Whether you’re setting up a badminton court in your backyard, trying to understand the rules better, or just curious about the exact measurements, understanding court dimensions is essential for every badminton player.
I remember my first time playing on a regulation court. I had been playing casually in my driveway for months, and when I stepped onto a proper court, everything felt different. The lines, the space, the net height—it all mattered more than I realized.
What confused me most? The different boundaries for singles and doubles. I kept hitting shots that I thought were “in,” only to realize I was using the wrong lines. It was embarrassing, but it taught me an important lesson: knowing your court is just as important as knowing how to hit the shuttle.
In this comprehensive guide, I’ll break down every measurement, every line, and every dimension you need to know about a badminton court. Whether you’re a beginner trying to understand the basics or someone planning to build a court, this guide has you covered.
Standard Badminton Court Dimensions: The Basics
A regulation badminton court is a precisely measured rectangle. Here are the fundamental dimensions:
Overall Court Dimensions:
- Length: 13.4 meters (44 feet)
- Width: 6.1 meters (20 feet)
- Total Area: 81.74 square meters (880 square feet)
These measurements are standard worldwide and are set by the Badminton World Federation (BWF). Whether you’re playing in Tokyo, London, or New York, the court dimensions remain the same.
Important Note: These are the outer boundary dimensions. The actual playing area differs between singles and doubles matches, which we’ll cover in detail below.
Singles Court vs Doubles Court: The Key Difference
This is where most beginners get confused. The badminton court has different boundary lines for singles and doubles play.
Singles Court Dimensions:
- Length: 13.4 meters (44 feet) – same as doubles
- Width: 5.18 meters (17 feet) – narrower than doubles
- Service Court Length: 3.96 meters (13 feet)
Doubles Court Dimensions:
- Length: 13.4 meters (44 feet) – same as singles
- Width: 6.1 meters (20 feet) – wider than singles
- Service Court Length: 3.05 meters (10 feet)
The Simple Rule:
- Doubles court is WIDER but has a SHORTER service court
- Singles court is NARROWER but has a LONGER service court
Think of it this way: in doubles, you have two players covering the court, so you need more width. But the service court is shorter to prevent easy ace serves. In singles, one player covers less width, but the service court extends deeper to make serving more strategic.
Understanding the Court Lines: What Each Line Means
A badminton court has several lines, each serving a specific purpose. Let’s break them down:
1. Outer Boundary Lines (Sidelines)
Function: Define the court’s outer limits
For Doubles:
- Use the outermost sidelines
- Full width of 6.1 meters (20 feet)
For Singles:
- Use the inner sidelines
- Narrower width of 5.18 meters (17 feet)
Common Mistake: In singles, hitting the shuttle beyond the inner sideline (but within the outer sideline) is OUT. Many beginners think the outer line counts in singles—it doesn’t.
2. Back Boundary Lines (Baselines)
Function: Mark the back limit of the court
Measurement: Same for both singles and doubles – 13.4 meters from net
Important: These lines are IN. If the shuttle lands on the line, it’s considered inside the court.
3. Short Service Line
Function: Marks the front limit of the service court
Distance from Net: 1.98 meters (6.5 feet)
Rule: In both singles and doubles, the serve must land beyond this line. Landing on or before it is a fault.
4. Long Service Line (Doubles Only)
Function: Marks the back limit of the doubles service court
Distance from Back Boundary: 0.76 meters (2.5 feet) from the back line
Critical Rule: In doubles, serves must land before this line. The area between this line and the back boundary is only used during rallies, not serves.
Singles Note: Singles matches do NOT use this line for serving. In singles, you can serve all the way to the back boundary line.
5. Center Line
Function: Divides the court into left and right service courts
Length: Runs from the short service line to the back boundary line
Usage: Determines which service court you serve into (right or left)
Width: Typically 40mm (1.5 inches) wide
Net Specifications: Height and Positioning
The net is arguably the most important feature of a badminton court. Here are the exact specifications:
Net Height:
- At the Center: 1.524 meters (5 feet exactly)
- At the Posts: 1.55 meters (5 feet 1 inch)
Why the difference? The net sags slightly in the middle due to gravity and tension. This 26mm (1 inch) difference is intentional and regulated.
Net Width:
- Minimum: 6.1 meters (20 feet) – spans the full court width
- Should extend 150mm (6 inches) beyond the sidelines on each side
Net Mesh:
- Small uniform mesh
- Dark color (typically black or dark green)
- Top edge should have 75mm (3 inches) white tape
Post Position:
- Posts are positioned on the doubles sidelines
- Distance between posts: 6.1 meters (20 feet)
- Posts should be sturdy and not obstruct players
Testing Net Height: Use a measuring stick or ruler to verify the center height. Many casual courts have nets that are too high or too low, which changes the game significantly.
Service Court Dimensions: Where You Must Serve
Service courts are critical because serves must land within these specific areas. The dimensions differ between singles and doubles.
Singles Service Court
Length:
- From short service line to back boundary line
- Distance: 3.96 meters (13 feet)
Width:
- From center line to inner sideline
- Distance: 2.59 meters (8.5 feet)
Total Singles Service Box Area:
- 10.26 square meters per side
Rule: The serve must travel diagonally from one service court to the opposite service court. It must clear the short service line and land before the back boundary, staying within the singles sidelines.
Doubles Service Court
Length:
- From short service line to long service line (NOT the back boundary)
- Distance: 3.05 meters (10 feet)
Width:
- From center line to outer sideline
- Distance: 3.05 meters (10 feet)
Total Doubles Service Box Area:
- 9.3 square meters per side
Rule: The doubles serve is shorter but wider. It must clear the short service line and land before the long service line, using the full width of the court.
Key Difference: Doubles service courts are actually SMALLER in total area than singles service courts, despite the court being wider overall. This prevents easy power serves in doubles.
Court Surface and Surrounding Space
Court Surface Requirements
Material:
- Wood flooring (most common for indoor courts)
- Synthetic mats (PVC or rubber)
- Concrete (for outdoor recreational courts)
- Acrylic surface (professional outdoor courts)
Color:
- Typically green or blue for the playing surface
- White or yellow lines for visibility
- Should have minimal glare
Characteristics:
- Non-slip surface
- Some shock absorption (protects joints)
- Even and level (no bumps or dips)
- Good traction for quick movements
Required Surrounding Space
According to BWF regulations, there must be clear space around the court:
For Recreational Play:
- Sides: Minimum 1 meter (3.3 feet)
- Ends: Minimum 2 meters (6.6 feet)
For Tournament/Competitive Play:
- Sides: Minimum 2 meters (6.6 feet)
- Ends: Minimum 2.5 meters (8.2 feet)
For International Competitions:
- Sides: Minimum 3 meters (10 feet)
- Ends: Minimum 4 meters (13 feet)
Ceiling Height:
- Minimum: 9 meters (30 feet) for international competitions
- Recreational: At least 7.5 meters (25 feet)
- Lower ceilings can interfere with high clears and serves
Why Space Matters
I once played in a gym with posts too close to the court. During an intense rally, I ran back for a clear and crashed into a post. It was painful and dangerous. Adequate space isn’t just a rule—it’s a safety requirement.
Line Markings: Colors, Widths, and Standards
Proper line markings are essential for fair play and clear visibility.
Line Width:
- Standard: 40mm (1.5 inches)
- All lines should be consistent width
- Lines are part of the court (IN)
Line Color:
- Most Common: White or yellow
- Should contrast clearly with court surface
- Must be visible under court lighting
Material:
- Painted directly onto surface (permanent courts)
- Tape for temporary courts (ensure it doesn’t peel or move)
- Should be flat, not raised (prevents tripping)
Line Configuration: For courts serving both singles and doubles, you’ll see multiple lines:
- Outer sidelines (doubles)
- Inner sidelines (singles)
- Back boundary (both)
- Short service line (both)
- Long service line (doubles only)
- Center line (both)
Pro Tip: When setting up a court, use different colors for singles and doubles lines if possible. For example, white for doubles boundaries and yellow for singles boundaries. This reduces confusion during play.
Converting Measurements: Meters to Feet
For those more comfortable with imperial measurements, here’s a complete conversion chart:
Court Dimensions:
- Length: 13.4m = 44 feet
- Doubles Width: 6.1m = 20 feet
- Singles Width: 5.18m = 17 feet
Service Courts:
- Short service line from net: 1.98m = 6.5 feet
- Singles service length: 3.96m = 13 feet
- Doubles service length: 3.05m = 10 feet
- Long service line from back: 0.76m = 2.5 feet
Net Height:
- At posts: 1.55m = 5 feet 1 inch
- At center: 1.524m = 5 feet exactly
Line Width:
- 40mm = 1.57 inches (approximately 1.5 inches)
How to Measure and Mark a Badminton Court
Planning to set up your own court? Here’s a step-by-step guide:
Step 1: Gather Your Tools
You’ll Need:
- Measuring tape (at least 15 meters/50 feet)
- Chalk or marking paint
- String line
- Stakes or markers
- Carpenter’s square (for right angles)
- Helper (makes measuring much easier)
Step 2: Mark the Outer Rectangle
Process:
- Find a flat, level area
- Mark one corner as your starting point
- Measure 13.4 meters (44 feet) for the length
- Mark the opposite corner
- Measure 6.1 meters (20 feet) for width
- Complete the rectangle
- Use the 3-4-5 triangle method to ensure 90-degree corners
Checking Square Corners:
- Measure diagonal distances
- Both diagonals should be exactly 14.723 meters (48.3 feet)
- If not equal, adjust corners until they are
Step 3: Mark the Net Line
Position:
- Exactly at the center of the court
- 6.7 meters (22 feet) from each back boundary
- Should be perfectly perpendicular to sidelines
Step 4: Mark Service Lines
Short Service Line:
- 1.98 meters (6.5 feet) from the net line
- Parallel to the net
Long Service Line (Doubles):
- 0.76 meters (2.5 feet) from the back boundary
- Parallel to back boundary
Step 5: Mark Center Line
Position:
- Runs from short service line to back boundary
- Exactly at the center (3.05 meters/10 feet from each sideline)
- Perpendicular to net line
Step 6: Mark Singles Sidelines
Position:
- 0.46 meters (1.5 feet) inside the doubles sidelines
- Runs full length of court
- Final singles width: 5.18 meters (17 feet)
Step 7: Verify All Measurements
Double-Check:
- All parallel lines are truly parallel
- All perpendicular lines form 90-degree angles
- Measure diagonals of all rectangles
- Net posts positioned correctly at 6.1 meters apart
Step 8: Paint or Tape Lines
Best Practices:
- Use line width of 40mm (1.5 inches)
- Ensure lines are straight and clean
- Let paint dry completely before playing
- If using tape, press firmly to prevent peeling
Common Court Dimension Mistakes to Avoid
Mistake 1: Using Wrong Sidelines in Singles
Problem: Players use the outer (doubles) sidelines during singles play
Consequence: Shots that are actually OUT are called IN
Solution: Before starting a singles match, verbally confirm which lines are in play. The inner sidelines are the boundaries in singles.
Mistake 2: Incorrect Net Height
Problem: Net is set too high or too low
Consequence: Changes the game dynamics—high nets favor low shots, low nets favor high shots
Solution: Measure the net at center (5 feet exactly) before every match. Adjust tension to achieve proper sag.
Mistake 3: Short Service Line Too Close
Problem: Short service line marked closer than 1.98 meters
Consequence: Makes serving too easy, reduces rally length
Solution: Always measure from the center of the net line to verify correct distance.
Mistake 4: Forgetting the Long Service Line in Doubles
Problem: Not marking the doubles long service line
Consequence: Serves that should be faults are called good
Solution: Clearly mark the long service line 0.76 meters from the back boundary.
Mistake 5: Uneven Court Surface
Problem: Court has bumps, dips, or slopes
Consequence: Shuttle bounces unpredictably, increases injury risk
Solution: Check surface level before marking lines. Use a level or water test to identify problem areas.
