Badminton Court Rules

Singles badminton court rules define a narrower playing area than doubles, a serving zone that stretches to the back wall, and a serving position that shifts with the score. Every point in a one-on-one match depends on these boundaries, so a clear picture of the lines saves you from silly disputes on court. This guide breaks down the official Badminton World Federation (BWF) court rules in plain language, with tables, a line-by-line diagram, and the 2026 updates that Indian players need to know. Singles Badminton Court Rules in One Line In singles badminton, players use the inner side lines (5.18 m wide) and the full back boundary line (13.4 m long) as playing limits, and the serve must land diagonally within the service court formed by the short service line, the center line, and the back boundary line. That single sentence covers the core of singles play. The sections below unpack every measurement, line, and rule so you can apply them confidently, whether you are marking a court at home or umpiring a club match. Singles Badminton Court Dimensions (Official 2026 Measurements) The BWF Laws of Badminton set one universal court size for both singles and doubles. Singles play simply ignores the two outer strips on either side. Here are the exact figures used in every BWF-recognised and Badminton Association of India (BAI) tournament today. Court Element Metric Imperial Total court length 13.4 m 44 ft Singles court width 5.18 m 17 ft Doubles court width (for reference) 6.1 m 20 ft Net height at the posts 1.55 m 5 ft 1 in Net height at the center 1.524 m 5 ft Short service line from net 1.98 m 6 ft 6 in Doubles long service line from back boundary 0.76 m 2 ft 6 in Diagonal length of the full court 14.723 m 48 ft 3 in Excluded side strip in singles (each side) 0.46 m 1 ft 6 in A singles court removes 0.46 m from each side of the doubles width, which is why the playing area feels visibly tighter along the flanks. The length never changes, so every long rally and every deep serve still travels the same 13.4 m that doubles players use. Singles Badminton Court Diagram: Understanding Every Line Picture the court from above, split by the net into two equal halves of 6.7 m each. From the net outward, four lines matter for singles play: the short service line, the center line, the singles side line, and the back boundary line. The layout below shows how these lines sit relative to each other on one half of the court. Each service court in singles measures 4.72 m deep and 2.59 m wide, since the serve is allowed to travel all the way to the back boundary line instead of stopping at the shorter doubles service line. Table: Singles Court Lines at a Glance Line Name Position Role in Singles Play Side lines (inner tramlines) 5.18 m apart Mark the playing width for both rallies and serves Short service line 1.98 m from the net The serve must clear this line to be legal Center line Splits the court lengthwise Separates the left and right service courts Back boundary line 13.4 m total length Acts as the outer limit and the long service line for singles Singles vs Doubles Badminton Court Rules: Key Differences Many players confuse singles and doubles boundaries because both formats share the same court markings. Only the active lines change. The table below settles the confusion in one glance. Rule Aspect Singles Court Rule Doubles Court Rule Playing width 5.18 m (inner side lines) 6.1 m (outer side lines) Serve depth Full length, up to the back boundary line Stops at the doubles long service line, 0.76 m short of the back line Back boundary line during serve In play Out of play Outer side strip (0.46 m) Out of bounds In play Total in-play court area Narrower, longer serving zone Wider, shorter serving zone Post/net support position Fixed on doubles side lines regardless of format Same fixed position This comparison explains a common beginner mistake: a shuttle landing in the outer strip counts as in during doubles but as an immediate fault during singles. Singles Badminton Serving Rules Explained Court rules and serving rules work together, since the serving line you use depends entirely on your score. Right Service Court Rule A player serves from, and the opponent receives in, the right service court whenever the server’s score is zero or an even number. This applies at 0, 2, 4, and every even score afterward. Left Service Court Rule The server switches to the left service court the moment their own score becomes odd. A score of 1, 3, 5, or any odd number sends the serve to the left side. Server and Receiver Positioning Rules Both players must stand inside their diagonally opposite service courts without touching the boundary lines. Each server keeps some part of both feet in contact with the court until the racket strikes the shuttle, and the shuttle must stay below 1.15 m in height at the moment of contact. A serve that clears the short service line and lands inside the diagonal service court, on or within its lines, counts as legal.

A standard game runs to 21 points, and a side must win by at least two points. If the score reaches 20-20, play continues until one side leads by two, and if it reaches 29-29, the next point decides the game at 30-29. A match remains best of three games, and the side that wins two
