcast

Badminton (recreational): minimum 300 lux

Badminton (competition): 500–750 lux; high-speed shuttle tracking requires even light distribution with minimal glare

LED sports lighting systems are now the standard specification for new facilities, offering superior uniformity, energy efficiency, and long service life compared to traditional metal halide systems.

Final Thoughts

Whether you are planning a single community court or a multi-sport facility, precision in court dimensions is the foundation everything else is built on. Get the measurements right, account for the full runoff and clearance requirements — not just the playing area — and ensure your surface, lighting, and line marking specifications comply with ITF and BWF standards from the outset.

Cutting corners on court dimensions is a false economy. The cost of remediation or rejection at inspection far exceeds the investment in getting the specification right from the start.
