Setting up or marking a playing area requires precise measurements. A standard badminton court is 13.4 meters long and 6.1 meters wide for doubles matches, while singles matches narrow the playing width to 5.18 meters. Understanding these official dimensions ensures compliance with tournament standards and prevents spacing issues in backyard or indoor installations.
According to the Badminton World Federation, the governing body sets rigorous specifications for every line, post, and net height. Whether you're planning a community center gym or laying down court tape in a gymnasium, getting the geometry right changes how the shuttlecock travels and how players move across the surface.
Official Dimensions for Singles and Doubles
The boundary lines change depending on whether one player competes against another or teams face off in pairs. The length remains constant at 13.4 meters (44 feet) for both formats, but the width shifts significantly.
- Doubles Width: 6.1 meters (20 feet) wide, utilizing the outer side lines.
- Singles Width: 5.18 meters (17 feet) wide, utilizing the inner side lines.
- Total Length: 13.4 meters (44 feet) from the back baseline to the back baseline.
The short service line sits 1.98 meters (6 feet 6 inches) away from the net line. This creates the front service court where serves must land during gameplay. The center line divides each service court down the middle, separating the left and right service zones.
Net Height and Post Placement
The net stands at the exact center of the 13.4-meter length, splitting the playing surface into two equal halves of 6.7 meters.
- Net Height at Posts: 1.55 meters (5 feet 1 inch) high at the outer sidelines.
- Net Height at Center: 1.524 meters (5 feet) high directly in the middle where the net sags slightly under its own tension.
- Post Position: Posts stand on the doubles sideline regardless of whether singles or doubles is played. This means singles players must navigate posts positioned slightly outside their actual playing boundaries.
The net itself measures 760 millimeters in depth and must be made of fine dark-colored cord of even thickness with a mesh between 15 and 20 millimeters.
Clearance and Overhead Space Requirements
A common mistake during court construction is failing to account for surrounding clearance space. Players require safe run-off areas beyond the baseline and sidelines to prevent collisions with walls or equipment.
- Side Clearance: At least 0.5 to 1 meter of clear space around the sidelines.
- Baseline Clearance: At least 1.5 to 2 meters behind the baselines for defensive retrievals.
- Ceiling Height: Official international competition venues require a minimum ceiling height of 9 meters (29.5 feet) free from obstructions like beams, lights, or HVAC units. Recreational spaces should aim for at least 7 meters to accommodate high lifts and clears.
Common Layout Mistakes to Avoid
Laying out a court incorrectly ruins the flow of the game and causes disputes during matches. Here are frequent errors to watch out for:
- Using singles width for doubles: Forgetting that doubles uses the outer tramlines alters the court area by nearly a meter.
- Ignoring flooring friction: Slippery wooden floors or uneven concrete lead to ankle injuries. High-impact vinyl or specialized wooden sports flooring with proper grip is essential.
- Incorrect line thickness: Official lines should be 40 millimeters wide, typically painted in white or yellow for high contrast against the floor. Lines form part of the measurement, so they must be measured from the outside edge of the line.
Frequently Asked Questions
What is the diagonal measurement of a standard badminton court?
For a full doubles court measuring 13.4 meters by 6.1 meters, the diagonal from corner to corner is approximately 14.72 meters (48 feet 3 inches). Measuring diagonals is the easiest way to ensure the court is completely square during setup.
Can you play singles on a doubles court?
Yes. During singles play, players use the inner sidelines for width boundaries, but they still use the very back baseline for length. The service rules also change, as singles serves must reach the back service line instead of the shorter doubles service line.
How much space is needed for a backyard badminton setup?
You need an absolute minimum area of 16 meters by 8 meters to accommodate the court plus the necessary safety clearance around all four sides.
Why is the net lower in the middle than at the posts?
The net is pulled taut at the posts to 1.55 meters, but gravity causes a slight natural dip in the center down to 1.524 meters. This standardized drop ensures consistent clearance rules across international play.
