Understanding the badminton lines someone can have two main benefits: playing better with a high win ratio and making your badminton court quickly. Your win ratio will increase as you better know the line rules that I will briefly discuss later and avoid losing points with minimum violation of Badminton rules. As lines are directly related to the badminton court size, you can have enough knowledge to make a good court. As the blog title focuses on badminton lines, I also mentioned lines about the racket, net, and shuttlecock. All the details are accurate as I got them from the Badminton World Federation and tried to explain them in an easy way. Let’s draw some lines to avoid ignorance.

Number of Badminton Lines

There are twelve lines in the court of badminton, and one line is below the badminton net. So the total number is thirteen. There are five pairs of lines, with each pair having two lines. Two lines are in a row that differentiate service courts. And one is between them, that is the badminton net line. Understand better with the Diagram. 

Badminton Lines Names

I just mentioned the names of lines without differentiating singles and doubles, as I have explained to them below. For a better understanding, see the Diagram.

  1. Back Boundary lines/Long service lines
  2. Short service lines
  3. Sidelines
  4. Badminton net’s lines
  5. Centerline: service courts differentiating line

Badminton Line Dimensions

Knowing the dimensions of lines is very important because It gives you an idea of the size of the court and how a player has space to move, and you can even make it if you have a location. 

1.2 The lines marking out the court shall be easily distinguishable and preferably be colored white or yellow. (BWF)

Width of Badminton Lines

1.1 The court shall be a rectangle marked out with lines 40 mm wide. (BWF)

Length of Badminton Lines

Badminton Lines have wildly varying length sizes. As you know, I mentioned five names of lines earlier, so let’s explore the lengths of each.

  1. The Length of the Back Boundary line/Long service line is 20 feet.
  2. The length of the Short Service line is 17 feet.
  3. The Length of Sideline is 43.9 feet.
  4. The Length of the Badminton net’s line is 20 feet.
  5. The Length of the Centerline is 12.7 feet.

Badminton Lines for Singles

Following are the lines for singles. You should take care of these lines if you are playing as singles.

  1. Long service line or back boundary line
  2. Sideline for singles

Badminton Lines for Doubles

The following lines are specific for players as they are playing doubles.

  1. Long service line for doubles
  2. Sideline for doubles.

If you have noticed, these lines are selected differently for singles and doubles, making space wider for doubles and longer for singles.

Badminton Lines Singles and Doubles (Similarities)

The following lines are the same for singles and doubles without any difference.

  1. Badminton net line
  2. Centerline
  3. Short service lines
  1. Back Boundary lines/Long service lines

The shuttlecock must land within these lines. The opposite team or player gets a point if shots land outside these lines.

  1. Short service lines

The shuttlecock must land in the opposing service court before the service line. Failure to do so result in a point for the opponent.

  1. Sidelines

Shots must land within these lines; otherwise, a point to the opponent.

  1. Badminton net’s lines

The shuttlecock must pass this line. The opponent gets a point if you do not pass the shuttlecock.

  1. Centerline

In singles, it divides the court into left and eight service courts; in doubles, it serves as a reference for positioning.

    As much as you enjoyed it, I did as well. You are looking forward to what is going to happen next, despite the fact that the picture and the writing are both good. Should you choose to defend this walk, it will be essentially the same each and every time.

  2. I loved even more than you will get done right here. The picture is nice, and your writing is stylish, but you seem to be rushing through it, and I think you should give it again soon. I’ll probably do that again and again if you protect this walk.
