Badminton Court Size Calculator
Badminton court dims, area, and net heights.
What it does
Badminton courts pack big rallies into small rectangles. Doubles spans 13.40 by 6.10 meters with singles sidelines 0.46 m inside each side, short service 1.98 m from the net, and a net sagging from 1.55 m posts to exactly 5 ft at center. Every line has a number.
The tool above prints regulation dims, area, and net heights for either game in feet or meters. Doubles gives 43.96 x 20.01 ft over 880 sq ft; singles gives 43.96 x 16.99 ft over 747. Metric mirrors read 13.4 x 6.1 and 13.4 x 5.18.
USA Badminton publishes the BWF-aligned rules with court diagrams, linking the BWF Laws statutes behind each figure. The federation path runs USAB to BWF to the Laws text with identical dims: 13.40, 6.10, 5.18, 1.55, 1.524, 1.98, and 0.72 meters.
Service lines shape each rally. Short service keeps serves deep while the doubles long-service line 0.72 m from the back punishes floaters, and singles alleys vanish from play. Build to the lines first; clearance and mats follow hall guides.
