Multi-purpose indoor and outdoor courts are common in schools, community centers, and sports complexes. To maximize space, several sports are often marked on a single playing surface. The challenge lies in ensuring that each sport’s lines are clearly distinguishable while minimizing visual clutter.
This article outlines the official court dimensions, recommended line colors, and practical design considerations for Basketball, Volleyball, Badminton, and Netball courts. 1. General Principles for Multi-Sport Court Design
When marking multiple sports on a single surface:

• Avoid visual confusion – use distinct colors for each sport’s lines.
• Prioritize primary sports – make the most frequently played sport’s lines more prominent.
• Consistent line thickness – usually 50 mm (2 inches) for most sports, except for badminton which uses 40 mm (1.57 inches).
• Durable paint – use high-contrast, non-slip polyurethane or epoxy-based line marking paint.
• Symmetry & positioning – align courts so that overlapping lines cause minimal interference.
• Lighting and flooring contrast – ensure court colors complement the surface color for maximum visibility.

2. Official Dimensions and Line Colors for Each Sport
A. Basketball Court

• Dimensions:
  • International (FIBA): 28.0 m x 15.0 m (91’10” x 49’2”)
  • Free-throw line: 4.6 m (15 ft) from backboard
  • 3-point line radius: 6.75 m (22’2”)
• Line Thickness: 50 mm (2 inches)
• Recommended Line Color: White (most common for clarity and priority)
• Notes for Multi-Sport Layout:
  • Basketball often serves as the primary sport in a multi-purpose hall; its lines should be the most visible.
  • Center circle and key areas should be clearly marked, avoiding confusion with other sports’ markings.

B. Volleyball Court

• Dimensions:
  • Court size: 18.0 m x 9.0 m
  • Attack line: 3.0 m from the center line
• Line Thickness: 50 mm
• Recommended Line Color: Red or Orange
• Notes:
  • Volleyball courts are centered within the basketball court space.
  • Use a color that contrasts both the basketball lines and flooring.

C. Badminton Court

• Dimensions:
  • Singles: 13.40 m x 5.18 m
  • Doubles: 13.40 m x 6.10 m
  • Short service line: 1.98 m from the net
• Line Thickness: 40 mm
• Recommended Line Color: Yellow (commonly used for easy distinction)
• Notes:
  • Badminton courts are smaller and may fit multiple times within a basketball court area.
  • Align parallel to basketball sidelines to maximize space usage.

D. Netball Court

• Dimensions:
  • Court size: 30.5 m x 15.25 m
  • Goal circle radius: 4.9 m
• Line Thickness: 50 mm
• Recommended Line Color: Green or Blue
• Notes:
  • Netball courts are similar in width to basketball but longer.
  • Goal circles should be clearly marked to avoid confusion with basketball’s key.

3. Example Color Allocation for Multi-Sport Court

Sport	Recommended Color	Line Thickness
Basketball	White	50 mm
Volleyball	Red/Orange	50 mm
Badminton	Yellow	40 mm
Netball	Green/Blue	50 mm

4. Design Tips for Multi-Sport Court Marking

1. Layer logically – Primary sport lines should be the brightest and least interrupted.
2. Use contrasting colors – Avoid colors that are too similar (e.g., yellow and light green) on light flooring.
3. Plan for overlap – In some cases, lines may share boundaries (e.g., outer volleyball and badminton lines).
4. Consider future sports – Leave space for adding more sports without repainting the entire floor.
5. Maintenance – Over time, repaint faded lines to maintain clarity.

• Volleyball: FIVB Official Volleyball Rules
• Badminton: BWF Laws of Badminton

Conclusion
Designing a multi-sport court requires precision, compliance with sport regulations, and thoughtful color planning. By allocating distinct colors for each sport—White for Basketball, Red/Orange for Volleyball, Yellow for Badminton, Green/Blue for Netball—players can easily identify the correct boundaries, enhancing both gameplay and safety.
A well-designed court not only supports multiple sports but also improves usability, reduces confusion, and maximizes facility value.
