Is a badminton court 20 by 44 feet?

Yes. 44 × 20 ft is the original size. The metric figures in the Laws, 13.40 × 6.10 m, are the same court rounded to the nearest centimetre.

How much space do you need?

More than the lines, because players run past them.

  • Floor: leave clear space beyond every line for run-off. Sport England's badminton design guidance gives the figures for each level of play.
  • Height: a shuttle that hits the ceiling is a fault, so higher is better. Sport England's guidance gives clear heights too.
  • Light: no window glare, and walls you can see the shuttle against.

Is the line in or out in badminton?

In. Lines count as part of the court, so a shuttle that lands on a line is in.

What is the diagonal of a badminton court?

14.723 m, about 48 ft 4 in. It is used to check the court is square.

What colour are badminton court lines?

White or yellow, so they stand out from the floor.

How long is a badminton net?

At least 6.1 m, so it spans the full doubles court with no gap at the posts.
