The pitch is between 38 and 42 metres long and between 20 and 25 metres wide. This is shorter and narrower than football. The pitch is a hard court and smooth, unlike grass in football. The halves of the game are both twenty minutes long, shorter than the usual 45 minutes in football. There are 6 players on the court in total, including the goalkeeper. Substitutions are unlimited, and the maximum number of subs is 9. Players who break the rules can get yellow or red cards. If a player gets a red card, they can't play in that game anymore. The team that got the red card also has to play with one less player for two minutes or until the other team scores a goal. Another difference from football is that when the ball goes out, instead of throwing it back in, it is kicked in. There is also no offside in futsal.
